"It was common ground at trial that throughout the period the Bank's treatment of movements on overdrawn accounts (including Emerald's) was as follows: (1) If£1,000 was withdrawn (either in cash or on presentation of a cheque drawn on the account) on a Wednesday, the balance on the account was adjusted to reflect that withdrawal at the end of the day, and the interest to be charged for that day was calculated on the balance produced. The effect was that the customer paid interest on the£1,000 for the Wednesday. (2) If, on the following Monday,£1,000 was deposited to the credit of the account in cash or by means of a cheque drawn on AIB, the balance was adjusted on the same day to reflect that deposit, and the interest to be charged for that day was calculated on the balance produced. The effect was that the customer did not pay interest on the£1,000 for the Monday. (3) If the Monday deposit to the account was of a£1,000 cheque drawn on a bank other than AIB: (a) the overdrawn balance shown on the customer's statement would be adjusted on the Monday, and would therefore be reduced by£1,000 at the end of the day; (b) as a result of passing the cheque through the clearing system, the Bank would receive value from the bank upon which the cheque was drawn on the Wednesday; but (c) the balance on the customer's account at the Bank would not be adjusted 'for interest purposes' until the Thursday. This had the effect that the customer paid interest for the Wednesday ('the extra day') ..."
"2.1.7 My opinions reflect my understanding of the conditions and the policies generally adopted by the major clearing banks at the relevant time. With the exception of package lending, terms always have been negotiable. Both banker and borrower were entitled to negotiate the most beneficial rates deemed appropriate to the circumstances. ... 3.3.4 Cheques paid in at the account holding branch, drawn on another bank branch, take two business days to physically present to the appropriate branch of the paying bank. Credit is not given by A.I.B. for interest purposes until the third business day after paying in, ostensibly because cheques could be returned unpaid. Thus the fate of cheques is not truly known until business day three. Other London clearing banks operated similar clearing cycles to A.I.B., prior to 1994. Most major banks now operate a two business day clearing cycle."
"In my view, when a customer, particularly a business customer, enters into a business relationship with a bank, they must be accepted as doing so on the basis of the bank's standard terms, practices and conditions. If they are not prepared to do so, they can make enquiries as to the position, and they can, if they want to, negotiate different terms or decline to form any relationship with the bank. ... I find that when the parties entered into a relationship, they did so on the basis that, in so far as the terms and conditions were not expressly spelt out in the facility letters, they were on the bank's usual terms, conditions and practices, and one of those was the operation of the three day clearance cycle."
"The only proper conclusion which can be drawn, in the absence of any evidence that there was a different agreement between Mr Voller and the bank, is that the bank was granting him overdraft facilities at the standard rate for overdrafts"
"Even though they may appear immediately on your statement, you may incur interest charges and fees if you draw against uncleared cheques."
