(a) In addition to any other delegation powers granted to the director under law, the director may delegate his or her powers to adopt final decisions under this chapter to all administrative law judges within specified ranges in the department, in the types of cases deemed appropriate by the director. The authority to adopt final decisions shall not be contingent upon the outcome of the judge’s resolution of the case or issue, nor upon the identity of a particular administrative law judge. The defined areas of delegation shall be published by the department after interested groups such as the Coalition of California Welfare Rights Organizations, legal aid societies, and the County Welfare Directors Association have had a reasonable amount of time to review and comment.
(b) Notwithstanding any other provisions of this chapter, decisions rendered by the administrative law judges under the authority of this section shall be treated, for all purposes, as the decision of the director.
