The purpose of the decision review process is to assure complete, accurate, consistent and uniform decisions and the furtherance of public safety. Criteria for disapproval of a decision include a determination by the board that the panel made an error of law, or that the panel's decision was based on an error of fact, or that new information should be presented to the board, any of which when corrected or considered by the board, has a substantial likelihood of resulting in a substantially different decision upon a rehearing. In deciding if a decision should be approved, board staff shall review the information available to the panel that made the decision and any information received as provided in § 2028.
