With no. 15607/2012 decision of the Court of First Instance of Thessaloniki the execution of an order of payment of a bank against a company for the sale of medical supplies (our client) was suspended for a total amount of 2.951.496 €. The court considered abusive the termination of the loan agreement since the credit limit was not exceeded, no other order of payment was issued against the borrowing company and the bank’s claim, which ranged around 2/5 of the credit limit, was fully secured by bonds of the Greek State. The aforementioned decision ruled that the exercise of the rights of the bank vis-à-vis its clients should be governed by the principles of good faith and the users of commercial practices (Civil Code 178, 200, 288) which, due to their nature credit relationship as a lasting contractual relationship of particular trust between the parties – the duty of loyalty and the protection of the general interests of its clients so as to avoid any undue inconsistency that could damage the borrowers. Thus, in the event of a difficulty in fulfilling the benefit due to a financial weakness of the debtor exceeding the limits of that endurance, the bona fide performance of the benefit requires the lending bank to tolerate the deviation from the agreed and reasonable delay.
