April 17 (UPI) -- The Supreme Court ruled unanimously in favor of Chevron in a case related to damage to wetlands in Louisiana that dates to World War II.

The case was brought more than a decade ago and relates to damage allegedly done when Chevron's corporate predecessors were refining aviation gas on behalf of the federal government during the war, Scotusblog and The Washington Post reported.

The 8-0 ruling sent the federal lawsuit back to a lower court in a move that could jeopardize a $745 million ruling against the company to restore the wetlands, as well as other similar cases with fossil fuel companies before courts in the United States.

Parishes in Louisiana filed the case with the help of state officials against oil and gas companies refining crude oil along the coast during the war, claiming that proper permits were never obtained for their work and that they had not followed "prudent industry practices."
