Defendant was indicted on four counts of narcotics violations — two counts charging violations of 26 U.S.C. § 4705 (a) and two charging violations of 21 U.S.C. § 174. ^[1] By statute, persons convicted and sentenced for these violations are not eligible for parole. 26 U.S.C. § 7237(d). On February 12, 1968, the defendant appeared for arraignment without counsel and the district court ordered pleas of not guilty entered in his behalf. Also, at defendant’s request, an attorney of his own choice was appointed to represent him. On April 29, 1968, the defendant accompanied by his court appointed attorney, appeared before the district court and requested leave to plead guilty to all four counts. The court made diligent inquiry as to defendant’s understanding of the nature of the charges against him and as to the voluntariness of the plea. Also, defendant was advised as to the minimum and maximum sentences that could be imposed. ^[2] But no mention was made by the court or anyone else as to the defendant’s ineligibility for parole on any sentence imposed. On the basis of this inquiry the defendant’s pleas of guilty were accepted and thereafter the court sentenced him to concurrent five year terms on each count. Some four months later the defendant, acting pro se, filed the instant § 2255 motion to vacate sentence and alternatively[*691] a motion to withdraw his guilty pleas under Fed.R.Crim.P. 32(d). He complains, among other things, that when he pleaded guilty he did not know that he would be ineligible for parole on any sentence imposed; that in fact he was advised by his attorney that parole would be available to him and that had he known that it was not he would not have pleaded guilty. These motions were denied without a-hearing, ^[3] as were defendant’s motions for rehearing.

Fed.R.Crim.P. 11, as amended effective July 1, 1966, provides in pertinent part:

“The court may refuse to accept a plea of guilty, and shall not accept such plea * * * without first addressing the defendant personally and determining that the plea is made voluntarily with understanding of the nature of the charge and the consequences of the plea.” (Italics ours).

The narrow issue presented by this appeal is whether ineligibility for parole is a consequence of defendant’s guilty plea about which the district court must address the defendant personally before accepting the plea. ^[4] Rule 11 lays down no specific tests or standards by which the consequences of a plea of guilty may be ascertained or determined and there is a difference of opinion among the circuits on the resolution of this issue. Compare Munich v. United States, 337 F.2d 356 (9th Cir. 1964) with Trujillo v. United States, 377 F.2d 266 (5th Cir.), cert. denied, 389 U.S. 899, 88 S.Ct. 224, 19 L.Ed.2d 221 (1967) and Smith v. United States, 116 U.S.App.D.C. 404, 324 F.2d 436, cert. denied, 376 U.S. 957, 84 S.Ct. 978, 11 L.Ed.2d 975 (1963). Relying principally on Trujillo and Smith the government takes the position that parole is merely a matter of legislative grace which may be administratively granted or withheld and therefore not within the ambit of Rule 11. The short answer to this is that it fails to distinguish between availability and eligibility for parole. It may be “legislative grace” for Congress to provide for parole but when it expressly removes all hope of parole upon conviction and sentence for certain of-fences, in our opinion this is in the nature of an additional penalty.

Next, the government advances the argument made in Smith that the defendant pleaded guilty knowing that he could be sentenced to a maximum of eighty years on the four counts of the indictment; that the effect of parole, even if available on this maximum sentence, would have been far in excess of the five year sentence actually imposed. Inexplicably the government fails to develop this argument. If its intention is to show lack of prejudice we reject it. Under Rule 11 the defendant is entitled to know the consequences of his plea before entering it. ^[5] This mandate is not nor can it be satisfied by hindsight reasoning comparing the actual sentence[*692] with what it could have been. ^[6] The language of the rule is clearly designed to enable a defendant to assess the risk that he is taking by entering a plea of guilty. ^[7]

Nor can we accept the argument made in Trujillo that ineligibility for parole is a contingency too remote to be a significant consequence of a plea of guilty. In that case the court attempted to illustrate this point by observing that such matters as loss of passport, deportation, loss of voting privileges and undesirable discharge from the armed services, all of which may result from a plea of guilty, have been determined not to be “consequences of the plea” within the scope of Rule 11. We merely comment that these are collateral consequences, civil in nature, while parole goes directly to the length of time a defendant is to be incarcerated. ^[8]

In Munich, supra 337 F.2d at 361, the court stated: “In our opinion one who, at the time of entering a plea of guilty, is not aware of the fact that he will not be eligible for probation or parole, does not plead with understanding of the consequences of such a plea.” We think this is the better view. The nature of parole is well understood, and its availability may be regarded as assumed by the average defendant. Just as the “depressive effect” of a detainer casts a legally cognizable shadow, Smith v. Hooey, 393 U.S. 374, 379, 89 S.Ct. 575, 21 L.Ed.2d 607 (1969), the removal of hope due to the loss of all opportunity to earn “good time” is a substantial deprivation, effecting a fundamental variation in sentence beyond mere calendar years. We do not suggest that a defendant need be given a detail of every consequence of his sentence, but the loss of something important enough to make a deprivation after sentence constitutionally impermissible, cf. Greenfield v. Scafati, 277 F.Supp. 644 (D.Mass.1967), aff’d, 390 U.S. 713, 88 S.Ct. 1409, 20 L.Ed.2d 250 (1968), is a matter of which a defendant should be informed in advance.

Here the defendant would be required to serve five years when he expected that with parole he might be free after serving some twenty months. This increase in imprisonment is far from inconsequential. Where a defendant pleads on the false expectation that he will be eligible for parole, in our. opinion the policy of Rule 11 is not effectuated. Smith v. United States, 400 F.2d 860 (6th Cir. 1968).

The government in its brief seeks to make much of the fact that this defendant was represented by competent counsel when he changed his plea. The presence of counsel, however, does not relieve the court of its responsibility of inquiry under Fed.R.Crim.P. 11. Fultz v.[*693] United States, 365 F.2d 404, 408 (6th Cir. 1966); United States v. Diggs, 304 F.2d 929, 930 (6th Cir. 1962) (eases cited) ; United States v. Lester, 247 F.2d 496, 500 (2d Cir. 1957).

We hold that ineligibility for parole is a consequence of a plea of guilty and under Rule 11 the district court should not have accepted the guilty plea without first informing the defendant that conviction upon the plea would make him ineligible for parole.

This brings us to the question of the relief to which this defendant is entitled. Had the sentencing occurred after April 2, 1969, he would have been entitled to plead anew. McCarthy v. United States, 394 U.S. 459, 89 S.Ct. 1166, 22 L.Ed.2d 418 (April 2, 1969). That decision, however, is not retrospective. Halliday v. United States, 394 U.S. 831, 89 S.Ct. 1498, 23 L.Ed.2d 16 (May 5, 1969). Accordingly, the procedure followed as to Halliday, Halliday v. United States, 380 F.2d 270 (1st Cir. 1967) viz., a hearing before another judge to determine whether his plea was in fact voluntarily made even though the court had not informed him as to the unavailability of parole, should be adopted. The burden as to voluntariness is, of course, upon the government.

Reversed and remanded to the district court for proceedings consistent with this opinion.
