What follows is an opinion from a United States Court of Appeals. Your task is to identify what party initiated the appeal. For cases with cross appeals or multiple docket numbers, if the opinion does not explicitly indicate which appeal was filed first, assumes that the first litigant listed as the "appellant" or "petitioner" was the first to file the appeal. In federal habeas corpus petitions, consider the prisoner to be the plaintiff.

Opinion:
NATIONAL LABOR RELATIONS BOARD, Petitioner, v. MIDWAY CLOVER FARM MARKET, INC., Respondent.

United States Court of Appeals, Sixth Circuit.

ORDER
This case is before the court upon the application of the National Labor Relations Board to enforce its order reported at 175 N.L.R.B. No. 151. Reference is made to the decision and order of the Board for a recitation of the facts.
This court holds that the part of the order requiring reinstatement of Stewart Prindle with backpay is not supported by substantial evidence on the record when considered as a whole, for the reasons stated in the opinion of the trial examiner and the dissenting opinion of Chairman McCulloch.
It is ordered that enforcement is denied as to that part of the Board’s order requiring the reinstatement of Stewart Prindle with backpay. It is further ordered that in all other respects enforcement is granted.
Judge McCree would enforce the order of the Board in its entirety.
