PDF Version: Unilateral Mistake in Integration: When is Rectification an Appropriate Remedy?
Case commented on: Johnson v Moody, 2014 ABQB 80
A written contract may be executed by the parties on the basis of a unilateral mistake as to a term or terms of the contract. For example, the parties may reach an oral agreement but the terms of the oral agreement may not be accurately recorded in the written contract signed by the parties. This type of mistake, usually referred to as ‘mistake in integration’, may be remedied by an order of rectification particularly where the non-mistaken party’s attempt to take advantage of the written contract would amount to fraud or the equivalent of fraud. As discussed subsequently, a mistake in integration occurred in Johnson v. Moody, a recent decision of the Court of Queen’s Bench of Alberta.
