Cal. Sts. & High. Code § 5422

The court in which an action for the recovery of an assessment is commenced shall have power to adjudge and decree a lien against the premises assessed, and to order such premises to be sold on execution, as in other cases of the sale of real estate by the process of the courts. On appeal, the appellate courts shall be vested with the same power to adjudge and decree a lien and to order such premises to be sold on execution or decree as is conferred on the court from which an appeal is taken.
