If the decision of the Water Resources Commission requires the cancellation of a permit, then the commission shall at once cancel, or have canceled, the permit. Thereafter the permit shall be of no further force or effect, and shall not be recognized or admitted as evidence of any right or interest in or to the waters covered by it in any proceeding in the courts or before other tribunals of the state. Permits having subsequent priority shall upon such cancellation have priority in the order of the filing of the applications upon which subsequent permits are based, as if the canceled permit, or the application upon which it was based, had never existed. [Amended by 1985 c.673 §43]
