concurs in the reversal of the judgment. Since, however, counsel requested that all *260government employees be excluded from the jury in these cases, he thinks the request should have been granted for the reasons stated by the dissenting Justices in Frazier v. United States, 335 U. S. 497, and in Dennis v. United States, ante, p. 162.

In this case the trial court did not permit counsel for petitioner to interrogate prospective government employee jurors upon voir dire examination with specific reference to the possible influence of the “Loyalty Order,” Executive Order No. 9835, on their ability to render a just and impartial verdict. Such questioning was permitted in Dennis v. United States, ante, p. 162; see n. 4 of the Court’s opinion, ante, pp. 170-171.

We said in Dennis that “Preservation of the opportunity to prove actual bias is a guarantee of a defendant’s right to an impartial jury.” Ante, pp. 171-172. Since that opportunity was denied in this case, the petition for writ of certiorari is granted and the judgment of the Court of Appeals is reversed.

Reversed.
