Louisiana Gov. Jeff Landry has suspended the state’s May 16 congressional primary following the U.S. Supreme Court’s April 29 action involving the state’s congressional map, setting off immediate consequences for election administration and renewed urgency in the underlying redistricting fight.

The move underscores a recurring reality in voting-rights litigation: court rulings do not stay confined to briefing schedules and appellate dockets.

The U.S. Supreme Court handed oil and gas defendants a meaningful procedural victory in long-running Louisiana coastal-damage litigation, unanimously holding that the companies may pursue a federal forum under the federal-officer removal statute when the challenged conduct is tied to wartime fuel production for the federal government. The ruling, covered in AP’s report on the decision, does not resolve the merits of the environmental claims.

In one of the most consequential election-law rulings of the term, the Supreme Court on April 29 struck down Louisiana’s congressional map, holding that the state’s SB8 plan was an unconstitutional racial gerrymander. The Court concluded that the Voting Rights Act did not require Louisiana to create an additional majority-minority district, and without that predicate, the state could not rely on compliance with federal voting-rights law as a compelling interest to justify race-based line drawing.

The decision in Louisiana, Appellant v. Phillip Callais, et al. immediately reshapes the legal landscape for redistricting disputes.

The U.S. Supreme Court on April 17, 2026 handed Chevron a significant procedural victory in long-running Louisiana coastal-damage litigation, unanimously ruling that the company may pursue removal to federal court in a major suit brought by Plaquemines Parish. The decision does not resolve the merits of the parish’s land-loss and environmental damage claims, but it strengthens a key defense strategy in a wave of cases targeting oil and gas operators for decades of coastal erosion and wetlands degradation.

The case, Chevron USA Incorporated, et al., Petitioners v. Plaquemines Parish, Louisiana, et al., has been closely watched because Louisiana’s coastal suits have produced enormous exposure risk.
