The U. S Supreme Court back in April 2016 approved three changes to the Federal Rules of Civil Procedure. These approved changes are effective December 1, 2016. The changes are to rule 4 (which deals with the time within which a summons needs to be issued); rule 6 (which deals with counting response time for a due date of a pleading); and rule 82 (which removes reference to a statute which has been repealed).
Rule 82 simply removed the reference to 28 U.S.C. § 1392 when suggesting that admiralty or maritime claims under rule 9(h) are governed by that statute. 28 U.S.C. § 1392 has been repealed. The new statute which took the place of 28 U.S.C. § 1392 is U.S.C. § 1390. So, 28 U.S.C. § 1390 is now the the statute contained in rule 82.
