Banker And Customer Realationship5

Banker And Customer Realationship5 - Presentation Transcript

  1. Banker and Customer Relationship
  2. Banker and Customer Relationship
    • The relationship between the banker and customer is very important. Both serve the society to grow and the economy to expand.
    • Before we discuss the relationship between the banker and the customer, it seems necessary that the two terms banker and customer are made clear,
  3. What is the meaning of Banker?
    • A banker is a dealer in capital or more properly a dealer in money.
    • He is an intermediate party between the borrower and the lender. He borrows from one party and lends to another.
    • Banking has been defined as “Accepting for the purpose of lending or investment of deposits of money from the public, repayable on demand or otherwise and withdrawals by check, draft, order or otherwise.
  4. What is the meaning of a Customer?
    • A customer is a person who maintains an account with the bank, without taking into consideration the duration and frequency of operation of his account.
    • To constitute a customer of the bank.
      • One should have an account with the bank.
      • One should deal with the bank in its nature of regular banking business.
      • One should deal with the bank without consideration of the duration and frequency of operation of his account.
  5. Banker and Customer Relationship
    • The relationship between the banker and customer is very important. It is generally studied under the following two heads.
      • General Relationship
      • Special Relationship
  6. General Relationship
    • Debtor and Creditor:
    • The true relationship between banker and customer is primarily of a debtor and creditor.
    • When a customer deposits money with a bank, the bank then is the debtor and the customer is the creditor.
    • The customer expects from the bank that
      • His money will be kept safe by the bank
      • It will be returned on demand within business hours
      • The money will be intact and safe and will give some thing by the way of return (interest).
    • The position is reversed if the customer is advanced loan then the banker becomes creditors and the customer is debtors.
  7. Special Relationship
    • Principal and agent:
    • The special relationship between the customer and the banker is that of principal and agent.
    • The customer (principal) deposits checks, drafts, dividends for collection with the bank.
    • He also gives written instructions to the bank to purchase securities, pay insurance premium, installments of loans etc on his behalf.
    • When the bank performs such agency services, he becomes an agent of his customer.
  8. Bailer and Bailment relationship
    • A bailment is the delivery of goods in trust. A bank may accept the valuables of his customer such as jewellary, documents, securities for safe custody.
    • In such a case the customer is the Bailer and the bank is bailee.
    • The bank (bailee) charges a very small amount as service charges for safe custody of the valuables from his customer (bailer).
    • This relationship between the bank and the customer as bailee and bailer started from the days of earlier goldsmiths.
  9. Pawner and Pawnee:
    • When a customer Pledge goods and documents as security for an advance he then become Pawner (Pledger) and the bank becomes the pawnee (pledgee).
    • The pledged goods are to be returned intact to the pawner after the debt is repaid by him.
  10. Mortgager and Mortgagee relationship:
    • Mortgage is the transfer of an interest in specific immovable property for the purpose of securing the payment of money advanced or to be advanced by way of loan.
    • When a customer pledges a specific immovable property with the bank as security for advance, the customer becomes mortgager and banker is the mortagee.
  11. Bank as a trustee
    • The bank act as a trustee for his customer in those cases where he accept securities and other valuables for safe custody.
    • In such cases the customer continues to be the owner of the valuables deposited with the bank.
  12. Executer, attorney, guarantor
    • The bank also acts as executor, attorney and guarantor for his customer.
    • RIGHTS AND DUTIES OF THE
    • CUSTOMER TOWARDS THE BANKER
    • The main rights and duties of a customer towards the banker in brief are as under:
    • Rights of a customer:
      • A customer who has deposited money can draw check on his account up to the extent of his credit balance or according to overdrawing limit sanctioned by the bank.

Hypertension and Diabetes

James Reed, MD, Professor of Medicine at Morehouse School of Medicine, was the third speaker in the morning session and further elaborated on the relationship between hypertension and diabetes.

The Relationship Between Hypertension and Diabetes

There is an intimate relationship between diabetes mellitus (DM) and hypertension. It is estimated that if diabetic patients live long enough, approximately 75% will develop hypertension. The following mechanisms mediate the development of hypertension in diabetes:
  • Activation of the tissue-based renin-angiotensin-aldosterone axis;

  • Volume expansion secondary to hyperglycemia;

  • Reduced baroreceptor response;

  • Autonomic dysfunction (exaggerated orthostatic response and loss of circadian rhythm without the normal nighttime depression in blood pressure); and

  • Endothelial dysfunction and vascular oxidative stress.

Hypertension is more difficult to control in diabetic patients than in nondiabetic patients. Several published studies[1] corroborate the need for multiple antihypertensive agents -- on average, 3 -- to achieve target blood pressure goals in this population.
In addition, increasing systolic blood pressure portends even greater increases in mortality in diabetic patients than in nondiabetic patients, and even at normal blood pressure, the risk for cardiovascular death is 25-fold greater. The UK Prospective Diabetes Study (UKPDS) plotted the parallel increase in microvascular events, such as blindness, gastroparesis, and end-stage renal disease (ESRD), against the occurrence of myocardial infarction, a macrovascular event. The incidence of both micro- and macrovascular events increases proportionately in diabetic persons at each increasing increment of systolic blood pressure.[2] The bottom line is that to prevent both types of events, blood pressure must be aggressively managed and controlled.

Predicting Mortality and Morbidity in Diabetic Nephropathy

Diabetes and its effect on the microvasculature is well known, especially with regard to the kidney. Diabetes mellitus is the leading cause of ESRD, and the overall incidence of ESRD has been steadily increasing each year. However, these microvascular changes actually occur, on average, 8-10 years before the diagnosis. Ideally, there would be an easily administered test to measure insulin resistance or prediabetes. Unfortunately, the current methods of euglycemic insulin clamping are nonstandardized and too complex to use in everyday practice; they are used only in research studies.
Microalbuminuria, defined as urinary albuminexcretion > 4.8 micrograms/min, reflects the endothelial damage that occurs before diagnosis, and progression to macroalbuminuria predicts hypertension, renal disease, and other complications of diabetes.[3] Microalbuminuria is also a strong and independent determinant ofcoronary heart disease and death.[4] There is a positive correlation between the degree of proteinuria and cardiovascular death as well as the incidence of stroke and coronary heart disease.[5]

Treatment Recommendations in the Setting of Hypertension and Diabetic Nephropathy

The most effective first-line agent for control of blood pressure in patients with renal disease or DM is an angiotensin-converting enzyme (ACE) inhibitor, as recommended in the guidelines of both the Canadian and British Hypertension Societies, the National Kidney Foundation, the World Health Organization, and the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 6). Dr. Reed disagrees with JNC 6, however, that a diuretic should be the first-line agent if no albuminuria is present. He believes that an ACE inhibitor should be used as a first choice in this instance as well, although an average of 2-3 medications will usually be necessary to control blood pressure in most diabetic patients. Lewis and colleagues[6] were the first to demonstrate the benefit of an ACE inhibitor in patients with diabetic nephropathy. In their study, captopril compared with placebo slowed the rate of progression to dialysis and transplantation in a cohort of 409 patients who had type 1 diabetes and ESRD and were followed for 4 years (P = .006). Several later studies corroborated this renal survival benefit by using enalapril or benazepril and following patients for 3-5 years.
Despite the preponderance of evidence, many physicians still do not use ACE inhibitors in this context. Only an estimated 39% of US patients who should be taking ACE inhibitors according to current treatment guidelines are actually receiving them. This may be due to a fear of inducing an increase in serum creatinine level. Bakris and Weir[7] examined this question by reviewing 12 randomized trials to determine whether the use of ACE inhibitors or angiotensin-receptor blockers results in long-term protection against a decline in renal function in patients with renal insufficiency. They found that a limited elevation in serum creatinine level (≤ 30% above baseline) was usually seen in the first 2 weeks after initiation of therapy with an ACE inhibitor or angiotensin-receptor blocker. However, data from these studies in patients with diabetic and nondiabetic renal disease demonstrated that if an increase does occur, it stabilizes quickly and does not progressively worsen, and the effect on glomerular filtration rate is reversible. If serum creatinine level increases more than 30% on a long-term basis within the first month or if hyperkalemia occurs, the drug should be withdrawn.[7] In general, however, results indicated that use of drugs that block the renin-angiotensin system is appropriate in patients with renal insufficiency.
A second concern about using ACE inhibitors in diabetic hypertensive patients was their alleged relative ineffectiveness in the African-American population. In a study using trandolapril, Weir and colleagues[8] showed that systolic blood pressure decreased similarly in African-American patients and in white patients but at higher doses in the former group (4 mg vs 1 mg). Therefore, when proper doses are used, any disparity in effect can be eliminated.[8]
The renal protection offered by the renin-angiotensin-aldosterone blockade has multiple mechanisms, including hemodynamic effects of reduction in systemic blood pressure and glomerular capillary pressure because of efferent glomerular arteriolar dilation and proteinuria and nonhemodynamic effects of stimulation for extracellular matrix degradation and inhibition of macrophage infiltration.
Calcium-channel blockers (CCBs) are effective antihypertensive drugs, but their effects on urinary protein excretion in patients with proteinuric renal diseases and renal insufficiency has been unclear. A review of published data demonstrates that in patients with proteinuria, the dihydropyridine CCBs do not lower proteinuria, despite a reduction of blood pressure. However, information on the effects of the nondihydropyridine CCBs suggests that these agents might be just as beneficial as ACE inhibitors.[9] Subsequent studies using the combination of trandolapril (an ACE inhibitor) and verapamil (a non- dihydropyridine CCB) show a greater reduction of proteinuria than is seen with either agent alone. The reduction from the combination also occurs at lower doses of each drug and is independent of further reductions in arterial pressure.[10]
The hypertensive diabetic patient with increased capillary pressure and proteinuria has a high risk for renal disease and for coronary artery disease. Therefore, the combination of an ACE inhibitor and non-dihydropyridine CCB is recommended.[11] When taken together, these drugs reduce blood pressure, heart rate, and proteinuria as well as cardiovascular risk and renal disease progression.

Relationship Between Banker and Customer:

The relationship between a banker and a customer depends on the activities; products or services provided by bank to its customers or availed by the customer. Thus the relationship between a banker and customer is the transactional relationship. Bank’s business depends much on the strong bondage with the customer. “Trust” plays an important role in building healthy relationship between a banker and customer.

Definition of a ‘BANKER’

The Banking Regulations Act (B R Act) 1949 does not define the term ‘banker’ but defines what banking is?

As per Sec.5 (b) of the B R Act “Banking' means accepting, for the purpose of lending or investment, of deposits of money from the public repayable on demand or otherwise and withdrawable by cheque, draft, order or otherwise."

As per Sec. 3 of the Indian Negotiable Instruments Act 1881, the word “banker includes any person acting as banker and any post office savings bank”.

According to Sec. 2 of the Bill of Exchange Act, 1882, ‘banker includes a body of persons, whether incorporated or not who carry on the business of banking.’

Sec.5(c) of BR Act defines "banking company" as a company that transacts the business of banking in India. Since a banker or a banking company undertakes banking related activities we can derive the meaning of banker or a banking company from Sec 5(b) as a body corporate that:

(a) Accepts deposits from public.

(b) Lends or

(c) Invests the money so collected by way of deposits.

(d) Allows withdrawals of deposits on demand or by any other means.

Accepting deposits from the ‘public’ means that a bank accepts deposits from anyone who offers money for the purpose. Unless a person has an account with the bank, it does not accept deposit. For depositing or borrowing money there has to be an account relationship with the bank. A bank can refuse to open an account for undesirable persons. It is banks right to open an account. Reserve Bank of India has stipulated certain norms “Know Your Customer” (KYC) guidelines for opening account and banks have to strictly follow them.

In addition to the activities mentioned in Sec.5 (b) of B R Act, banks can also carry out activities mentioned in Sec. 6 of the Act.


Who is a ‘Customer’?

The term Customer has not been defined by any act. The word ‘customer’ has been derived from the word ‘custom’, which means a ‘habit or tendency’ to-do certain things in a regular or a particular manner’s .In terms of Sec.131 of Negotiable Instrument Act, when a banker receives payment of a crossed cheque in good faith and without negligence for a customer, the bank does not incur any liability to the true owner of the cheque by reason only of having received such payment. It obviously means that to become a customer account relationship is must. Account relationship is a contractual relationship.

It is generally believed that any individual or an organisation, which conducts banking transactions with a bank, is the customer of bank. However, there are many persons who do utilize services of banks, but do not maintain any account with the bank.

Thus bank customers can be categorized in to four broad categories as under:

(a)Those who maintain account relationship with banks i.e. Existing customers.
(b)Those who had account relationship with bank i.e. Former Customers
(c)Those who do not maintain any account relationship with the bank but frequently
visit branch of a bank for availing banking facilities such as for purchasing a
draft, encashing a cheque, etc. Technically they are not customers, as they do
not maintain any account with the bank branch.
(d)Prospective/ Potential customers: Those who intend to have account relationship
with the bank. A person will be deemed to be a 'customer' even if he had only
handed over the account opening form duly filled in and signed by him to the bank
and the bank has accepted the it for opening the account, even though no
account has actually been opened by the bank in its books or record.

The practice followed by banks in the past was that for opening account there has to be an initial deposit in cash. However the condition of initial cash deposit for opening the account appears to have been dispensed with the opening of ‘No Frill’ account by banks as per directives of Reserve Bank of India. ‘No Frill’ accounts are opened with ‘Nil’ or with meager balance.

The term 'customer' is used only with respect to the branch, where the account is maintained. He cannot be treated as a ‘customer' for other branches of the same bank. However with the implementation of’ ‘Core Banking Solution’ the customer is the customer of the bank and not of a particular branch as he can operate his account from any branch of the bank and from anywhere. In the event of arising any cause of action, the customer is required to approach the branch with which it had opened account and not with any other branch.


‘Know Your Customer’ Guidelines and Customer:

As per ‘Know Your Customer’ guidelines issued by Reserve Bank of India, customer has been defined as:

(i)A person or entity that maintains an account and/or has a business relationship
with the bank;
(ii)One on whose behalf the account is maintained (i.e. the beneficial owner);
(iii)Beneficiaries of transactions conducted by professional intermediaries, such as
Stock Brokers, Chartered Accountants, Solicitors etc. as permitted under the
law, and
(iv)Any person or entity connected with a financial transaction, which can pose
significant reputational or other risks to the bank, say, a wire transfer or
issue of a high value demand draft as a single transaction.

Banker-Customer Relationship:

Banking is a trust-based relationship. There are numerous kinds of relationship between the bank and the customer. The relationship between a banker and a customer depends on the type of transaction. Thus the relationship is based on contract, and on certain terms and conditions.

These relationships confer certain rights and obligations both on the part of the banker and on the customer. However, the personal relationship between the bank and its customers is the long lasting relationship. Some banks even say that they have generation-to-generation banking relationship with their customers.The banker customer relationship is fiducial relationship. The terms and conditions governing the relationship is not be leaked by the banker to a third party.

Classification of Relationship:

The relationship between a bank and its customers can be broadly categorized in to General Relationship and Special Relationship.

If we look at Sec 5(b) of Banking Regulation Act, we would notice that bank’s business hovers around accepting of deposits for the purposes of lending. Thus the relationship arising out of these two main activities are known as General Relationship. In addition to these two activities banks also undertake other activities mentioned in Sec.6 of Banking Regulation Act. Relationship arising out of the activities mentioned in Sec.6 of the act is termed as special relationship.

General Relationship:

Debtor-Creditor: When a 'customer' opens an account with a bank, he fills in and signs the account opening form. By signing the form he enters into an agreement/contract with the bank. When customer deposits money in his account the bank becomes a debtor of the customer and customer a creditor. The money so deposited by customer becomes bank’s property and bank has a right to use the money as it likes. The bank is not bound to inform the depositor the manner of utilization of funds deposited by him. Bank does not give any security to the depositor i.e. debtor. The bank has borrowed money and it is only when the depositor demands, banker pays. Bank’s position is quite different from normal debtors.
Banker does not pay money on its own, as banker is not required to repay the debt voluntarily. The demand is to be made at the branch where the account exists and in a proper manner and during working days and working hours.

The debtor has to follow the terms and conditions of bank said to have been mentioned in the account opening form. {Though the terms and conditions are not mentioned in the account opening form, but the account opening form contains a declaration that the terms and conditions have been read and understood or has been explained. In fact the terms and conditions are mentioned in the passbook, which is issued to the customer only after the account has been opened.}

In the past while opening account some of the banks had the practice of giving a printed handbill containing the terms and conditions of account along with the account opening form. This practice has since been discontinued. For convenience and information of prospective customers a few banks have uploaded the account opening form, terms and conditions for opening account, rate charge in respect of various services provided by the bank etc., on their web site.

While issuing Demand Draft, Mail / Telegraphic Transfer, bank becomes a debtor as it owns money to the payee/ beneficiary.

2. Creditor–Debtor: Lending money is the most important activities of a bank. The resources mobilized by banks are utilized for lending operations. Customer who borrows money from bank owns money to the bank. In the case of any loan/advances account, the banker is the creditor and the customer is the debtor. The relationship in the first case when a person deposits money with the bank reverses when he borrows money from the bank. Borrower executes documents and offer security to the bank before utilizing the credit facility.

In addition to opening of a deposit/loan account banks provide variety of services, which makes the relationship more wide and complex. Depending upon the type of services rendered and the nature of transaction, the banker acts as a bailee, trustee, principal, agent, lessor, custodian etc.

Special Relationship:

1. Bank as a Trustee:

As per Sec. 3 of Indian Trust Act, 1882

‘ A "trust" is an obligation annexed to the ownership of property, and arising out of a confidence reposed in and accepted by the owner, or declared and accepted by him, for the benefit of another, or of another and the owner.’ Thus trustee is the holder of property on behalf of a beneficiary.

As per Sec. 15 of the ‘Indian Trust Act, 1882 ‘A trustee is bound to deal with the trust-property as carefully as a man of ordinary prudence would deal with such property if it were his own; and, in the absence of a contract to the contrary, a trustee so dealing is not responsible for the loss, destruction or deterioration of the trust-property.’ A trustee has the right to reimbursement of expenses (Sec.32 of Indian Trust Act.).

In case of trust banker customer relationship is a special contract. When a person entrusts valuable items with another person with an intention that such items would be returned on demand to the keeper the relationship becomes of a trustee and trustier. Customers keep certain valuables or securities with the bank for safekeeping or deposits certain money for a specific purpose (Escrow accounts) the banker in such cases acts as a trustee. Banks charge fee for safekeeping valuables


2. Bailee – Bailor:

Sec.148 of Indian Contract Act, 1872, defines "Bailment" "bailor" and "bailee".
A "bailment" is the delivery of goods by one person to another for some purpose,

upon a contract that they shall, when the purpose is accomplished, be returned or
otherwise disposed of according to the directions of the person delivering them.
The person delivering the goods is called the "bailor". The person to whom they
are delivered is called, the "bailee".

Banks secure their advances by obtaining tangible securities. In some cases physical possession of securities goods (Pledge), valuables, bonds etc., are taken. While taking physical possession of securities the bank becomes bailee and the customer bailor. Banks also keeps articles, valuables, securities etc., of its customers in Safe Custody and acts as a Bailee. As a bailee the bank is required to take care of the goods bailed.

3.Lessor and Lessee:

Sec.105 of ‘Transfer of property Act 1882’ defines lease, Lessor, lessee, premium and rent. As per the section

“A lease of immovable property is a transfer of a right to enjoy such property, made for a certain time, express or implied, or in perpetuity, in consideration of a price paid or promised, or of money, a share of crops, service or any other thing of value, to be rendered periodically or on specified occasions to the transferor by the transferee, who accepts the transfer on such terms.”

Definition of Lessor, lessee, premium and rent :

(1)The transferor is called the lessor,
(2)The transferee is called the lessee,
(3)The price is called the premium, and
(4)The money, share, service or other thing to be so rendered is called the rent.”

Providing safe deposit lockers is as an ancillary service provided by banks to customers. While providing Safe Deposit Vault/locker facility to their customers bank enters into an agreement with the customer. The agreement is known as “Memorandum of letting” and attracts stamp duty.
The relationship between the bank and the customer is that of lessor and lessee. Banks lease (hire lockers to their customers) their immovable property to the customer and give them the right to enjoy such property during the specified period i.e. during the office/ banking hours and charge rentals. Bank has the right to break-open the locker in case the locker holder defaults in payment of rent. Banks do not assume any liability or responsibility in case of any damage to the contents kept in the locker. Banks do not insure the contents kept in the lockers by customers.

4. Agent and Principal:

Sec.182 of ‘The Indian Contract Act, 1872’ defines “an agent” as a person employed to do any act for another or to represent another in dealings with third persons. The person for whom such act is done or who is so represented is called “the Principal”.

Thus an agent is a person, who acts for and on behalf of the principal and under the latter’s express or implied authority and the acts done within such authority are binding on his principal and, the principal is liable to the party for the acts of the agent.
Banks collect cheques, bills, and makes payment to various authorities viz., rent, telephone bills, insurance premium etc., on behalf of customers. . Banks also abides by the standing instructions given by its customers. In all such cases bank acts as an agent of its customer, and charges for theses services. As per Indian contract Act agent is entitled to charges. No charges are levied in collection of local cheques through clearing house. Charges are levied in only when the cheque is returned in the clearinghouse.

5. As a Custodian:
A custodian is a person who acts as a caretaker of some thing. Banks take legal responsibility for a customer’s securities. While opening a dmat account bank becomes a custodian.
6. As a Guarantor: Banks give guarantee on behalf of their customers and enter in to their shoes. Guarantee is a contingent contract. As per sec 31,of Indian contract Act guarantee is a " contingent contract ". Contingent contract is a contract to do or not to do something, if some event, collateral to such contract, does or does not happen.
It would thus be observed that banker customer relationship is transactional relationship.
Termination of relationship between a banker and a customer:
The relationship between a bank and a customer ceases on:
(a) The death, insolvency, lunacy of the customer.
(b) The customer closing the account i.e. Voluntary termination
(c) Liquidation of the company
(d) The closing of the account by the bank after giving due notice.
(e) The completion of the contract or the specific transaction.

The relationship developed between a banker and customer involves some duties on the part of both.

Duties of a banker:

A 'Banker' has certain duties vis-à-vis his customer. These are:

(a)Duty to maintain secrecy/confidentiality of customers' accounts.
(b)Duty to honour cheques drawn by customers on their accounts and collect cheque,
bills on his behalf.
(c)Duty to pay bills etc., as per standing instructions of the customer.
(d)Duty to provide proper services.
(e)Duty to act as per the directions given by the customer. If directions are not
given the banker has to act according to how he is expected to act.
(f)Duty to submit periodical statements i.e. informing customers of the state of the
account
(g)Articles/items kept should not be released to a third party without due
authorization by the customer

Duty to maintain secrecy:

Banker has a duty to maintain secrecy of customers' accounts. Maintaining secrecy is not only a moral duty but bank is legally bound to keep the affairs of the customer secret. The principle behind this duty is that disclosure about the dealings of the customer to any unauthorized person may harm the reputation of customer and the bank may be held liable. The duty of maintaining secrecy does not cease with the closing of account or on the death of the account holder.

As per Sec. 13 of “Banking Companies Acquisition and Transfer of Undertakings Act 1970”-

“Every corresponding new bank shall observe, except as otherwise required by law, the practices and usages customary among bankers, and, in particular, it shall not divulge any information relating to or to the affairs of its constituents except in circumstances in which it is, in accordance with law or practices and usages customary among bankers, necessary or appropriate for the corresponding new bank to divulge such information.”

Maintaining secrecy is implied terms of the contract with the customer which bank enters into with the customer at the time of opening an account.

Bank has not only to maintain secrecy of transactions, but secrecy is also to be maintained in respect of operations through ATM/ debit cards. Bank has also to maintain secrecy of user ID pins with due care so that it does fall in wrong hands.


Failure to maintain secrecy:


Bank is liable to pay damages to the account holder for loss of money and reputation if it fails in its duty to maintain secrecy and discloses information relating to a customer's account or conduct of the account to any unauthorized person.
Bank can also be liable to the third party if its wrongful disclosure harms the interest of the third-party. If bank Knowingly furnishes wrong information
There has been a misrepresentation
Over estimation of favourable opinion

Circumstances under which banker can disclose information of customer's account:

A bank can disclose information regarding customer's account to a person(s) under the following circumstances.

(a)Under compulsion of law.
(b)Under banking practices.
(c)For protecting national interest.
(d)For protecting bank’s own interest
(e)Under express or implied consent of the customer

Disclosure under compulsion of law:

Banks disclose information to various authorities who by virtue of powers vested in them under provisions of various acts require banks to furnish information about customer’s account. The information is called under:

(i)Section 4 of Banker's Book Evidence Act, 1891
(ii)Section 94 (3) of Code of Civil Procedure Act, 1908
(iii)Section 45 (B) of Reserve Bank of India Act, 1934
(iv)Section 26 of Banking Regulation Act, 1949
(v)Section 36 of Gift Tax Act, 1958
(vi)Sections 131, 133 of Income Tax Act, 1961
(vii)Section 29 of Industrial Development Bank of India Act, 1964
(viii)Section 12of Foreign Exchange Management Act, (FEMA) 1999
(ix)Section 12 of the Prevention of Money Laundering Act, 2002

Banks are required to furnish only the called for information (no additional information is to be furnished) on receipt of written request of the person who is vested with the authority to call for such information under the said acts. The customer is kept informed about the disclosure of the information.

Disclosure under banking practices:

In order to ascertain financial position and credit worthiness of the person banks obtain information from other banks with which they are maintaining accounts. It is an established practice among bankers and implied consent of the customer is presumed to exist. The opinion is given in strictest confidence and without responsibility on the part of the bank furnishing such information. Credit information is furnished in coded terms to other banks on IBA format and without signatures.

2.Duty to provide proper accounts :

Banks are under duty bound to provide proper accounts to the customer of all the transactions done by him. Bank is required to submit a statement of accounts / passbook to the customer containing all the credits and debits in the account.

3.Duty to honour cheques:

As 'banking' means accepting of deposits withdrawable by cheque, draft, order or otherwise, the banker is duty bound to honour cheques issued by the customers on their accounts.
Sec. 31of Negotiable Instruments Act, 1881 specifies the liability of drawee of cheque. As per Sec. 31 “The drawee of a cheque having sufficient funds of the drawer in his hands properly applicable to the payment of such cheque must pay the cheque when duly required so to do, and, in. default of such payment, must compensate the drawer for any loss or damage caused by such default.”

Therefore it is the duty of a bank to honour the cheques issued by the account holder if:

The cheque has been properly drawn and is in order in all respects i.e. it is properly dated, amount in words and figures have been expressed properly, is neither stale nor post dated nor mutilated and the signature of accountholder tallies with the specimen recorded with the bank. The cheque should be drawn on the branch where the account is maintained. (Due to implementation of technology and core banking solution a customer can present cheques on any branch of a bank. RBI has advised banks to issue multi city cheques to account holders.)
(a)There is sufficient balance in the account and the balance is properly
applicable for payment of the cheque.
(b)The cheque is presented for payment on a working day and during the business
hours of the branch.
(c)Endorsements on the cheque are regular and proper.
(d)The payment of the cheque is not countermanded by the drawer

Duty to honour cheques ceases on receipt of:

(a)Stop payment instructions from the account holder.
(b)Notice about the death of the drawer.
(c)A garnishee order attaching the balance in the account or an income-tax
attachment order received by the banker.
(d)Drawer of the cheque becoming insolvent and/or a lunatic at the time of drawing
the cheque.
Bank can refuse to honour the cheques if:There is in sufficient 1balance in the account to make payment of the cheque.
Cheque issued does not pertain to the account on which it has been drawn.
1.If the cheque is not in order (post dated, stale, payment countermanded, amount in
words and figure differs, etc.)
2.The balances held in account are earmarked for some specific purpose and the
remaining balance is not sufficient to honour the cheque.

Rights of a banker:
It is not that the bank has only duties to wards its customers, it too has certain rights vis-à-vis his customers. The rights can broadly be classified as:

Right of General Lien
a)Right of Set-Off
b)Right of Appropriation
c)Act as per the mandate of customer
d)Right to Charge Interest, Commission, Incidental Charges etc.

Lien:

A lien is the right of a creditor in possession of goods, securities or any other assets belonging to the debtor to retain them until the debt is repaid, provided that there is no contract express or implied, to the contrary. It is a right to retain possession of specific goods or securities or other movables of which the ownership vests in some other person and the possession can be retained till the owner discharges the debt or obligation to the possessor. The creditor (bank) has the right to maintain the security of the debtor but not to sell it. There are two types of lien viz.

1.Particular Lien and
2.Right of General Lien

(a) Particular Lien:

A 'particular lien' gives the right to retain possession only of those goods in respect of which the dues have arisen. It is also termed as ordinary lien. If the bank has obtained a particular security for a particular debt, then the banker's right gets converted into a particular lien.

(b) Right of General Lien:

Banker has a right of general lien against his borrower. General lien confers banks right in respect of all dues and not for a particular due. It is a statutory right of the bank and is available even in absence of an agreement but it does not confer the right to pledge. A 'general lien' gives the right to retain possession of any goods in the legal possession of the creditor until the whole of the debt due from the debtor is paid.

Section 171 of Indian Contract Act, 1872 confers the right of general lien to banks. As per the section “ Bankers, factors, wharfingers, attorneys of a High Court and policy-brokers may, in the absence of a contract to the contrary, retain, as a security for a general balance of account any goods bailed to them; but no other persons have a right to retain, as a security for such balance, goods bailed to them, unless there is an express contract to the effect.”

Bank has a right of lien only when goods, securities are received in the capacity as a creditor. While granting advances banks take documents. These documents confer right to convert general lien as an implied pledge. A banker’s lien is more than a general lien, it is an implied pledge and he has the right to sell the goods in case of default Bank has a 'Right of Sale' of goods under lien. Banker's right of lien is not barred by the Law of Limitation.

Exercising Right of Lien:

Bank has the right of lien on goods and securities entrusted to him legally and standing in the name of the borrower.
Bank can exercise right of lien on the securities in its possession for the dues of the same borrower, even after the loan taken against that particular security has been re-paid.
Right of lien can be exercised on bills, cheques, promissory notes, share certificates, bonds, debentures etc.

Where right of lien cannot be exercised:

Bank cannot exercise right of lien on goods received for safe custody, goods held in capacity as a trustee, or as an agent of the customer, SDV, or left in bank by mistake

Right of set-off:

The banker has the right to set off the accounts of its customer. It is a statutory right available to a bank, to set off a debt owned to him by a creditor from the credit balances held in other accounts of the borrower. The right of set-off can be exercised only if there is no agreement express or implied to the contrary. This right is applicable in respect of dues that are due, are becoming due i.e. certain and not contingent. It is not applicable on future debts. It is applicable in respect of deposits that are due for payment.

The right of set off enables bank to combine all kinds of credit and debit balances of a customer for arriving at a net sum due.

The right is also available for deposits kept in other branches of the same bank. The right can be exercised after death, insolvency, and dissolution of a company, after receipt of a garnishee/ attachment order .The right is also available for time barred debts.

Deposits held in the name of a guarantor cannot be set off to the debit balance in borrowers account until a demand is made to the guarantor and his liability becomes certain. Banks cannot set off the credit balance of customer's personal account for a joint loan account of the customer with another person unless both the joint accountholders are jointly and severally liable. Banks exercise the Right of set off only after serving a notice on the customer informing him that the bank is going to exercise the right of set-off.

Automatic right of set off:

Depending on the situation, sometimes the set off takes place automatically without the permission from the customer. In the following events the set off happens automatically i.e. without the permission from the customer.

a)On the death of the customer,
b)On customer becoming insolvent.
c)On receipt of a Garnishee order on customer’s account by court.
d)On receipt of a notice of assignment of credit balance by the customer to the
banker.
e)On receipt of notice of second charge on the securities already charged to the
bank.

Conditions while exercising right of Set - Off:

a)The account should be in the sole name of the customer.
b)The amount of debts must be certain and measurable.
c)There should not be any agreement to the contrary
d)Funds should not be held in trust accounts
e)The right cannot be exercised in respect of future or contingent debts.
f)The banker has the right to exercise this right before a garnishee order is received by it.

Right of Appropriation:

It is the right of the customers to direct his banker against which debt (when more than one debt is outstanding) the payment made by him should be appropriated. In case no such direction is given, the bank can exercise its right of appropriation and apply it in payment of any debt. Section 59,60 and 61 of Indian Contract Act, 1872 lays down the rules of appropriation.

Sec.59.Application of payment where debt to be discharged is indicated: (i.e.– As per borrowers instructions)

Where a debtor, owing several distinct debts to one person, makes a payment to him, either with express intimation, or under circumstances implying that the payment is to be applied to the discharge of some particular debt, the payment, if accepted, must be applied accordingly.

Sec.60. Application of payment where debt to be discharged is not indicated: (i.e. in the absence of express or implied intention of debtor)

Sec.60 of the Indian Contract Act states that if the debtor does not intimate or there is no circumstance of indicating how the payment is to be used, the right of appropriation is vested in the creditor.

According to the Act, “Where the debtor has omitted to intimate and there are no other circumstances, indicating to which debt the payment is to be applied, the creditor may apply it at his discretion to any lawful debt actually due and payable to him from the debtor, whether its recovery is or is not barred by the law in force for the time being as to the limitation of suits.”

Sec.61.Application of payment where neither party appropriates.
Where neither party makes any appropriation the payment shall be applied in discharge of the debts in order of time, whether they are or are not barred by the law in force for the time being as to the limitation of suits. If the debts are of equal standing, the payment shall be applied in discharge of each proportionally.

Unless there is an agreement to the contrary, any payment made by a debtor is applied first towards interest and thereafter towards principal. If a customer has only one account and he deposits and withdraws money from it regularly, the order in which the credit entry will set off the debit entry is in the chronological order, this is known as Clayton’s rule.

Rule in Clayton’s case:

The rule was laid down in famous Devayanas Vs. Noble. The rule applies to running accounts like CC/ OD with debit balance. The rule states that each withdrawal in a debit account is considered as a new loan and each deposit as a repayment in that chronological order.

Banker's right to charge interest, commission, incidental charges etc. :
Banker has an implied right to charge for services rendered and sold to a customer. Bank charges interest on amount advanced, processing charges for the advance, charges for non-utilization of credit facilities sanctioned, charges commission, exchange, incidental charges etc. depending on the terms and conditions of advance banks charge interest at monthly, quarterly or semiannually or annually. Banks charge customers if the balance in deposit account falls below the prescribed amount. Usually the bank informs such charges to the customer by various means.

Nomination Facility:

Nomination is expression of wish of a person about transfer of his assets after his death to a named person. Nomination is not a will but it serves the purpose of will. In terms of Sections 45ZA to 45 ZF of the Banking Regulation Act, 1949, Banking Companies (Nomination) Rules, 1985 have been framed. Nomination facility simplifies the procedure for settlement of claims of deceased depositors and locker holders. In an unfortunate event of the death of a depositor, nomination enables the bank to make payment to the nominee of a deceased depositor, of the amount standing to the credit of the depositor, return the articles left by a deceased person in the bank's safe custody to the nominee without asking for succession certificate or verifying claims of legal heirs.
Nomination does not take away the rights of legal heirs on the estate of the deceased. The nominee receives the money from the bank as a trustee of the legal heirs. In the case of a joint deposit account the nominee's right arises only after the death of all the depositors. Nomination facility is intended for individuals and sole proprietary concerns.
Where the nominee is a minor, the depositor making the nomination appoints any person to receive the amount of deposit in the event of his death during the minority of the nominee. A person legally empowered to operate a minor's account can file a nomination on behalf of the minor.
Nomination can be made in account opening form itself or on a separate form indicating the name and address of the nominee. The account holders can change the nomination any time. There can be only one Nominee for a deposit account whether held singly or jointly. There can be two nominees for a jointly held locker.

Availability of the Nomination facility:

Nomination facility is available for all types of bank deposits, safe deposit lockers, and safe custody articles. This is also applicable to deposits having operating instructions "Either or Survivor".
Nomination can be made in favour of one person only.
In case of a joint account, nomination is to be made by all depositors jointly.
Nomination cannot be made in accounts where deposits are held in a representative capacity e.g. trust accounts etc. and in accounts of partnership firms, H.U.F., companies, associations, clubs etc.
Nomination can be made in favour of a minor. However while making the nomination, the nominee has to appoint another person (not a minor), to receive the amount of the deposit on behalf of the nominee in the event of the death of the depositor during the minority of the nominee. Date of birth of minor be obtained and noted.
A nomination will continue to be in force even on renewal of term deposit, unless specifically cancelled or changed.
Banks obtain separate nomination form for each term deposit receipt
A non-resident can be nominated as a nominee in a resident account
In case of non-resident nominees, the amount entitled to him from the account(s)/ deposits(s) of a deceased person, will be credited to his NRO account. The amount so credited cannot be remitted outside India.

Insurance of Bank Deposits:

The Deposit Insurance and Credit Guarantee Corporation of India, a public limited company promoted by Reserve Bank of India, insure bank deposits. The authorised capital of the Corporation is Rs.50 crore, which is fully issued and subscribed by the Reserve Bank of India (RBI). The management of the Corporation vests in a Board of Directors of which a Deputy Governor, Reserve bank of India, is the Chairman.

The Corporation protects the interest of depositors and infuses confidence by providing deposit insurance on account of failure of banks. All commercial banks including the branches of foreign banks functioning in India, local area banks, regional rural banks, all eligible co-operative banks are covered under the Deposit Insurance Scheme. The insurance covers the loss of all or part of their deposits in all branches of a bank to a maximum of Rs.1, 00,000. It insures all deposits such as savings, fixed, current, recurring, etc except the following types of deposits.

(i) Deposits of foreign Governments,

(ii) Deposits of Central/State Governments,

(iii) Inter-bank deposits,

(iv) Deposits of the State Land Development Banks with the State co-operative bank;
(v) any amount due on account of and deposit received outside India
(vi) any amount, which has been specifically exempted by the corporation with the previous approval of Reserve Bank of India.

The Corporation charges insurance premium from banks on deposits @10 paisa per Rs.100of assessable deposits per annum. The premium is charged twice a year on the assessable deposits as at 31st March and 30th September. Though the premium is charged on the full amount of deposit kept by depositors in a bank is insured up to a maximum of Rs.1,00,000 (Rupees One Lakh) only for both principal and interest amount.
The corporation pays to each depositor through the liquidator, the amount of his deposit up to Rupees one lakh within two months from the date of receipt of claim list from the liquidator. If a bank is reconstructed or amalgamated / merged with another bank, it pays the bank concerned, the difference between the full amount of deposit or the limit of insurance cover in force at the time, whichever is less and the amount received by him under the reconstruction / amalgamation scheme within two months from the date of receipt of claim list from the transferee bank / Chief Executive Officer of the insured bank/transferee bank as the case may be.
In the second report of Narasimham Committee (April 1998) on “Banking Sector Reforms” recommendations have been made for reforming scheme of Deposit insurance. The committee has recommended that instead of “flat’” rate premium, it should be ‘ risk based’ or ‘variable rate’ premium.

Know Your Customer Norms and Cash transactions:

The objective of KYC guidelines is to prevent banks from being used, intentionally or unintentionally, by criminal elements for money laundering activities. KYC procedures enable banks to know/understand their customers and their financial dealings better, which in turn help them, manage their risks prudently. Necessary checks before opening a new account ensures that the identity of the customer does not match with any person with known criminal background or with banned entities such as individual terrorists or terrorist organizations etc. and that no account is opened in anonymous or fictitious/ benami name(s).
Banks are supposed to adopt due diligence and appropriate KYC norms at the time of opening of accounts. The objectives of the KYC are to ensure appropriate customer identification and to monitor transactions of a suspicious nature. While opening an account a bank is supposed to obtain all information necessary for establishing the identity/legal existence of each new customer by taking and verifying the introductory reference from an existing account holder/a person known to the bank or on the basis of documents provided by the customer. The means of establishing identity can be passport, driving license etc. In respect of existing customers banks are required to complete customer identification at the earliest.

Ceiling and monitoring of cash transactions

As per RBI guidelines issued under Section 35 (A) of the Banking Regulation Act, 1949:
(i)Banks are required to issue travellers cheques, demand drafts, mail transfers, and telegraphic transfers for Rs.50, 000 and above only by debit to customers’ accounts or against cheques and not against cash. While purchasing travellers cheques, demand drafts, mail transfers, and telegraphic transfers for Rs.50, 000 and above purchaser has to mention his Permanent Income Tax Account Number (PAN) on the application.
(ii) The banks are required to keep a close watch of cash withdrawals and deposits for Rs.10 lakhs and above in deposit, cash credit or overdraft accounts and keep record of details of these large cash transactions in a separate register. Branches of banks are required to report all cash deposits and withdrawals of Rs.10 lakhs and above as well as transactions of suspicious nature with full details in fortnightly statements to their controlling offices.

Bankers’ Fair Practice Code:
Indian Banks’ Association has prepared a code, which sets standards of fair banking practices. This document is a broad framework under which the rights of common depositors are recognized. It is a voluntary Code that promotes competition and encourages market forces to achieve higher operating standards for the benefit of customers. The Code applies to current, savings and all other deposit accounts, collection and remittance services offered by the banks, loans and overdrafts, foreign-exchange services, card products and third party products offered by banks.

Money-laundering:
The concept of Money Laundering can be traced back to the "Hawala" transactions. Hawala mechanism facilitates the conversion of black money to white. Money laundering has become the centre of focus for criminals and governments alike.
As per sec.3 of Prevention of Money Laundering Act, 2002(PMLAct) money laundering has been defined as an offence. The main objective of this Act is to prevent, combat and control money laundering in India, and to confiscate, seize the property obtained from the laundered money. Money laundering is defined as the conversion of illegally acquired currency i.e. from drug trafficking, terrorist activity or other serious crimes as appearing to have been obtained from a legitimate source into legitimate funds. It is disguising of illegally obtained financial assets.

Sec.12 of the PMLAct requires every banking company, financial institution and intermediary to verify and maintain a record of all transactions of a prescribed value and to furnish information whenever sought within a prescribed time period. Under Section 35A of the Banking Regulation Act, 1949, Reserve Bank of India has issued guidelines to banking companies, financial institutions and intermediaries to maintain a record of all transactions. The RBI has said that every bank should set key indicators for accounts, taking note of the background of the customer, such as the country of origin, sources of funds, the type of transactions involved and other risk factors.

According to PML Act, 2002, whoever:

(a) Acquires, owns, possesses or transfer any proceeds of crime; or
(b) Knowingly enters into any transaction which is related to proceeds of crime either directly or indirectly; or
(c) Conceals or aids in the concealment of the proceeds of crime,

Relationship between BOD, COD, TOC and ThOD

For a completely biodegradable wastewater such as glucose, approximately ten percent of the original organics remain as non-biodegradable cellular residues after biological oxidation. Hence, the cellular residues are not measured by the BOD test. Therefore:
BODu = 0.9ThOD  ---1
where BODu = ultimate BOD
            ThOD = theoretical oxygen demand For domestic sewage and some biodegradable industrial wastes, the relationship between BOD5 and BODu is:
BOD5 = 0.77BODu  ---2
where BOD5 = 5 day BOD
            BODu = ultimate BOD
For most wastewaters:
ThOD = COD ---3
where ThOD = theoretical oxygen demand
COD = chemical oxygen demand since the COD test oxidizes all organics except for those which are totally resistant to dichromate oxidation.
Stoichiometrically, the COD/TOC ratio should be approximately the molecular ratio of oxygen to carbon:
COD/TOC =32/12= 2.66 ---4
The ratio will actually range from zero, when organic material is resistant to dichromate oxidation, to as much as 6.0 when inorganic reducing agents are present.
For raw domestic sewage and some biodegradable industrial wastes, the following ratio of BOD5/TOC occurs:
BOD5/TOC =32/12(0.90)(0.77) = 1.85 ---5
where BOD5 = 5 day BOD
TOC = Total Organic Carbon
0.90 = BOD5/BODu as per ---1
0.77 = BODu/ThOD as per ---2
              As a wastewater is oxidized through a wastewater treatment plant, the BOD5/TOC ratio will drop. A treatment plant effluent may have a BOD5 /TOC ratio of as low as 0.5 since the effluent wastewater is so much less biodegradable. (It has already been largely degraded).
              The BOD5 to COD ratio for domestic waste and certain biodegradable industrial wastes can be computed as follows:
BOD5 = 0.7 COD ---6
where BOD5 = 5 day BOD
              COD = chemical oxygen demand
                 0.7 = 1.85 /2.66
               1.85 = BOD5/TOC as per --5                2.66 = COD/TOC as per   --4
                 This ratio can also vary widely depending on the state of biodegradation of the wastewater. The author has found this ratio as low as 0.1 after several days of oxidation. If the BOD of a biodegradable wastewater equals zero, the wastewater will be completely biodegraded. There is some controversy about whether this ever occurs. Many authors will say that the Non-biodegradable Residue (NBDR) is as high as 0.10 as explained in the first paragraph of this section. The author has found that in activated sludge systems with hydraulic detention times in the range of 14 days, there is no accumulation of volatile suspended solids, which indicates that all organics are ultimately degraded under certain anoxic conditions.

12/01/2010 Good day!
The relationship between BOD and COD that your site gave is very useful!
I would like to know your reference book about this relationship, that is, the name of the book, its author, and its copyright date.
I would greatly appreciate your help.
Hoping to hear from you very soon.

With much hope and gratitude,
Liza

6/25/2011 I think that a typo error is present at the paragraph where it is written :

0.90 = BOD5/BODu as per ---1
0.77 = BODu/ThOD as per ---2
