Roman Dutch contract law

In keeping with Enlightenment values, natural lawyers stripped away the Christian morality from contract law. They redefined a contract as a concurrence of wills, and each party's "promise" was now seen as a declaration of will devoid of moral obligation (will theory). In place of iusta causa developed a general principle of binding force under which any valid contract was both binding and actionable. Canonist substantive fairness shifted to procedural fairness, so good faith and mutual assent were retained as requirements, but just price and laesio enormis were not. In African states which were previously under English or South African rule, public policy was substituted for bonos mores, though this shift did not affect other Roman-Dutch law jurisdictions.
