so vague as to deprive him of liberty or property without due process of law, and we turn, therefore, to the merits of that claim.
II.
The Florida Supreme Court first considered the provisions of this legislative oath in State v. Diez, 97 So. 2d 105, a case involving the validity of an indictment for perjury. There the court upheld the constitutionality of the legislation only upon finding it “. . . inherent in the law that when one takes the oath that he has not lent aid, advice, counsel and the like to the Communist Party, he is representing under oath that he has not done so knowingly.” 97 So. 2d, at 110. In the present case the Florida court adhered to this construction of the statute, characterizing what had been said in Diez as a ruling that “the element of scienter was implicit in each of the requirements of the statute.” 125 So. 2d, at 557. We accept without question this view of the statute’s meaning, as of course we must. This authoritative interpretation by the Florida Supreme Court “puts these words in the statute as definitely as if it had been so amended by the legislature.” Winters v. New York, 333 U. S. 507, 514. See Kingsley Pictures Corp. v. Regents, 360 U. S. 684, at 688; Albertson v. Millard, 345 U. S. 242; United States v. Burnison, 339 U. S. 87; Aero Transit Co. v. Commissioners, 332 U. S. 495.
The issue to be decided, then, is whether a State can constitutionally compel those in its service to swear that they have never “knowingly lent their aid, support, advice, counsel, or influence to the Communist Party.” More precisely, can Florida consistently with the Due Process Clause of the Fourteenth Amendment force an employee either to take such an oath, at the risk of subsequent prosecution for perjury, or face immediate dismissal from public service?
