Paterson v McNaghten

The case of *Paterson v McNaghten* concerned a dispute between a husband and wife arising from a separation deed. The central issue revolved around the revocability of the contract, particularly in light of a restraint on anticipation clause, and whether a condition precedent had been waived, leading to an accord and satisfaction. The matter was heard by Griffith C.J., Barton and O'Connor JJ.

The court was required to determine the legal effect of the separation deed, specifically whether the restraint on anticipation rendered the contract irrevocable. Furthermore, the court had to consider whether the wife had waived a condition precedent within the deed and if this waiver constituted an accord and satisfaction, thereby binding the parties to the agreement.

The judges reasoned that the restraint on anticipation, as contained within the separation deed, did not operate to make the contract irrevocable. They found that the wife's actions demonstrated a clear intention to waive the condition precedent. This waiver, in turn, was held to amount to an accord and satisfaction, meaning the parties had reached a final agreement and settled their dispute, rendering the deed binding and enforceable.
