Louisiana Supreme Court Opinions
Carollo v. Louisiana Dept. of Transportation & Development

Docket: 2021-C-01670
Opinion Date: September 9, 2022
Judge: John L. Weimer
Areas of Law: Civil Procedure, Government & Administrative Law, Personal Injury

Certiorari was granted in this case to resolve a split in the decisions of the Louisiana courts of appeal regarding the relationship between La. C.C.P. art. 425 and the res judicata statutes, La. R.S. 13:4231 and 13:4232. Particularly, the Supreme Court considered whether Article 425 was an independent claim preclusion provision apart from res judicata such that identity of parties was not required to preclude a subsequent suit, or whether Article 425 merely referenced the requirements of res judicata and thus a claim could not be precluded unless it was between the same parties as a prior suit. After reviewing the law and the arguments of the parties, the Louisiana Supreme Court found Article 425 functioned simply as a measure that put litigants on notice at the outset and, during the course of litigation, all causes of action arising out of the transaction or occurrence that is the subject matter of the litigation must be asserted. "Rather than have independent enforcement effect, Article 425 operates in tandem with and is enforced through the exception of res judicata. Because Article 425 is enforced through res judicata, all elements of res judicata–including identity of parties–must be satisfied for a second suit to be precluded."
