If you live in one of ten Southern California counties and purchased gas between February 20, 2015 and November 10, 2015 (or live out of state or on behalf of a business between February 18, 2015 and May 31, 2017) you might be eligible for a class action rebate. The counties are: Los Angeles, San Diego, Orange, Riverside, San Bernardino, Kern, Ventura, Santa Barbara, San Luis Obispo, and/or Imperial.
It was alleged that gas trading firms participated in market manipulation and price gouging. They admit no wrong doing but have agreed to a $50 million settlement. You must submit a claim by January 10, 2025. The official website is: https://calgaslitigation.com/.
As always with these settlements you might as well participate unless you plan to file your own legal action.
