A Louisiana flood board is nearing a deadline for asking the U.S. Supreme Court to review its lawsuit seeking to make oil and gas companies pay for decades of damage to coastal wetlands.

Federal district and appeals courts have rejected the lawsuit, which was met by fierce opposition from the energy industry and many in state government when it was filed in 2013. The suit by the Southeast Louisiana Flood Protection Authority East said drilling and dredging activity contributed to loss of wetlands that form a hurricane buffer for New Orleans.

Oil industry supporters have labeled the lawsuit an attack on a vital industry. Tuesday marks the deadline for the flood board attorneys to seek Supreme Court review after their last defeat in April.

A federal district judge's 2015 ruling held that federal and state law provided no avenue by which the board could bring the suit.

A three judge panel of the 5th U.S. Circuit Court of Appeals upheld the ruling in March and the full 15-member court refused a rehearing in April. Lawyers for the flood board had a 90-day window to seek Supreme Court review.

Flood authority lawyers have argued that the flood board has the right to seek compensation for levee damage under the federal Rivers and Harbors Act. They also argued that federal judges should not have allowed the case to be moved to federal court from the state court where it originally was filed.

Meanwhile, some coastal parishes are pursuing coastal damage suits in state courts on different legal grounds. Gov. John Bel Edwards, a Democrat, has urged the energy companies to work toward a settlement. Industry leaders have resisted, saying the suits are meritless.
