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". 

Opinion PER CURIAM.
PER CURIAM:
The petitioner and appellants in these cases contend that the Washington Metropolitan Area Transit Commission lacked jurisdiction to regulate their activities. The thesis underlying this claim is that the Commission is empowered to regulate only “transportation,” and the petitioners’ and appellants’ primary business is “sightseeing.” Although their sightseeing business involves transportation for hire, the petitioner and appellants argue that this transportation is only incidental to the sightseeing and so is not reachable by the Commission under the powers granted it by Congress.
Many cases of this Court have implicitly recognized that transportation operations which are tied to sightseeing operations are subject to the jurisdiction of the WMATC. See, e.g., Holiday Tours v. WMATC, 352 F.2d 672 (D.C.Cir.1965). Nothing in the law strips the WMATC of its jurisdiction simply because those providing transportation for hire are also in another business; the law looks only to whether transportation for hire is involved. Washington Metropolitan Area Transit Regulation Compact, D.C.Code § 1-2411 (1981 Ed.). The WMATC thus had jurisdiction in this case.
The other contentions of the petitioner and appellants are also without merit. For the foregoing reasons, the district court and WMATC decisions under challenge here are
Affirmed.
