On April 16, a coalition of businesses and trade groups led by the Morning Star Packing Co. filed suit in the California Superior Court in Sacramento County against the California Air Resources Board (CARB) over the emissions cap-and-trade program’s greenhouse gas allowance auction. The coalition questioned whether CARB has the authority under the Global Warming Solutions Act of 2006 to host the auction and requested the auction be deemed an illegal tax. While all the plaintiffs excluding Morning Star Packing have not participated in an auction, they claimed these auctions have led to higher fuel and energy costs.
