Task: songer_casetyp1_7-3-5

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 - misc economic regulation and benefits". 

ORDER
PER CURIAM.
Upon consideration of appellee’s motion for summary affirmance, as well as appellant’s motion to vacate and remand, and the response and reply thereto, it is
ORDERED by the Court that appellee’s motion for summary affirmance is denied. The passage of Pub.L. No. 97-447, 96 Stat. 2364 (January 12, 1983) (amending 36 U.S.C. § 1201 et seq.; to be codified at 36 U.S.C. § 1219), which exempts the United States Historical Society from paying, collecting or accounting “for any tax ... applicable to taxable events occurring within the United States Capital Building and grounds on or after January 1, 1964.” Id., has rendered the case moot. It is therefore
FURTHER ORDERED by the Court that the judgment of the District Court, 558 F.Supp. 213, is vacated and the case remanded to the District Court with directions to dismiss the complaint. See United States v. Munsingwear, 340 U.S. 36, 39, 71 S.Ct. 104, 106, 95 L.Ed. 36 (1950). It is
FURTHER ORDERED by the Court, sua sponte, that the Clerk withhold issuance of the mandate until seven days after disposition of any timely petition for rehearing. See Local Rule 14, as amended June 15, 1982.
