OPINION OF THE COURT
I.
This case is before the Court on a petition by Monmouth Medical Center (the Hospital) to review, and a cross-application of the National Labor Relations Board (the Board) to enforce, an order issued by the Board against the Hospital. 1 The order directs the Hospital to bargain collectively with the Hospital Professionals and Allied Employees of New Jersey (the Union). It is predicated on the Board’s decision that the Hospital’s refusal to bargain with the Union constituted an unfair labor practice in violation of section 8(a)(1) and (5) of the National Labor Relations Act. 2
Whether the Hospital’s refusal to bargain was an unfair labor practice depends on whether the Union was properly certified by the Board as the collective bargaining representative of the Hospital’s employees. The Hospital alleged that the representation election which the Union won was flawed by improper pre-election conduct and that certification of the Union following such an election was therefore invalid. The Board rejected the Hospital’s objection at the initial representation proceeding and declined to reconsider it at the unfair labor practice hearing. We conclude that the Board’s certification decision was inconsistent with case law and with previous decisions of the Board itself and amounted to an abuse of discretion. Since the Union was not properly certified as the bargaining representative, the Hospital committed no unfair practice when it refused to bargain. The Hospital’s petition will be granted, the order will be denied enforcement, and the disputed election will be set aside.
II.
On June 16, 1977, the Board conducted a secret ballot election in a unit consisting of the Hospital’s full-time and regular part-time registered nurses and graduate nurses. Of approximately 320 eligible voters, 284 cast valid ballots. The Union won the election by a vote of 148 for the Union to 136 against the Union — an effective difference of six votes. The Hospital filed objections to the election, alleging inter alia, that the election should be set aside because the Union “misused and abused the National Labor Relations Board’s processes to secure a partisan advantage in that it represented to unit employees, directly and indirectly, that the . . . Board endorsed [the Union] in the election”. To support this objection, the Hospital submitted six pieces of literature which had been distributed by the Union during the pre-election campaign.
The first piece of literature, “Exhibit A”, is an official Board-published election pamphlet, entitled “Your Government Conducts an Election”, to which the message “Vote Yes June 16 MMC Auditorium” has been added by hand. At least ten of these altered documents were distributed to voters in May, 1977, by the co-chairperson of the Union’s local steering committee.
*822 The second piece of literature, “Exhibit B”, was mailed to unit employees on or about June 9, 1977. It states, in part:
. On June 13th, there will be a hearing at the National Labor Relations Board regarding the Unfair Labor Practices charged against the Hospital by members of your Steering Committee. The NLRB conducts such hearings only after investigation and rendering merit to such charges. [Emphasis added.] The [Union] has not nor could we be, charged with violating any standard of conduct or representation set to preserve the rights of employees. This hearing proves the Hospital cannot make such a claim. If Mr. Pilla attempted to file such a charge he would realize that he does not stand a chance in a formal hearing as the daily mutilation of the facts would not stand' up as credible evidence at the Labor Board.
Prior to the distribution of Exhibit B, on March 22, 1977, the Union had mailed a letter, “Exhibit C”, which reads in pertinent part:
. If any misguided friend of the administration, probably unaware that they are putting themselves in criminal jeopardy, threaten to take any negative action against you whatsoever for joining or showing interest in a union, that person has violated a federal law. (Emphasis added)
******
WHAT CAN HAPPEN TO THOSE WHO COMMIT AN UNFAIR LABOR PRACTICE?
The law provides that those who commit such violations of the Labor Act can be fined up to $5,000.00 and possibly imprisoned up to one year, or both.
At about the same time that Exhibit B was mailed, the Union mailed another leaflet, “Exhibit D”, which states in part:
Something to think about: The attorneys and agent of the National Labor Relations Board, to whom the hospital and the employees are subject to regarding collective bargaining, ARE UNIONIZED themselves. These people, who are privy to more information than anyone else regarding unions have chosen to unionize years ago. (emphasis in original).
When the experts have chosen this particular method, can it really be the wrong one?
Vote “Yes”
June 16th.
In early and mid-May, the Union mailed two additional leaflets. The first leaflet, “Exhibit E” states in pertinent part:
It is easier for the administrations anti-union campaign, financed with tax deductible hospital funds, to start rumors and spread half-truths than it is for us to send out letters correcting the intentional misinformation many people are being given. WE have nothing to gain by lying to you. When something you hear from the anti-union people contradicts what union organizers have told you, there is any easy way to find out who is telling the truth. Just call the Officer of the Day at the National Labor Relations Board at 645 — 2100. WE have nothing to hide.
The second leaflet, “Exhibit F”, which was mailed within the same time period and context as Exhibit E, but to employees voting in an election unit not at issue here, states in pertinent part:
If you doubt in any way information given you by the administration or by a representative of the union, we urge you to call the National Labor Relations Board at 645-2100 to verify what you’ve been told.
The Regional Director of the NLRB conducted an administrative investigation into the Hospital’s objections. In his Report on Objections, he concluded that Exhibits A and B were not objectionable, but that Exhibits C, D, E, and F were. Accordingly, he recommended that the election be set aside and that a new election be directed. Both the Hospital and the Union filed exceptions to the Regional Director’s report. The Board delegated its authority to hear the exceptions to a three member panel. The *823 panel, in a 2 — 1 decision, overruled the Hospital’s objections, effectively reversing the Regional Director, and certified the Union as the exclusive bargaining representative of the Hospital’s registered and graduate nurses.
The Hospital refused to bargain with the Union, and an unfair labor practice hearing was commenced. 3 The proceeding was conducted by the same panel which had overruled the Hospital’s objections to certification. At the hearing the Hospital defended its refusal to bargain by arguing that the Board had improperly overruled the Hospital’s objections to the election and that, therefore, the Board’s certification of the Union was invalid and could not provide the basis for finding an unlawful refusal to bargain. The panel rejected this argument, again by a 2-1 vote, and granted summary judgment in favor of the NLRB.
Since the Board’s Decision and Order is premised upon its certification of the June 16,1977 election, we must consider the validity of the Board’s certification of the representation election.

We are mindful that the Board has “wide discretion” in establishing the procedure and safeguards for conducting representation elections,
NLRB v. A. J. Tower Co.,
In articulating the “basis for its order”, the Board is free to refer “to other decisions or its general policies laid down in its rules and its annual reports.” [NLRv. Metropolitan Life Ins. Co.,380 U.S. 438 , 443 n.6, [85 S.Ct. 1061 ,13 L.Ed.2d 951 ] (1965)]. However, where the Board has reached different conclusions in prior cases, it is essential that the “reasons for the decisions in and distinctions among these cases” be set forth to dispel any appearance of arbitrariness. 5 [Id. at 442, [95 S.Ct. 1061 ].
Id.

Accord, NLRB v. Saint Francis College,
*824 III.
The gravamen of the Hospital’s complaint is that the literature mailed, distributed, and posted by the Union misrepresented the role of the Board in conducting representation elections and created the impression that the Board favored the Union in the June 16 election. The Hospital’s position is that in thus misleading unit employees the Union compromised the statutory neutrality of the Board.
The Board assumes a supervisory role in representation elections. “It is the Board’s function to provide a laboratory in which an experiment may be conducted, under conditions as nearly ideal as possible to determine the uninhibited desires of the employees.”
General Shoe Corp.,
The Board actively guards its neutral status and will intervene to prevent the improper involvement of the Board and its processes in representation elections. The Board “will not countenance the use of its name in a manner which gives the impression that the Agency has granted a party to an election its imprimatur or support.”
GAF Corp.,
The full Board’s most recent decision in the area of Board neutrality is
GAF Corp.,
As composed, the leaflet at the very least creates an ambiguity in the mind of its reader as to the document’s originator. We have repeatedly held that the Board will not countenance the use of its name in a manner which gives the impression that the Agency has granted a party to an election its imprimatur or support. E. g., J. Ray McDermott & Co., . . .; Rebmar, Inc. . . .; Allied Electrical Products, Inc. . . . As we stated in Rebmar, our concern is not with the substance of the material added to a portion of a Board document, but with the possible impact such propaganda may have on the freedom of choice of the voter. The Board cannot lend its name and prestige to a use which has the tendency to mislead. (emphasis added)
Id., slip op. at 3 — 4.
GAF and the cases cited therein thus establish the test which is to be applied by the Board when deciding whether the Board’s neutrality has been compromised. We turn to a discussion of whether the Board abused its discretion in applying these principles to the facts of the instant case.
IV.
Exhibit A is a sample of an official Board document which has been altered by the addition of a hand-printed partisan message. The Board concluded that the partisan message was readily identifiable as emanating from the Union, and that, in any event, a subsequent mailing of identical unmarked documents cured whatever damage the altered document might have caused. This conclusion does not appear to be consistent with previous decisions of the Board. In
United States Gypsum Company,
In
Allied Electric Products,
The reproduction of a document that purports to be a copy of the Board’s official secret ballot, but which in fact is altered for campaign purposes, necessarily, at the very least, must tend to suggest that the material appearing thereon bears [the Board’s] approval. As there are many legitimate methods available to parties for disseminating campaign propaganda which clearly do not entail an apparent *826 involvement of the Board or its processes, we believe it is unnecessary to permit unlimited freedom to partisans in election cases to reproduce official Board documents for campaign propaganda purposes. (emphasis added).
Id.
at 1272. In
Rebmar, Inc.,
Our concern is not with the substance of the material added to the Board’s official notice of election, but with the possible impact such a partisan message added to an official Board document, or copy thereof, might have on the freedom of choice of the voter.
* * * * * *
To duplicate a part of the Board’s official notice and then to add to it a personal partisan message that may be interpreted by the employee as an endorsement by the Board of one of the parties to the election, and thus have an impact on the employees’ freedom of choice, is, we think, an undesirable use of Board documents designed for another purpose. That the Union’s message in this case may be arguably innocuous and that there may have been at most a narrow or technical violation of the Allied Electric Products rule, is clearly irrelevant. Whether deliberate or unintentional, such action has a tendency to mislead, and we are of the opinion that the Board should guard against having its prestige put to such possible abuse. 11173 NLRB at 1434 . (emphasis added; citation omitted).
In GAF, which did not involve a sample ballot, the Board found that mere ambiguity was enough to make a document objectionable, even though the document was clearly identified as emanating from the union, and contained only some language similar to that used by the Board in its election notices.
Exhibit A is an actual Board document and the union source of the appended partisan message is nowhere admitted. It would seem that, as in Rebmar and GAF, application of the Allied Electric rule is warranted. 12
The Board, in its brief, attempts to distinguish
Silco
and
Ünited States Gypsum
as “merely” being cases in which alteration was found objectionable. In reliance on A.
Brandt & Co., Inc.,
Exhibit B contains a Union reference to an unfair labor practice hearing and the Union’s declaration that the Board had “render[ed] merit” to the charges. We read it in light of Exhibit C, which was sent out prior to the mailing of B and which incorrectly states that criminal penalties attach to those who have been found guilty of unfair practices. The Board excused Exhibit B as being only “inartfully drafted” and not a “substantial” or “patent” mis-characterization of a Board proceeding. Further, to the extent that there was a misleading inference that the Board had already found merit in the unfair practice charges the Board concluded that the harm was mitigated by the references in the letter to “hearings” and “charges”. The Board found Exhibit C permissible because it did not implicate the Board’s documents or proceedings and could not “reasonably have had an impact on the election.”
The exhibits do implicate a Board proceeding — the unfair labor practice hearing. Exhibit B refers directly to such proceedings and Exhibit C misrepresents the penalties which attach to being found guilty in such proceedings. Misrepresentation of the import of being charged in an unfair labor practice hearing was condemned in
Formco, Inc.,
The Board’s second justification, that the exhibits could not reasonably have had an
*828
impact on the outcome of the election, is based in part on an inappropriate test. It is the “tendency” to mislead and the creation of “ambiguity” which
GAF
and
Allied Products
identify as the critical issues to be weighed. Doubts on the question of whether the misconduct actually had an impact should have been resolved against certification. As the court observed in
NLRB v. Trancoa Chemical Corp.,
The Board’s reliance on the reference to “hearings” are “charges” as mitigating the tendency to mislead is misplaced. In
ONA,
Exhibit D appears to strike at the heart of the Board’s neutrality by suggesting that the attorneys and agents of the Board favor unions. It goes so far as to say that the Board favors the “particular method” of unionization upon which the employees were voting. The Board held, however, that an organization could not be presumed to favor unions simply because its employees were represented by a union and that therefore, there could have been no effect on the Board’s neutrality. This completely misses the point. The question is not whether the unionization of its employees proves that the Board actually favors unions. Rather, the question is whether reference by the campaigning Union to unionization of the Board’s employees would create the impression in the minds of the voters that the Board favors unionization.
The Board also concluded that if anything, this exhibit was “campaign propaganda” that employees would recognize and evaluate. We see no reason, and the Board advances none, to conclude that the employ *829 ees would recognize this particular literature as propaganda, or would look behind it and recognize that it misrepresented the Board’s role in conducting elections. 17 This is especially so since the Board’s finding ignores the conclusion of the Regional Director that “[the Union] cloaked itself throughout the election campaign with the appearance of certain expertise as to the purposes and procedures of the National Labor Relations Act and the Board.” We do not see how the Board could hurdle from this finding, and the Director’s finding quoted at paragraph 21 supra, to the conclusion that the misrepresentations were readily identifiable as propaganda.
Exhibits E and F are letters which referred voters to the Board should they have any questions about the Union. The Regional Director found that these items a lone warranted the setting aside of the election. He concluded that the Union had impermis-sibly injected the Board into the campaign, and had suggested that the Board would respond to the employees’ questions in a manner favorable to the Union.
The conclusion that these letters constituted impermissible interference in the election appears to be compelled by
GAF
and by
Formco, Inc.
in which the Board held: “Our concern is with the protection of- our own processes, lest any voter be left with the impression that [the] Board is in favor of any party in an election. We are unwilling to condone any campaign statement
which even implies such bias.”
Y.
For the foregoing reasons the Hospital’s petition for review will be granted and the Board’s cross-application for enforcement will be denied.^ The case will be remanded to the Board so that the disputed election may be set aside.

This Court has jurisdiction of the petitions for enforcement and review under Sections 10(e) and (f) of the Act, Id. §§ 160(e)-(f) (1976).
. Section 8(a)(1) and (5) of the Act provides that: “(a) It shall be an unfair labor practice for an employer — (1) to interfere with, restrain, or coerce employees in the exercise of the rights guaranteed in section 157 of this title; (5) to refuse to bargain collectively with the representatives of his employees, subject to the provisions of section 159(a) of this title.” 29 U.S.C. § 158(a)(1) & (5) (1976).
. A certification decision is not a final order within the meaning of Sections 10(e) and (f) of the Act, and hence is not reviewable by this Court.
AFL v. NLRB,
. A factor here is the closeness of the election. In such cases, closer scrutiny of objections may be required of the Board. We bear in mind the admonition, nowhere adverted to in the Board’s Decision, that where “an election is extremely close, even minor misconduct cannot be summarily excused on the ground that it could not have influenced the election.”

in
Shopping Kart Food Market, Inc.,
. Even under Shopping Kart, which reflects the Board’s most relaxed attitude toward misrepresentation generally, the Board promised that:
. Board intervention will continue to occur in instances where a party has engaged in such deceptive campaign practices as improperly involving the Board and its processes, or the use of forged document's which render the voters unable to recognize the propaganda for what it is.228 NLRB at 1313 (emphasis added).
The Board’s concern with protecting its neutrality was emphasized in
Formco, Inc.,
. GAF was decided by a 3-2 vote of the entire Board. The two dissenters in GAF constituted the majority in our case, it having been decided by a three-member panel. The opinion in the instant case relies on the same cases and the same analysis as did the dissent in GAF. In reference to that dissent, the GAF majority observed that the dissenters were “defin[ing] the words ‘Board document’ too narrowly and construpng] the principles of the cited cases too strictly.” GAF, slip op. at 4. Thus, it appears that the Board has already rejected the analysis upon which the case we are reviewing is based.
. The message was described by the Board as follows:
One side of the handbill was a reproduction of that portion of the election notice entitled, “Rights of Employees” complete with the Board’s seal and name. The only addition to this side of the handbill was a statement superimposed at the top to the effect that “The government protects your right to organize yourself in a union.” The reverse side of the handbill contains an explanation, couched in broad generalized language, of what a union is, how a union functions, and what a collective-bargaining contract contains. Nowhere does the handbill refer to or mention the [Union] by name. (173 NLRB at 1434 ).
. Even where the altered documents have not been official Board publications, the Board has relied on
Rebmar
to invalidate elections if the campaign literature appeared to compromise Board neutrality. In
J. Ray McDermott & Co., Inc.,
. The facts of
Allied Products
are similar to ours. There, the union distributed a document which purported to be a sample copy of the Board’s official ballot, which had been altered to include a printed “X” in the yes box. At the bottom was printed, “Do not mark it any other way — mark ‘Yes’ box only.”
. The Regional Director, although finding that Exhibits C, D, E and F were objectionable, excused Exhibits A and B. He too relied on Brandt. However, Brandt was explicitly distinguished from Rebmar when it was decided. We think that especially after GAF, which was decided after the Regional Director made his findings, and which rejected a dissent grounded partly on Brandt, Rebmar is the more appropriate rule. Further, we recall that in a close election, “even minor misconduct cannot be summarily excused.” See note 4 supra.

Guitón Industries

Division,
. Of course, we do not conclude that the Regional Director’s conclusions should always override the judgment of the Board. Nevertheless, we are unpersuaded by the Board’s rejection of those conclusions in this case, since there has been no reference to any countervailing circumstances or considerations. As the Supreme Court noted in
Universal Camera Corp. v. NLRB,
Evidence supporting a conclusion may be less substantial when an impartial, experienced examiner who has observed the witnesses and lived with the case has drawn conclusions different from the Board’s than when he has reached the same conclusion.

. As to whether there was opportunity to respond, which was suggested for the first time on appeal,
Formco, Inc.,
The impact of the Petitioner’s message upon the freedom of choice of the voter is not amendable to credible or effective response by the Employer. Employees may well view any response by the Employer as an attempt to extricate itself from the damaging effects of an adverse finding by the Board by seeking to mislead them.

. In
NLRB v. Trancoa Chemical Corporation,
In its Brief the Board concludes, “the common sense of the electorate can be trusted to evaluate and fairly discount campaign utterances.” If this means to know instinctively what factual statements are untrue, this is a bit of hyperbole this court will not indulge in. Id. at 460 n. 5.
This sentiment was echoed by the Board itself when it tightened its supervisory control over misrepresentations generally in General Knit, 239 NLRB No. 101 (1978). The Board announced its “conviction that”:
No matter what the ultimate sophistication of a particular electorate, there are certain circumstances where a particular misrepresentation or misrepresentations may materially affect an election. In such circumstances, that election should be set aside in order to maintain the integrity of Board elections.
Id.
. In pertinent part, the dissent concludes:
Contrary to the position taken by the majority, it is obvious that the Union through the disputed language was stating, in an unambiguous manner, that the Board “through its unionized attorneys and agents” is pro-union and that what the Union tells the employees “must be true because the Board will verify” its statements. That the Board will not do so is hardly relevant, for it is the likely impact on employees of the [Union’s] misleading campaign propaganda involving this Board that is of concern here. The impact remains unaffected by the truth unless the unrealistic assumption is made that a substantial number of employees will call the Board and learn the truth — i.e., that the Board will not get involved in partisan matters. But even if the employees did not look behind su.ch campaign propaganda, that would not justify or render innocuous the [Union’s] gratuitous and improper attempt to make the employees believe this Board is not impartial.
