At a union representation election among employees of Leonard Creations of California, Inc., 62 employees voted in favor of representation, 61 voted against, and one ballot is contested. The contested ballot exhibits a full “X” in the box indicating a vote against union representation and a slash in the box in favor of it. 1 The National Labor Relations Board found the ballot invalid, and thus determined the election outcome in favor of unionization. Consequently, the Board certified the union as representative of the employees.

The company refused to bargain with the union, in order to obtain review in this court of the Board’s certification of the union. The Board petitioned to enforce its order to bargain, after finding that the company violated §§ 8(a)(5) and (1) 2 of the National Labor Relations Act by its refusal to bargain and by its unilateral grant of a wage increase. We reverse the Board.

While the NLRB has often held that marks in two alternative squares on a ballot render it invalid, see, e. g., Caribe Industrial and Electrical Supply, Inc., 216 N.L.R.B. 168 (1975); Bon Tool & Die Co., 115 N.L. R.B. 103 (1956), the underlying principle favors inclusion of a ballot in an election tally “where the voter’s intent has been clearly manifested,” NLRB v. Sauk Valley Manufacturing Co.„ 486 F.2d 1127, 1133 (9th Cir. 1973). This policy has often resulted in inclusion of ballots with marks in both squares. See, e. g., Abtex Beverage Corp., *113 237 N.L.R.B. 1271 (1978) (ballot counted where voter attempted to obliterate one mark); Belmont Smelting Works, 115 N.L.R.B. 1481 (1956) (complete “X” in one box validates ballot despite diagonal line in other box).

On review, an NLRB order will not be upheld unless supported by substantial evidence. NLRB v. Masonic Homes of California, 624 F.2d 88, 89 (9th Cir. 1980). In the present case, the entire record consists of the contested ballot. Examining the ballot in light of our prior decisions and those of the NLRB, we find little support for the Board’s conclusion that the voter’s intent was unclear. Although the “Yes” box contains a line, only the “No” box received a completed mark. It follows that the voter intended to register a “No” vote rather than a meaningless gesture of indecision.

The order of the Board is REVERSED.
