New Orleans City v. Aspect Energy, No. 24-30199 (5th Cir. 2025)
Annotate this Case
The City of New Orleans filed a lawsuit against several pipeline operators and Entergy New Orleans LLC, alleging that their oil and gas production and transportation activities caused damage to the City's coastal zone. The City claimed that Entergy allowed its pipeline canals to widen and erode, threatening the City's storm buffer. The lawsuit was filed under Louisiana’s State and Local Coastal Resources Management Act of 1978 (SLCRMA).
The defendants removed the case to federal court, arguing that Entergy, the only in-state defendant, was improperly joined to defeat diversity jurisdiction. Entergy consented to the removal and argued that it was exempt from SLCRMA’s permit requirements because its activities commenced before the statute's effective date. The City moved to remand the case to state court, but the United States District Court for the Eastern District of Louisiana denied the motion, dismissed Entergy as a party, and stayed the case pending appeal.
The United States Court of Appeals for the Fifth Circuit reviewed the case and affirmed the district court's judgment. The appellate court held that Entergy was improperly joined because its activities were exempt under SLCRMA’s Historical-Use Exception, which applies to uses legally commenced before the statute's effective date. The court found no reasonable basis for the City to recover against Entergy, thus disregarding Entergy's citizenship and establishing complete diversity among the parties. The court also rejected the City's argument that it was merely a nominal party representing Louisiana, concluding that the City filed the suit on its own behalf and stood to benefit from a favorable ruling. Consequently, the appellate court affirmed the district court's denial of the City's motion to remand.
