A group of consumers are taking on Arizona Public Service (APS) in what has been described as a ‘David vs. Corporate Goliath’ battle. Stacey Champion, a single mom and small business owner, is at the forefront. She started a petition page on change.org and has also set up a crowd funded legal defense fund at fundedjustice.com to take on APS through a rehearing by the Arizona Corporation Commission (AZCC).
