However the courts do not wish to "make contracts for people", and so in Scammell and Nephew Ltd v Ouston, a clause stipulating the price of buying a new van as "on hire purchase terms" for two years was held unenforceable because there was no objective standard by which the court could know what price was intended or what a reasonable price might be.
但法庭并不希望“有意给人们制造合同”，所以在Scammell and Nephew Ltd v Ouston案里，规定以两年的租用为目的购买新货车的价格的条款就被认为是不可执行，因为没有客观的标准可以让法庭获知定价的意图或者应该如何定下合理的价格。
