There are several mechanisms available to those seeking to obtain guidance regarding compliance with Commission statutes, rules, regulations or orders or Commission-approved tariffs. The most formal, and most binding, form of guidance is provided through Commission orders, issued in response to pleadings subject to public review and comment. The least formal, and least binding, form of guidance is provided through the Enforcement Hotline (Hotline) and meetings and discussions with individual members of Commission staff. In between these two extremes are No Action Letter responses, legal opinions issued by the Office of the General Counsel, and interpretative letters issued by the Chief Accountant. While not binding on the Commission, these advisory materials provide confirmation of staff positions that reflect various levels of staff consensus.
