The article focuses on the “legitimate interest in performance” requirement which is now at the heart of the new test on penalty clauses but which has been left undefined by the Supreme Court in Cavendish Square Holding BV v Talal El Makdessi and ParkingEye Ltd v Beavis [2016]. It seeks to bring clarity to what is meant by “legitimate interest in performance” by examining other areas of the law of remedies for breach of contract where concepts of legitimate interest have featured in the court’s reasoning. It also makes suggestions as to what considerations are or might be relevant in determining whether a contracting party has a legitimate interest in performance, in particular a legitimate interest that goes beyond compensation.

刑罚法中的“合法利益”

这篇文章的重点是“履行中的合法利益”要求，该要求现在是惩罚条款新测试的核心，但最高法院在Cavendish Square Holding BV v Talal El Makdessi和ParkingEye Ltd v Beavis[2016]。它试图通过审查法律的其他违约救济领域，其中合法利益的概念已在法院的推理中体现出来，从而明确“履约中的合法利益”的含义。它还就在确定缔约方是否在履行方面具有合法利益，特别是超出补偿的合法利益时，哪些考虑是或可能相关提出了建议。
