*612In Staunton Fuel, the National Labor Relations Board established that a contract between a union and an employer can overcome the presumption that a construction-industry bargaining relationship is governed by section 8(f) of the National Labor Relations Act, 29 U.S.C. § 158(f), rather than section 9(a), id. § 159(a), if the contract’s language “unequivocally indicates that (1) the union requested recognition as the majority or 9(a) representative of the unit employees; (2) the employer recognized the union as the majority or 9(a) bargaining representative; and (3) the employer’s recognition was based on the union’s having shown, or having offered to show, evidence of its majority support,” In re Staunton Fuel & Material, Inc., 335 N.L.R.B. 717, 720 (2001). The Board applied the Staunton Fuel test, and the appellant Union does not dispute that it provides the dispositive legal standard, so we assume its applicability here.

G & L Associated, Inc., d/b/a USA Fire Protection (“USA Fire”), a company that installs building sprinklers, and Road Sprinkler Fitters Local Union No. 669, U.A., AFL-CIO (“the Union”) entered into a collective bargaining agreement that says the following:

The employer executing this document below has, on the basis of objective and reliable information, confirmed that a clear majority of the sprinkler fitters in its employ are members of, and are represented by Road Sprinkler Fitters Local Union No. 669, U.A., AFL-CIO, for purposes of collective bargaining.

The employer therefore unconditionally acknowledges and confirms that Local Union 669 is the exclusive bargaining representative of its sprinkler fitter employees pursuant to Section 9(a) of the National Labor Relations Act.

G&L Associated, Inc. d/b/a USA Fire Protection, 358 N.L.R.B. No. 162 (2012).

The Board found that this language failed to satisfy the third Staunton Fuel requirement. -We agree. Although the contract indicates that USA Fire had evidence that a majority of the relevant employees were “represented by” the Union and were “members of’ the Union, Staun-ton Fuel expressly holds that such evidence is insufficient to satisfy the third requirement:

[W]ith respect to the union’s claim of majority support, there is a significant difference between a contractual statement that the union “represents” a majority of union employees — which would be accurate under either an 8(f) or a 9(a) agreement — and a statement to the effect that, for example, the union “has the support” or “has the authorization” of a majority to represent them. Similarly, a provision stating only that a majority of unit employees “are members” of the union would be consistent with a union security obligation , under either an 8(f) or a 9(a) relationship and is therefore insufficient to confirm 9(a) status.

Staunton Fuel, 335 N.L.R.B. at 720 (internal citation omitted).

None of the Union’s three arguments to the contrary is convincing. First; it cites cases predating Staunton Fuel that found evidence of majority membership or representation sufficient to establish a 9(a) agreement and argues that such evidence remains sufficient. But Staunton Fuel expressly stated that such evidence is no longer adequate and overruled its prior cases that relied on majority membership: “[t]o the extent that any of our ... cases may be read to imply that an agreement indicating that the union ‘represents a majority’ or has a majority of ‘members’ in the unit, without more, is independently sufficient to establish 9(a) status, those cases are overruled.” Id.

*613Second, it asserts that express contractual language indicating the parties’ intent to form a 9(a) agreement overcomes any need to have evidence of majority support. Staunton Fuel is clear, however, that to overcome the 8(f) presumption, contractual language must demonstrate both party intent to form a 9(a) relationship and evidence of majority support.

Third, the Union asserts that the Board’s decision in this case conflicts with prior decisions in which the Board concluded that similar Union contracts established 9(a) agreements. In those cases, however, the contracts stated that the employer had information confirming that a majority of the relevant employees “ha[d] designated” the Union “for purposes of collective bargaining,” e.g., Triple A Fire Protection, Inc., 312 N.L.R.B. 1088, 1088 (1993), a critical distinction because such language may provide what is missing here: evidence of majority authorization.1

The Union finally asserts that section 10(b) of the Act, which bars challenges to the validity of a 9(a) agreement more than six months after the agreement begins, see Raymond F. Kravis Center for Performing Arts, Inc. v. NLRB, 550 F.3d 1183, 1189-90 (D.C.Cir. 2008), prevented USA Fire from asserting that the contract established a section 8(f) agreement. We have previously rejected this exact argument, explaining that it “begs the question” because “[t]he fundamental issue ... is whether the ... contract was subject to section 8(f) or 9(a).” Nova Plumbing, Inc. v. NLRB, 330 F.3d 531, 539 (D.C.Cir. 2003); accord Brennan Sand & Gravel Co., 289 N.L.R.B. 977, 979 (1988). Because the contract established only a section 8(f) agreement, section 10(b) does not apply.
