(33)The contracting parties should have the right to effect a standard termination of an open-end credit agreement. In addition, if agreed in the credit agreement, the creditor should have the right to suspend the consumer's right to draw down on an open-end credit agreement for objectively justified reasons. Such reasons may include, for instance, suspicion of an unauthorised or fraudulent use of the credit or a significantly increased risk of the consumer being unable to fulfil his obligation to repay the credit. This Directive does not affect national law in the area of contract law regulating the rights of the contracting parties to terminate the credit agreement on the basis of a breach of contract.
