of a labor union. The Yinson opinion in Douds upheld § 9 (h) on the basis that it was “intended to prevent future action rather than to punish past action.” 339 U. S., at 414. In Brown, it was likewise argued that the statute there involved was “preventive rather than retributive in purpose.” 381 U. S., at 457. That view was rejected. The question, we said, was whether § 504 inflicted “punishment” which, we pointed out, “serves several purposes: retributive, rehabilitative, deterrent— and preventive.” Id., at 458. The dissenters — Mr. Justice Clark, Me. Justice Harlan, Me. Justice Stewart, and Mr. Justice White — concluded that Douds was “obviously overruled.” Id., at 46A-465. Whatever may be said technically about any remaining vitality of the Douds case, it obviously belongs to a discredited regime, though, like Plessy v. Ferguson, 163 U. S. 537, it has never been officially overruled.
The rule invoked by the Court to deny petitioner the opportunity to challenge that bill of attainder in this proceeding is, as stated by Mr. Justice Black in his separate opinion in Dennis v. United States, 384 U. S. 855, 878, “a new court-made doctrine.” As he pointed out in that opinion, the prior decisions of this Court relied on to deny the defense of unconstitutionality of a federal law were instances of false claims for benefits to which the complainant had “no possible right whether the statute was constitutional or unconstitutional.” Ibid.
In this case, however, Congress installed an unconstitutional barrier to receipt of the benefits administered by the Labor Board. Since § 9 (h), in light of Brown, was plainly unconstitutional, petitioner’s union was entitled to those services without the filing of any affidavit. Therefore, unlike prior cases, the United States had been deprived of nothing and defrauded of nothing by the filing of any affidavit or other form of claim.
I would reverse the judgment below.
