December 1 has come and gone, and Congress took no action to stop the new, "restyled" Federal Rules of Civil Procedure from coming into effect. Every rule in the newly-effective FRCP's has changed. The substance of most rules has stayed the same, but all of the rules have changed stylistically (that's why they're calling it a "restyling"). Cornell's Legal Information Institute offers free access to the new rules here. And if a particular subsection you are looking for has moved, this chart may be able to help you find it.
