delivered the opinion of the Court.
Thе National Labor Relations Board refused to include, in a cease-and-desist order against Heck’s Inc., a provision sought by respondent union, as charging party, that Heck’s reimburse respondent’s litigation ex
*3
penses and excess organizational costs incurred as a result of Heck’s unlawful conduct. The Board’s stated reason was that “it would not on balance effectuate the policies of the [National Labor Relations] Act to require reimbursement with respect to such costs in the circumstances here.”
Heck’s Inc.,
191 N. L. R. B. 886, 889 (1971). Respondent prevailed, however, in enforcement and review proceedings in the Court of Aрpeals for the District of Columbia Circuit. That court enlarged the Board’s order by adding provisions, paragraphs 2 (e) and (f), that Heck’s “[p]ay to the Union any extraordinary organizational costs which the Union incurred by reason of Heck’s policy of resisting organizational efforts and refusing to bargain, such costs to bе determined at the compliance stage of these proceedings,” and “[p]ay to the Board and the Union the costs and expenses incurred by them in the investigation, preparation, presentation, and conduct of these cases before the National Labor Relations Board and the cоurts, such costs to be determined at the compliance stage of these proceedings.” 155 U. S. App. D. C. 101,
Heck’s Inc. operates a chain of discount stores in the Southeast section of the country. Its resistance to union organization has resulted in some 11 proceedings beforе the National Labor Relations Board. 1 This case grew out of its efforts to prevent organization by respondent *4 union of Heck’s employees at its store in Clarksburg, West Virginia. The case was twice before the Board. In its first decision, the Board determined that Heck’s violated § 8 (a) (1) of the Act, 29 U. S. C. § 158 (a) (1), by threatening and coercively interrogating employees during respondent’s organizational campaign, and by conducting a nonsecret poll to ascertain employee support for the union. Further, the Board found that Heck’s “flagrant repetition” of similar unfair labor practices at its other stores and its “extensive viоlations of the Act” in the Clarksburg store justified an inference that Heck’s did not entertain any good-faith doubt concerning majority support for respondent union when the company refused to recognize and bargain with the union on the basis of authorization cards signed by a majority of employees. Accordingly, the Board found that Heck’s violated §§ 8 (a)(5) and (1) of the Act, 29 U. S. C. §§ 158 (a)(5) and (1). Finally, because Heck’s extensive violations were found to have made a free and fair election impossible, an order directing Heck’s to bargain with the union was entered. The Board rejected, however, the union’s argument that adequate reliеf required certain additional remedies, including reimbursement of litigation expenses and excess organizational costs incurred as a result of Heck’s unlawful behavior. 2 Heck’s Inc., 172 N. L. R. B. 2231 n. 2 (1968).
The Court of Appeals for the District of Columbia Circuit enforced the Board’s order, but remanded to the
*5
Board for further consideration of additional remedies including reimbursement of litigation expenses and excess organizational costs. 139 U. S. App. D. C. 383,
Prior to review of its supplementary decision by the Court of Appeals, the Board issued its decision in Tiidee Products, Inc., 194 N. L. R. B. 1234 (1972), in which the Board ordered reimbursement of litigation expenses in the context of a finding that an еmployer had engaged in “frivolous litigations.” 7 The Board’s opinion in Tiidee reasoned that industrial peace could be best achieved if “speedy access to uncrowded Board and court dockets [were] available” and therefore that an assessment of legal fees would serve the public interest by “discouraging] future frivolous litigation,” id., at 1236. The Board did not explain why those considerations had not *7 led it to order similar relief in this case. The Court of Appeals therefore concluded in the present case that the Board had abandoned its policy against award of litigation expenses and excess organizational costs, 8 stating:
“Althоugh the Board in its Supplemental Decision in this case has nowhere characterized the litigation as frivolous, it has used the language of ‘clearly aggravated and pervasive’ misconduct; and in its original opinion it questioned Heck’s good faith because of its ‘flagrant repetition of conduct previously found unlawful’ at other Heck’s stores. It would appear that the Board has now recognized that employers who follow a pattern of resisting union organization, and who to that end unduly burden the processes of the Board and the courts, should be obliged, at the very least, to respond in terms of making good the legal еxpenses to which they have put the charging parties and the Board. We hold that the case before us is an appropriate one for according such relief.” 155 U. S. App. D. C., at 106,476 F. 2d, at 551 .
*8 The Court of Appeals also viewed Tiidee as the signal of a shift in the Board’s attitude toward excess organizational costs. In Tiidee, the Board refused to order reimbursement of excess organizational costs because “ ‘no nexus between [the employer’s] unlawful conduct’ ” had been proved. Ibid. Since, in the instant case, the Board had indicated that Heck’s violations had probably caused respondent to incur excess organizational costs, a nexus' was proved and aсcordingly the court held that respondent was entitled to an order directing reimbursement of organizational costs.
In the circumstances of this case, the Court of Appeals, in our view, improperly exercised its authority under §§10 (e) and (f) to modify Board orders, and the case must therefore be returned to the Board.

Congress has invested the Board, not the courts, with broad discretion to order a violator “to take such affirmative action ... as will effectuate the policies of [the Act].” 29 U. S. C. § 160 (c); see,
e. g., Golden State Bottling Co.
v.
NLRB,
There are, however, facial inconsistencies between the Board’s opinion in this case and the
Tiidee
decision, and the Court of Appeals therefore correctly declined to resolve those inconsistencies by substituting Board counsel’s rationale for that of the Board. 155 U. S. App. D. C., at 107 n. 8,
It is a guiding principle of administrative law, long recognized by this Court, that “an administrative determination in which is imbedded a legal question open to judicial review does not impliedly foreclose the administrative agency, after its error has been corrected, from enforcing the legislative policy committed tо its charge.”
FCC
v.
Pottsville Broadcasting Co.,
*11 The judgment of the Court of Appeals is reversed insofar as paragraphs 2 (e) and (f) were added to the Board’s order, and the case is remanded to the Court of Appeals with direction that it be remanded to the Board for further proceedings.
It is so ordered.
Notes
The many proceedings are cited in the opinion of the Court of Appeals, 155 U. S. App. D. C. 101, 102 n. 1,
The Board also rejected respondent’s requests for provisions directing the mailing of notices to employees; either a cоmpany-wide bargaining order or a shifting of the burden of proof in future cases to require Heck’s to demonstrate its good faith in rejecting authorization cards; injunctions under § 10 (j) of the Act, 29 U. S. C. §160(j); increased access to employees; and a “make-whole” provision directing compensation to employees for collective-bargaining benefits lost as a result of the employer’s unlawful conduct.
The remand was ordered in light of the Court of Appeals’ intervening decision in
International Union of Elec., Radio & Mach. Workers
v.
NLRB,
138 U. S. App. D. C. 249,
The Board directed Heck’s to mail notices of the Board’s amended order to the homes of all employees at each of Heck’s store locations; to provide the union with reasonable access for a one-year period to bulletin boards and other places where union notices are normally posted; and to provide the union with a list of names and addresses of all employees at all locations, to be kept current for one year.
The Board also refused to order, as sought by respondent, that notices of the Board’s decision be read to assembled groups of employees; that a company wide bargaining order be issued; that the company be required to bargain whenever the union obtained an authorization card majority at other locations; that greater access to employees on company property be granted; and that a “make-whole” provision for reimbursement of dues and fees, and collective-bargaining benefits, lost as a result оf the unlawful refusal to bargain, be ordered.
In support of this proposition, the Board relied upon
Republic Steel Corp.
v.
NLRB,
The Board’s decision in
Tiidee
was issued after supplementary proceedings following a remand from the Court of Appeals. See n. 3,
supra.
In an opinion filed April 25, 1974, the Court of Appeals, on review of the Board’s supplementary decision in
Tiidee,
enforced as modified the Board’s" amended order.
International Union of Elec., Radio & Mach. Workers
v.
NLRB,
163 U. S. App. D. C. 347,
The Court of Appeals made clear that the enlargеment of the Board order was based squarely on the Board’s change of policy perceived to have been made by Tiidee. The court refused to decide the question argued by respondent union that, independently of Tiidee, an order of reimbursement should be directed. The Court of Appeals said:
“There are, it seems to us, obvious difficulties [in relying upon the subsidiary role of the charging party as a basis for denial of litigation expenses], certainly in the case of an employer who appears to look upon litigation as a convenient means of delaying — and thereby perhaps avoiding — the fatal day of union recognition and collective bargaining. We need not pursue those difficulties in detail, however, for the reason that the Board itself has subsequently departed from the rationale upon which its refusal of litigation expenses in this case is based.” 155 U. S. App. D. C., at 105,476 F. 2d, at 550 (emphasis added).
We thus have no occasion at this time to address the question whether the Board’s broad powers undеr § 10 (c), 29 U. S. C. § 160 (c), to fashion remedies include power to order reimbursement of litigation expenses and excess organizational costs.
Appellate courts ordinarily apply the law in effect at the time of the appellate decision, see

In its present posture the case does not, of cоurse, present the question whether Board failure, on remand, to clarify the apparent inconsistency in its decisions would warrant reversal on review. Compare
