Opinion PER CURIAM.
Appellant union, United Food and Commercial Workers, Local 400, AFL-CIO, seeks relief from an order of the district court dismissing a complaint against the National Labor Relations Board аnd Regional Director Louis J. D’Amico for lack of subject matter jurisdiction. The union sought to challenge a Board ruling in which it refused to set aside a representation election оn the ground that a Board agent had violated the rule it announced in
Excelsior Underwear, Inc.,
I. Background
On February 27, 1981, the union filed a petition with the National Labor Relations Board seeking certification as the collective bargaining representative of a unit of employees of Murry’s Steaks, Inc., a Delaware corporation (the company). The Board’s Regional Director directed that an election be held on May 8, 1981. The сompany submitted a list of the employees eligible to vote in the forthcoming election to the Board. The Board forwarded this list to the union on April 14, 1981. The company later discоvered that one employee had been left off the list and sent that name to the Board on April 15. The Regional Office, however, “neglected” to forward that name to the union.
*278 Because the union thought this last employee was ineligible to vote, it did not seek to contact him or to persuade him to vote for the union in the upcoming election. The uniоn learned of the employee’s eligibility just prior to the election on May 8.
The election was held as scheduled. There were eighteen votes for and eighteen votes аgainst the union, with one vote — the “neglected” employee’s — uncounted because of a union challenge. On May 13 the union withdrew its challenge without waiving any of its rights. On May 15, however, the uniоn filed objections to the election because of the omission of the name from the Excelsior list. On July 2 the Regional Director ordered that the vote be counted. The union then requestеd that the Board review the Director’s decision; the request was denied on August 17. The vote was counted and resulted in a 19-18 loss for the union.
On September 25 the union filed suit in district court seeking an order that the election be set aside and a new election directed. On January 20, 1982, the court dismissed the union’s complaint for lack of subject matter jurisdiction. This appeal followed.
II. Analysis
As a rule, Board representation proceedings are nonadversarial actions and do not result in the issuance of judicially reviewable final orders.
American Federation of Labor v. National Labor Relations Board,
The union attempts to bring its present grievance within the first two exceptions to the nonreviewability rule. It contends that the Board’s failure to live up to its own Excelsior doctrine constitutes the “clear statutory violation” contemplated by Leedom v. Kyne and that the Board’s arbitrary and capricious violation of its own rules and the biased review of the Regional Director’s decision not to set aside the election were “strong and clear” denials of the union’s constitutional right to due process.
The union attempts to combine the
Excelsior
rule with sections 1 and 7 of the Act
2
to demonstrate a clear violation of a statutory scheme. The courts have required, however, that the Board must have disregarded a specific аnd unambiguous statutory directive before its actions will fall within the
Leedom v. Kyne
exception.
See Boire v. Greyhound Corp.,
The union has failed to demonstrate any such statutory violation here. The
Ex
*279
celsior
requirement does not specifically apрear in the National Labor Relations Act. The rule was announced by the Board nearly two decades after enactment of the Act. Essential a tool as the rule may be to fair elections, it cannot reasonably be viewed as a statutory mandate violated by the Board’s actions in this case.
See Physicians National House Staff Association v. Fanning,
In addition, the union contends that the actions of the Rеgional Director and the Board in failing to send to it a complete list of eligible employees or subsequently to set aside the election violated its constitutional rights. We cаnnot agree. The courts have also construed this exception to the general rule of nonreviewability of representation proceedings very narrowly, requiring a “strong and clear” showing that the Board has acted in a manner infringing on the union’s constitutional rights.
McCulloch
v.
Libbey-Owens-Ford Glass Co.,
The union’s allegation that the Board has violated its own rules and regulations by refusing to set aside the еlection in this case does not fit within the narrow confines of the constitutional exception to nonreviewability. In the past, the Board has only required substantial compliance with the
Excelsior
rule. It has overlooked small errors or omissions in the
Excelsior
list and refused to set aside elections on that basis.
See Advance Industrial Security,
In addition, the union alleges that having the Regional Director and the Board review the Director’s alleged transgressions violates its due process right to review untainted by personаl bias. The cases require, however, that the probability of actual bias on the part of the decisionmaker be extremely high and presume the honesty and integrity of agency аdjudicators.
See Withrow v. Larkin,
Thus, we affirm the district court’s dismissal of the union’s complaint for lack of subject matter jurisdiction. We cannot leave the case, howevеr, without voicing our deep concern over the underlying facts set out in this record. There can be no doubt that the vote of the employee whose name was withheld proved to be the determinative vote in the election; we must therefore presume substantial harm to the union because it did not know that he should be included in their campaign efforts. If an еmployer had acted similarly, for whatever reasons, it seems clear from the Board’s past precedent that it would not have treated the union’s allegations in such a summary fashion.
See Advance Industrial Security,
Affirmed.
Notes
. The Board stated:
[W]e now establish a requirement that will be applied in all election cases. That is, within 7 days ... after the Regional Director or the Board has directed an election pursuant to Sections 102.67, 102.69, or 102.85 thereof, the employer must file with the Regional Director an election eligibility list, containing the names and addresses of all the eligible voters. The Regional Director, in turn, shall make this information available to all parties in the case. Failure to comply with this requirement shall be grounds for setting aside the election whenever proper objections are filed.
