ex-parte, a provisional increase,

What must be stressed is that while under Executive Order No. 172, a hearing is indispensable, it does not preclude the Board from ordering, ex-parte, a provisional increase, as it did here, subject to its final disposition of whether or not: (1) to make it permanent; (2) to reduce or increase it further; or (3) to deny the application. Section 3, paragraph (e) is akin to a temporary restraining order or a writ of preliminary attachment issued by the courts, which are given ex-parte and which are subject to the resolution of the main case.
