“It is a more or less universal rule that all reforms which are intended to simplify the law have unintended consequences. Section 2 of the Law of Property (Miscellaneous Provisions) Act 1989 came into force on 27th September 1989 – 23 years later, lawyers are still arguing about what contracts it does and does not affect, most recently in Keay v Morris Homes (West Midlands) Ltd [2012] EWCA Civ 900.”
Hardwicke Chambers, 2nd October 2012
