Task: songer_casetyp1_7-2

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". 

PER CURIAM.
Plaintiff-appellant’s decedent met his death while doing construction work on defendant-appellee’s premises as the employee of a third party. Said third party had under agreement with the defendantappellee undertaken the installation of a major pipeline on which plaintiff-appellant’s decedent was working as a welder when the fatal accident occurred.
At trial the District Judge sustained a motion for a directed verdict in its favor made by defendant-appellee at the close of plaintiff-appellant’s case on the ground that as a matter of law no cause of action against the defendant-appellee had been established, and judgment for the defendant-appellee was entered. On this appeal from that judgment it is determined that the District Judge did not err in sustaining the motion for a directed verdict and the judgment is affirmed.
It will be observed that plaintiff-appellant has in effect had two opportunities to attempt to establish liability on the part of this defendant-appellee, an earlier judgment in its favor on its motion for summary judgment having been vacated and the cause remanded. Rogers v. Peabody Coal Company, 342 F.2d 749 (6th Cir. 1965).
