»The Risk of Breach of Contract. Unreasonable Risk to Performance in the General Law of Obligations«: The breach of a contractual obligation may be foreseeable in advance. The thesis deals with this risk to performance. Existing principles and standards of the general law of obligations are examined in order to explain how the risk to performance is to be predicted and why, in the event of an obvious risk to performance, the creditor may be entitled to cancel the contract or claim damages instead of performance.
