Appellant appeals from an order of the District Court for the District of Arizona, entered July 17, 1968, denying his motion to vacate sentence. On April 2, 1962, appellant was committed to the custody of the Attorney General for a term of ten years, on his plea of guilty to a violation of 18 U.S.C. § 1201 (a) [Federal Kidnaping Act], which, in relevant part, provides:

Appellant was released on parole from the Federal Penitentiary in June 1968, and is presently incarcerated in the Arizona State Penitentiary, serving a term of four to five years, following his conviction of assault with a deadly weapon. A detainer and parole violator warrant was filed against appellant by the Board of Parole, and appellant now faces the possibility of the revocation of his parole when his Arizona sentence expires in February, 1971.

At arraignment in the District Court, on March 26, 1962, appellant, represented by counsel, waived indictment by grand jury and elected to proceed on an information filed by the United States Attorney. The charging part of the information filed, reads as follows:

At the time of his arraignment, Rule 7, Federal Rules of Criminal Procedure, in parts pertinent, provided, and now provides, as follows:

In Smith v. United States, 360 U.S. 1, at p. 10 , 79 S.Ct. 991, at 997 , 3 L.Ed.2d 1041 (1959), the Supreme Court of the United States held that since a violation of the Federal Kidnaping Act may be punished by death if the victim is not liberated unharmed, and if the jury so recommends, a prosecution for that offense by information instead of indictment violated Rule 7(a), and that the accused’s conviction was invalid even though he waived indictment and it was not alleged or proved that the victim was harmed. In closing its opinion, the Court stated:

In United States v. Jackson, 390 U.S. 570 , 88 S.Ct. 1209 , 20 L.Ed.2d 138 (1968), the Supreme Court eliminated the death penalty provision of the Act as tending to deny the accused his Fifth Amendment right not to plead guilty, and the Sixth Amendment right to trial by jury, but upheld the validity of the Act after removal of the death penalty provision.

Following the announcement of the decision in United States v. Jackson, swpra, appellant filed his motion in the District Court to vacate the sentence imposed upon him following his guilty plea. The District Court denied appellant’s motion to vacate his sentence, and by written opinion reported at 287 F.Supp. 96 (D. Ariz.1968), stated, inter alia, at pp. 97-98:

We are unable to agree with the conclusions reached by the District Court.

The Government asserts, in effect, that the situation must be viewed as it existed in 1968 following the rendition of Jackson by the Supreme Court and at the time of the hearing of appellant’s motion to vacate sentence, at which time the death penalty clause of the Federal Kid-naping Act had been declared unconstitutional. We reject such contention. In our view we must take the situation as it existed in March 1962, when appellant entered his plea of guilty, at which time the death penalty clause was a part of the Act and its validity had not been questioned.

To reason, as did the District Court, that, under the doctrine of retroactivity, the death penalty clause of the Act had been unconstitutional since the time of its enactment in 1934, overlooks the realities that faced appellant in 1962 when called upon to plead to the charge under the Act which embraced the death penalty clause. To say that the appellant, at the time of his arraignment, should have anticipated that at some future time such clause would be held by the Supreme Court of the United States to be unconstitutional, has no persuasive force in the proper context of this case.

In 1962 the appellant was in the same situation as were the defendants in Jackson when they were charged with a violation of the same Act charged against the appellant. In that case, the District Court dismissed the count of the indictment charging a violation of the Federal Kidnaping Act by stating:

On appeal to the Supreme Court from the judgment of dismissal, the Supreme Court in Jackson stated, 390 U.S. at pp. 581-583, 88 S.Ct. at p. 1216 :

“The Government suggests that, because the Act thus operates ‘to mitigate the severity of punishment,’ it is irrelevant that it ‘may have the incidental effect of inducing defendants not to contest in full measure.’ We cannot agree. Whatever might be said of Congress’ objectives, they cannot be pursued by means that needlessly chill the exercise of basic constitutional rights. Cf. United States v. Robel, 389 U.S. 258 , 88 S.Ct. 419 , 19 L.Ed.2d 508 ; Shelton v. Tucker, 364 U.S. 479, 488-489 , 81 S.Ct. 247, 252 , 5 L.Ed.2d 231 . The question is not whether the chilling effect is ‘incidental’ rather than intentional; the question is whether that effect is unnecessary and therefore excessive. In this case the answer to that question is clear. * * Whatever the power of Congress to impose a death penalty for violation of the Federal Kidnaping Act, Congress cannot impose such a penalty in a manner that needlessly penalizes the assertion of a constitutional right. See Griffin v. State of California, 380 U.S. 609 , 85 S.Ct. 1229 , 14 L.Ed.2d 106 .”

[Footnotes omitted. Italics ours.]

The same considerations which moved the Supreme Court in Jackson to hold the death penalty clause of the Federal Kidnaping Act to be unconstitutional, were present in 1962 when appellant entered his plea of guilty. The presence of the death penalty clause in the Act must be accorded the same chilling effect on appellant’s exercise of his constitutional right under the Fifth Amendment to plead “not guilty”, and his constitutional right under the Sixth Amendment, to a jury trial, as was the chilling effect on the defendants in Jackson to exercise the same constitutional rights.

Since the order of the District Court must be reversed on constitutional grounds, we deem it unnecessary to discuss the efficacy of appellant’s prosecution by information rather than by indictment.

The order of the District Court is reversed.
