The Soviet parliament Monday removed the final hurdle to ratification of the intermediate-range missile treaty, but a top official said the Kremlin should not formally commit itself to the pact before the U.S. Senate does.

Members of the foreign affairs commissions of the two chambers of the Supreme Soviet met in joint session to unanimously endorse the treaty and send it to the Presidium for ratification.The joint meeting, attended by some 20 Supreme Soviet deputies and presided over by Yegor K. Ligachev, the No. 2 Kremlin leader, culminated a process that began Feb. 9 when Foreign Minister Eduard A. Shevardnadze appeared before lawmakers to endorse the treaty.

By approving ratification of the pact, the two foreign affairs committees set the stage for final action by the Presidium, the Supreme Soviet body that by law must ratify such international agreements.
