What is satisfactory quality?
This is the definition used in the Sale and Supply of Goods Act 1994 as the legitimate reason for a purchaser to reject goods sold by a supplier. The 1994 Act modified the Sale of Goods Act 1979 that defined the reason for rejection as not being of “merchantable quality”. The later Act should have made life a lot easier for all of us, but didn’t (Britain being Britain and lawyers being lawyers). We are forced to rely on case law precedents as to what constitutes “satisfactory quality” and what doesn’t. Even where a precedent is set, it can be overruled by a higher authority, so every court case involving the Sale and Supply of Goods Act 1994 involves legal argument on the technicalities as to whether a previous judgement sets a precedent for the case being heard. Broadly, you probably won’t be able to reject a car you have owned for more than six months, you won’t be able to reject it for a trivial reason and, most importantly, the only way to start the proceedings is to return the car
