Slee v Warke [1949] HCA 57

Slee v Warke [1949] HCA 57

Although there was a unilateral mistake by the appellants as to the option's terms, it was not contributed to by the respondent and did not cause hardship amounting to injustice. No concurrent intention existed for rectification, and no later agreement varying the deed was proven. Therefore, the respondent was entitled to the declaration of right regarding the option.
