Substantive law includes contract law , tort law , and so on.
A procedural system provides the mechanism for applying substantive law to real disputes. A good procedural system ensures that similar cases will be treated similarly by the courts. The Plaintiff also has the initial burden of demonstrating he or she has a legitimate claim. In America, civil procedure usually takes the form of a series of rules and judicial practices. In federal courts, evidentiary rules are governed by the Federal Rules of Evidence.
