procedural law, Law that prescribes the procedures and methods for enforcing rights and duties and for obtaining redress (e.g., in a suit). It is distinguished from substantive law (i.e., law that creates, defines, or regulates rights and duties). Procedural law is a set of established forms for conducting a trial and regulating the events that precede and follow it. It prescribes rules relative to jurisdiction, pleading and practice, jury selection, evidence, appeal, execution of judgments, representation of counsel, costs, registration (e.g., of a stock offer), prosecution of crime, and conveyancing (transference of deeds, leases, etc.), among other matters.
