If a contractor or subcontractor asserting a use or release restriction submits to the contracting officer a written request, showing the need for additional time to comply with the requirement to justify the current validity of the asserted restriction, additional time to adequately permit the submission of such justification shall be provided by the contracting officer as appropriate.

If a party asserting a restriction receives notices of challenges to restrictions on technical data from more than one contracting officer, and notifies each contracting officer of the existence of more than one challenge, the contracting officer initiating the first in time challenge, after consultation with the party asserting the restriction and the other contracting officers, shall formulate a schedule of responses to each of the challenges that will afford the party asserting the restriction with an equitable opportunity to respond to each such challenge.
