has therefore repeatedly been held that an employer has the right to seek local judicial protection from tortious conduct during a labor dispute. See, e. g., Sears, Roebuck & Co. v. Carpenters, 436 U. S. 180 (1978); Farmer v. Carpenters, 430 U. S. 290 (1977); Linn v. Plant Guard Workers, 383 U. S. 53 (1966); Construction Workers v. Laburnum Construction Corp., 347 U. S. 656 (1954).
In Linn v. Plant Guard Workers, supra, at 65, we held that an employer can properly recover damages in a tort action arising out of a labor dispute if it can prove malice and actual injury. See also Farmer v. Carpenters, supra, at 306. If the Board is allowed to enjoin the prosecution of a well-grounded state lawsuit, it necessarily follows that any state plaintiff subject to such an injunction will be totally deprived of a remedy for an actual injury, since the “Board can award no damages, impose no penalty, or give any other relief” to the plaintiff. Linn, supra, at 63. Thus, to the extent the Board asserts the right to declare the filing of a meritorious suit to be a violation of the Act, it runs headlong into the basic rationale of Linn, Farmer, and other cases in which we declined to infer a congressional intent to ignore the substantial state interest “in protecting the health and well-being of its citizens.” Farmer, supra, at 302-303. See also Sears, Roebuck & Co. v. Carpenters, supra, at 196; Linn, supra, at 61.
Of course, in light of the Board’s special competence in applying the general provisions of the Act to the complexities of industrial life, its interpretations of the Act are entitled to deference, even where, as here, its position has not been entirely consistent. NLRB v. J. Weingarten, Inc., 420 U. S. 251, 264-267 (1975); NLRB v. Seven-Up Co., 344 U. S. 344, 347-349 (1953). And here, were only the literal language of §§ 8(a)(1) and 8(a)(4) to be considered, we would be inclined to uphold the Board, because its present construction of the statute is not irrational. Considering the First Amendment right of access to the courts and the state interests identified in cases such as Linn and Farmer, however, we conclude
