Within the time frame specified in Mhp 208.16(b), the board, on its own motion may reconsider, revise or reverse any final order. No reconsideration by the board shall occur unless the board finds that a relevant rule, point of law or fact has been overlooked or misapprehended. If, upon reconsideration, the board takes action based upon the existing record, prior notice shall not be given to the parties. If further argument or data should be considered before making such an order, the board shall provide the parties with notice and an opportunity to be heard before any final revision is made in the board's previous order.
