JACKSON (AP) — The Louisiana Supreme Court has overturned a lower court ruling that forced a subsidiary of Entergy Corp. to pay back over $34 million to rate payers.

The ruling was made by Louisiana’s 4th Circuit Court of Appeals and has been highlighted in Mississippi Attorney General Jim Hood’s legal fight with Entergy.

Hood has filed a lawsuit claiming Entergy and its subsidiaries illegally manipulated the purchase and sale of electricity to maximize profits. The company has denied wrongdoing.

Entergy New Orleans was forced to make the $34 million payment after the appeals court overturned a ruling made by the New Orleans City Council, which determined the utility had overcharged customers there by $7.2 million, plus interest.

The appeals court had determined the city-ordered refund was too low.
