The Fundamentals of Criminal Law in Australia Criminal law includes both substantive and procedural elements. In general, the substantive component consists of defining and comprehending the essential aspects of numerous common law and statutory crimes, as well as the relevant defences. The procedural component, on the other hand, refers to the enforcement mechanism, or, to put it another way, the procedure by which criminal defendants are brought to court and tried for their claimed breaches. Arrest, search and seizure, illegally obtained evidence, pleadings, double jeopardy, arraignment, jury selection, and sentencing rules, for example, constitute only a portion of the procedural component of criminal law. To give credit to such a big and intricate subject, it should be obvious that a separate and lengthy law would be required.
