Because rules cannot adequately anticipate all potential specific factual situations and circumstances presented for action, determination, or adjudication by the commission, the nature of the action taken with regard to any matter or the disposition of any matter pending before the commission is not necessarily of meaningful precedental value. The commission shall not be bound by the precedent of any previous action, determination, or adjudication in the subsequent disposition of any matter pending before it.
