In a recent case decided in the Superior Court of California, Association of Irritated Residents vs. California Air Resources Board et al, a San Francisco County judge made a tentative ruling against the California Air Resources Board (CARB) ordering CARB to postpone the implementation of regulations to reduce greenhouse gas emissions, including the creation of a cap-and-trade system. The judge ruled that CARB failed to properly consider alternatives to a cap-and-trade system and that alternatives should have been presented to the public for comment. If the ruling is finalized, it could impact both future and existing greenhouse gas regulation in California. Pursuant to the rules governing court proceedings in California, both sides have 15 days from January 21, 2011, the date of judgement, to file objections to be considered by the Court prior to the issuance of the final order.
