In selecting matters for his attention, the Public Counsel shall address himself particularly to an administrative act that might be:
(1) Contrary to law or regulation;
(2) Unreasonable, unfair, oppressive, or inconsistent with the general course of an administrative agency's judgments;
(3) Mistaken in law or arbitrary in ascertainments of fact;
(4) Improper in motivation or based on irrelevant considerations;
(5) Unclear or inadequately explained when reasons should have been revealed; or
(6) Inefficiently performed.
The Public Counsel may concern himself also with strengthening procedures and practices which lessen the risk that objectionable administrative acts will occur.
