Task: songer_amicus

What follows is an opinion from a United States Court of Appeals.
Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
Your task is to determine or not there was any amicus participation before the court of appeals.

ORDER
PER CURIAM.
These causes came on to be heard on petitions for review and cross-application for enforcement of an order of the National Labor Relations Board and were argued by counsel. While the issues presented occasion no need for an opinion, they have been accorded full consideration by the court. See Local Rule 13(c).
The order of the National Labor Relations Board is supported by substantial evidence in the record- taken as a whole. See Universal Camera Corp. v. NLRB, 340 U.S. 474, 71 S.Ct. 456, 95 L.Ed. 456 (1951). Moreover, this court finds that the Board’s order is otherwise free from reversible legal error.
On consideration of the foregoing, generally for the reasons stated in the Board’s order, it is ORDERED and ADJUDGED by this court that the petitions for review are hereby denied and the cross-application for enforcement is hereby granted.
MARKEY, Chief Judge, dissents from the foregoing order for the reasons stated in the following dissenting opinion.
