A statute suggests that a particular tribunal is inquisitorial rather than adversarial if it refers to the decision-making process as an "inquiry" rather than a "hearing"; says the tribunal "may" hold a hearing or inquiry rather than "shall" hold one; gives the tribunal power to collect evidence independently of the parties; requires the tribunal to determine what constitutes the public interest or what is necessary to protect public health or ensure public safety, rather than to resolve a dispute between individuals about property or money; or requires that the adjudicators have special expertise in the subject matter.
