In this Commission investigation, the Commission's Consumer Protection and Safety Division (CPSD) has the burden of establishing by a preponderance of the evidence that TracFone has committed the alleged violations. CPSD does not have the burden to refute defenses as the respondent assumes the burden of proof as to its defenses.7 This is the usual practice in Commission adjudicatory proceedings, including investigations.8 In applying the burden of proof to the parties in this proceeding, we consider the circumstances associated with affirmative defenses and the rule that, except as otherwise provided by law, a party has the burden of proof as to each fact the existence or nonexistence of which is essential to the claim for relief or defense that he is asserting.9 CPSD also filed a motion for summary adjudication.10 We review CPSD's motion for summary adjudication under a higher standard of review. A motion for summary adjudication essentially requires the Commission to determine whether the party bringing the motion prevails based solely on undisputed facts and on matters of law. The Commission treats such motions as a court would treat motions for summary judgment or summary adjudication in civil practice.11
