Opinion for the Court filed by Circuit Judge WILLIAMS.
Under a labor agreement governing construction work at a refinery jobsite in California, Steamfitters Local Union No. 342 held an exclusive right to dispatch workers to subcontractor Contra Costa Electric. Petitioner Joe Jacoby, a member of the union for 27 years, registered for employment through the union’s hiring hall; due to his skills and experience, his name was placed on the highest priority “A” list. For a period the union mistakenly dispatched several lower-priority individuals ahead of Jacoby. On discovery of the error, it dispatched Jacoby. All parties agree, for current purposes at least, that the priority mix-up was merely negligent, and reflected no intentional wrongdoing.
Jacoby filed an unfair labor practice charge with the National Labor Relations Board, and the Board’s General Counsel issued a complaint. After a hearing an administrative law judge found that the union’s negligent deviation from established hiring hall rules breached its duty of fair representation and thereby violated §§ 8(b)(1)(A) & (2) of the National Labor Relations Act as amended (the “NLRA”), 29 U.S.C. § 158(b)(1)(A) & (2).
Steamfitters Local No. 812 (Contra Costa Electric),
329 N.L.R.B. No. 65, slip op. at 10-12 (Dec.5, 1995). The Board reversed, ruling that the union’s negligence violated neither the duty of fair representation nor the Act.
Steamfitters Local No. 812 (Contra Costa Electric),
329 N.L.R.B. No. 65,
We have held that the Board’s interpretation of the duty of fair representation is entitled to deference under
Chevron, U.S.A., Inc. v. NRDC,
In addition, the Board’s conclusion that the union’s negligence did not independently violate the Act is, as we explain below, intertwined with the issue of the duty of fair representation. Accordingly, we find that it would be premature to rule on it before the Board has had an opportunity to revisit the question on remand. * * *
The duty of fair representation originated in the context of the Railway Labor Act, judicially inferred from that statute and enforceable in the courts. See
Steele v. Louisville & Nashville R.R. Co.,
Originally, the duty was the exclusive province of the courts, falling within the federal courts’ general federal question jurisdiction. See
Syres v. Oil, Chemical and Atomic Workers Local 23,
At the same time, the Supreme Court refused to find that the Board’s enforcement of the duty of fair representation preempted judicial jurisdiction over the duty of fair representation inferred from the NLRA.
Vaca v. Sipes,
And it is important to emphasize that for these court adjudicated cases the
Board’s
definition of the duty of fair representation for purposes of adjudicating unfair labor practices appears only marginally relevant. The Supreme Court in
Breininger
explicitly “rejectfed] the proposition that the duty of fair representation should be defined in terms of what is an unfair labor practice.”
The duty of fair representation clearly extends to a union’s operation of an exclusive hiring hall. See
Breininger,
[A]ny departure from established exclusive hiring hall procedures which results in a denial of employment to an applicant falls within that class of discrimination which inherently encourages union membership, breaches the duty of fair representation owed to all hiring hall users, and violates Section 8(b)(1)(A) and (2) [of the NLRA], unless the union demonstrates that its interference with employment was pursuant to a valid union-security clause or was necessary to the effective performance of its representative function.
Boilermakers Local No. 374 v. NLRB,
No specific intent to discriminate on the basis of union membership or activity is required; a union commits an unfair labor practice if it administers the exclusive hall arbitrarily or without reference to objective criteria and thereby affects the employment status of those it is expected to represent. “By wielding its power arbitrarily, the Union gives notice that its favor must be curried, thereby encouraging membership and unquestioned adherence to its policies.”
Id.
(quoting
NLRB v. International Ass’n of Bridge, Structural & Ornamental Iron Workers, Local 133,
The Board itself, applying the standard that we upheld in
Boilermakers,
found a breach of the duty (and an unfair labor practice) in circumstances virtually identical to the present ones. In
Iron Workers Local 118 (California Erectors),
In reversing the ALJ, the Board here acknowledged that her reading of that case was “correct,” but found that continued application of
California Erectors
would be inconsistent with the Supreme Court decisions in
United Steelworkers of America v. Rawson,
There is undoubtedly language in these Supreme Court decisions supporting the Board’s view. Both explicate the standard earlier laid down by the Court in
Vaca v. Sipes,
O’Neill
involved a claim that the Air Line Pilots Association breached its duty of fair representation in its negotiation and acceptance of a strike settlement. The Court held that the
Vaca
standard “applies to all union activity, including contract negotiation.”
Neither Rawson nor O’Neill specifically concerned the duty owed by a union when it operates an exclusive hiring hall. In its decision here, however, the Board reasons that the two cases, read together, mandate that merely negligent conduct can never breach the duty of representation in any context, including that of the hiring hall. See Board Decision, 329 N.L.R.B. No. 65, slip op. at 2.
But as Jacoby points out, the Board’s reading of
Rawson
and
O’Neill
cannot be reconciled with our decision in
Plumbers & Pipe Fitters.
There we considered and rejected the argument that
O’Neill
undermined the standard governing a union’s operation of an exclusive hiring hall — specifically the principle that a union operate a hiring hall by “reference to objective criteria.”
In support of this conclusion we relied on the drastic difference in context. In
O’Neill
the Court’s focus was on “protecting the content of negotiated agreements from judicial second-guessing.”
Id.
The operation of a hiring hall, by contrast, was one “where the union has assumed the role of employer, as well as representative, and where the risk of judicial second-guessing of a negotiated agreement that was of such concern to the Court in
O’Neill
is simply not present.”
Id.
We also relied on the Supreme Court’s decision in
Breininger,
issued only one year before
Rawson
and two years before
O’Neill,
where the Court said that the imbalance of power and possibilities for abuse created by union operation of a hiring hall were such that “if a union does wield additional power in a hiring hall by assuming the employer’s role, its responsibility to exercise that power fairly
increases
rather than
decreases.” Breininger,
In its decision here, the Board sought to reconcile Breininger’s statement that “additional power” entailed increased responsibility with its interpretation of Rawson and O’Neill. It reasoned that in Breininger the Court was merely rejecting the argument that the duty of fair representation did not apply at all in the hiring hall context and had meant the language about a union’s increased responsibility not to refer to any heightened degree of duty, but merely to the fact that a union “takes on additional responsibilities” when it operates a hiring hall. Board Decision, 329 N.L.R.B. No. 65, slip op. at 2. Nothing in the surrounding language in Breininger lends support to this theory.
*617
The question before us today differs from that in
Plumbers & Pipe Fitters
primarily with regard to two details, both ultimately insignificant. First, this case turns on a different aspect of the legal standard defined in
Boilermakers.
Whereas
Plumbers & Pipe Fitters
involved the operation of a hiring hall “without reference to objective criteria,” see
Boilermakers,
In addition, one might argue that in the present context the
Boilermakers
standard is more vulnerable to the claim of erasure by
O’Neill
and
Rawson,
as this case involves a claim of negligence, thus encountering Rawson’s conclusion that “mere negligence” did not violate the duty of fair representation in the contract administration context. But the Board’s application of
Rawson
relies exclusively on the type of “one-size-fits-all” theory that
Plumbers & Pipe Fitters
rejected. And, once again,
Rawson
is not a hiring hall case. It concerned the specific question of whether a union violates the duty of fair representation through negligent enforcement of a collective bargaining agreement. Although the Court endorsed what courts had “in general assumed,” namely, that negligence does not “state a claim for breach of the duty of fair representation,”
The Board’s decision here seems in effect to recognize its contradiction of Plumbers & Pipe Fitters. Rather than try to distinguish the case, the Board simply observed that “the circuit court’s assertion that the standard for operation of a hiring hall can and should be different from the standard for contract administration seems to us to be unsupportable.” Board Decision, 329 N.L.R.B. No. 65, slip op. at 3 n.19.
Intervenor’s brief relies on two additional decisions issued after
Plumbers & Pipe Fitters,
one from the Supreme Court,
Marquez v. Screen Actors Guild, Inc.,
The Board’s reliance on its mistaken analysis of
O’Neill
and
Rawson
compels a remand. “An agency action, however permissible as an exercise of discretion, cannot be sustained ‘where it is based not on the agency’s own judgment but on an erroneous view of the law.’”
Sea-Land Service, Inc. v. Department of Transportation,
We now turn to the Board’s second holding — that the union’s conduct did
*618
not, quite apart from any breach of the duty of fair representation, violate §§ 8(b)(1)(A)
&
8(b)(2) of the Act. The latter bars a union from causing an employer to discriminate against an employee in violation of § 8(a)(3), which in turn bars an employer’s discrimination against an employee “to encourage or discourage union membership.” A violation of §
8(b)(2)
would derivatively violate § 8(b)(l)(A)’s ban on union restraint of employees in the exercise of their rights under § 7 of the Act.
Board Decision,
329 N.L.R.B. No. 65, slip op. at 4; see also
id.
at 8 (Member Brame, dissenting);
Radio Officers’ Union of Commercial Telegraphers Union v. NLRB,
The Board in effect has said that its rationale in
Boilermakers
is inapplicable to this context. There we upheld its finding that “[a]ny departure from established exclusive hiring hall procedures which results in a denial of employment to an applicant falls within that class of discrimination which inherently encourages union membership,” and thereby violates §§ 8(b)(1)(A) and (2) of the Act.
While this reasoning makes sense when applied to the volitional actions of union officials, it is unpersuasive when applied to simple mistakes. When as in this case, a union officer in charge of referrals intends to follow the prescribed procedures and thinks he has done so, his inadvertent failure to do so, even to the detriment of an applicant, simply does not carry the message that applicants had better stay in the good graces of the union if they want to ensure fair treatment in referrals.
Board Decision, 329 N.L.R.B. No. 65, slip op. at 4.
Given the focus of § 8(b)(2) on discrimination, we cannot fault the Board’s view that a purely negligent breach of the rules would lack the signaling effect that the provision, and the Board, sought to avoid. But the Board’s analysis is complicated by its additional holding that this approach does not contradict any of its earlier decisions — a statement that, if true, renders inapplicable the Board’s duty to give a “reasoned justification for any departure from its prior policies or practices.”
Pittsburgh Press Co. v. NLRB, 977
F.2d 652, 655 (D.C.Cir.1992) (citing
Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Ins. Co.,
At the time of the Board’s decision, of course, the effect of its holding regarding these “independent” violations of §§ 8(b)(1)(A) & (2) was to ensure that, in the relevant context, the statute imposed no broader liability independent of the duty of fair representation than as construed with that duty. Our reversal on the duty of fair representation theory now puts the question in a different light. If, on remand, the Board again decides to overrule California Erectors, it will need to provide a reasoned justification beyond its current theory of compulsion by the Supreme Court — and any successful justification is likely to support the Board’s more general interpretation of the relevant statutory provisions, assuming that that interpretation does in fact depart from pri- or Board precedent. So our remand on the Board’s first holding makes it, as a practical matter, premature to rule on the sufficiency of its second one.
Similarly, we do not pass judgment on the theory proposed by Member Brane in his dissent, to the effect that if Blevins’s individual negligence did not itself constitute an unfair labor practice, then the union’s subsequent failure to make Jacoby whole did. Board Decision, 329 N.L.R.B. No. 65, slip op. at 7 (Member Brame, dissenting). The Board refused to consider this theory on the grounds that it was raised neither in the General Counsel’s complaint nor during oral argument, see Board Decision, 329 N.L.R.B. No. 65, slip op. at 4 n.27, and Jacoby has not properly appealed this ruling.
For the reasons given we reverse and remand the case to the Board.
So ordered.
