The National Labor Relations Board petitioned for enforcement of its order requiring the Shenandoah Brick & Tile Corp. to bargain with a union that had been certified following a representational election. 1 The company justified its refusal to bargain by asserting that certification was based upon an invalid election. Its principal complaint in this court is the board’s denial of a hearing on the charge that conduct attributed to the union rendered a fair election impossible.

After the election, the company filed objections which were overruled on the basis of the regional director’s investigation. We find no error of law or fact in the board’s determination chat the company did not raise substantial and material issues pertaining to the validity of the election. Consequently, a hearing on the company’s objections is unnecessary. Intertype Co. v. N. L. R. B., 401 F.2d 41 (4th Cir. 1968) ; N. L. R. B. v. Bata Shoe Co., 377 F.2d 821 (4th Cir.), cert. denied, 389 U.S. 917, 88 S.Ct. 238, 19 L.Ed.2d 265 (1967).

The Board’s order will be enforced.
