In the event the commission exercises its rulemaking authority in a manner that is beyond purpose and intent of this compact, or the powers granted hereunder, then the action by the commission shall be invalid and have no force and effect of law in the member states.
3. (c) If a majority of the legislatures of the member states rejects a rule, by enactment of a statute or resolution in the same manner used to adopt this compact within four years of the date of adoption of the rule, then the rule shall have no further force and effect in any member state.

   1. (1) Meet an imminent threat to public health, safety, or welfare.
   2. (2) Prevent a loss of commission or member state funds.
