Task: songer_casetyp1_7-3-1

What follows is an opinion from a United States Court of Appeals.
Your task is to identify the issue in the case, that is, the social and/or political context of the litigation in which more purely legal issues are argued. Put somewhat differently, this field identifies the nature of the conflict between the litigants. The focus here is on the subject matter of the controversy rather than its legal basis.
Your task is to determine the specific issue in the case within the broad category of "economic activity and regulation - taxes, patents, copyright". 

PER CURIAM.
In this ease, which was decided by this court on January 13, 1954, 209 F.2d 375, the defendant has filed a motion to recall and clarify the mandate of this court which reversed the judgment of the district court and remanded the cause with instructions to proceed in accordance with the opinion of this court. The district court in an opinion, 130 F.Supp. 691, filed April 18, 1955 rightly concluded that the issue, and the only one remaining in the case, to be tried on remand was whether the cable of acceptance of Fernseh, G.m.b.H., was sent prior to 1:10 P.M. (E.S.T.) in Washington, D. C., June 14, 1941, and hence prior to the effective time of Executive Order 8785. Under the mandate the defendant may not now assert, as he seeks for the first time to do, that the time of the completion of the contract is to be determined by the application of German law to be the time of the receipt of the cable of acceptance by the plaintiff instead of the time of its sending.
The motion will be denied.
