Court rules provide the parties with information and instructions on matters pertaining to judicial proceedings. They establish uniform procedures such as filing deadlines, proper formatting, delivery method, timing, etc. and they aid the court in performing its business.
You can find some court rules in your annotated code. This is very useful because it allows you to pick up journals and cases discussing those rules. Some treatises reprint court rules as well as provide analysis and explanation of them. Most court websites also provide their court rules.
A useful tip is to look at the structure of litigation. The rules are generally listed in the order that litigation occurs. You can safely divide rules up into pre-trial, trial, post-trial, and appellate. You’ll have rules of civil procedure, rules of criminal procedure, rules of evidence, and appellate rules.
