There can be no question, at least none is here raised, but that the Price Control Extension Act of 1946 effectually extended the Emergency Price Control Act of 1942 to June 30, 1947. “Congress may revive or extend an act by any form of words which makes clear its intention so to do.” Kersten v. United States, 10 Cir., 161 F.2d 337, 338. That such was its intent is abundantly clear, and this is demonstrated in the language thereof. “Sec. 17. This Act may be cited as the ‘Price Control Extension Act of 1946.’ ” Section 18 in part provides: “(1) The provisions of this Act shall take effect as of June 30, 1946, and (2) all regulations, orders, price schedules, and requirements under the Emergency Price Control Act of 1942, as amended * * *, and the Stabilization Act of 1942, as amended, which were in effect on June 30, 1946, shall be in effect in the same manner and to the same extent as if this Act had been enacted on June 30, 1946, * * *: Provided further, That no act or transaction, or omission or failure to act, occurring subsequent to June 30, 1946, and prior to the date of enactment of this Act shall be deemed to be a violation of the Emergency Price Control Act of 1942, as amended, or the Stabilization Act of 1942, as amended, or of any regulation, order, price schedule, or requirement under either of such Acts: * * 50 U.S.C.A.Appendix, § 901a note. It is equally plain that Congress intended to make such Acts and the regulations promulgated thereunder retroactive to June 30, 1946, with the proviso that there should be no civil or criminal liability for any act, transaction, omission, or failure to act occurring subsequent to June 30, 1946, and prior to July 25, 1946. Porter v. Shibe, 10 Cir., 158 F.2d 68.
