Magnesium Casting Co. v. NLRB, 401 U.S. 137 (1971)

Magnesium Casting Co. v. National Labor Relations Board

No. 370

Argued January 119, 1971

Decided February 23, 1971

401 U.S. 137

Syllabus

Following a unit determination hearing, the National Labor Relations Board (NLRB) regional director concluded that three individuals were employees, rather than supervisors, and thus includible in the proposed bargaining unit at petitioner company's plant. The NLRB denied petitioner's request for review. Following an election, the regional director certified the union as the exclusive bargaining representative. Subsequently, the NLRB upheld a finding that petitioner's refusal to bargain constituted an unfair labor practice. Petitioner moved for reconsideration on the ground that the NLRB was required to give plenary review to the regional director's representation determination before issuing an unfair labor practice order based on that determination. The motion was denied, and the Court of Appeals enforced the NLRB's order.

Held: Under § 3(b) of the National Labor Relations Act, the NLRB is permitted to delegate to the regional director its authority to determine the appropriate bargaining unit, and plenary review by the NLRB of such determination is not mandatory. Pp. 141-143.

427 F.2d 114, affirmed.

DOUGLAS, J., delivered the opinion for a unanimous Court.
