Emergency rule, regulation, or order

In the event an emergency is found to exist by the commission which in its judgment requires the making, revoking, amending, modifying, altering, enlarging, renewing, or extending of a rule, regulation, or order without first holding a hearing after due notice, such emergency rule, regulation, or order shall have the same validity as if a hearing after due notice with respect to the same had been held. The emergency rule, regulation, or order permitted by this section shall remain in force no longer than fifteen days from its effective date. It shall expire when the rule, regulation, or order made after due notice and hearing with respect to the subject matter of the emergency rule, regulation, or order becomes effective. In no event shall the emergency rule, regulation, or order remain in effect longer than fifteen days.
