Except as provided in this act, the decision of the administrative

law judge shall be final as to all questions of fact and law. The

decision of the administrative law judge shall be issued within

thirty (30) days following the submission of the case by the

parties. The power and jurisdiction of the Commission over each

case shall be continuing and it may, from time to time, make such

modifications or changes with respect to former findings or orders

relating thereto if, in its opinion, it may be justified.

B. In addition to the duties set forth in this section, the

administrative law judges shall have the following duties and

and determinations as may be required by any rule or judgment of the
