March 1969 to twenty years in federal prison, but seven years later, in April 1976, was released on parole. While at liberty he not only committed another armed bank robbery but was also convicted of shoplifting. So in July 1977 his parole was revoked, and he returned to prison. He now appeals the district court’s summary dismissal of a habeas corpus petition he brought in forma pauperis. The district court invoked 28 U.S.C. § 1915(d), which authorizes such a disposition whenever the court is “satisfied that the action is frivolous or malicious.”
In his petition to the district court Warren raised three issues. Two are without substance; they were properly dismissed by the district court. One of these two claims — that certain parole hearings were held “out-of-time” — Warren has not pursued on appeal. The other — that Warren was denied due process when he was not permitted a fellow inmate’s assistance throughout one of his parole hearings — runs afoul of a recent Supreme Court case establishing that an inmate does not have a right to assistance at a parole release hearing.1 To escape the force of that authority Warren has attempted to argue that the parole hearing in question, although it was held more than a year after the revocation of his parole, somehow constituted a revocation hearing rather than a release hearing. We find no merit in this contention, and pursue it no further here.
Warren’s remaining claim is his ex post facto claim, which is hardly “frivolous.” It is based on the fact that when Warren was first convicted of bank robbery in 1969 the United States Board of Parole was still exercising its discretion without reference to any explicit standards other than its statutory mandate;2 not until 1973 did the Board begin using a set of guidelines distilled from its prior practice.3 But those guidelines, adopted four years after Warren was first convicted, are now being used to determine his eligibility for rerelease after the revocation of his parole. Warren claims that the application to his case of guidelines promulgated after his first conviction violates the federal ex post facto clause of the Constitution.4
Warren’s appeal raises this question regarding the reach of the ex post facto prohibition for the first time in this Circuit. The Second,5 Sixth,6 Seventh,7 and Ninth Circuits8 have rejected similar claims, but in a somewhat analogous ease the Third

The Supreme Court has twice deferred consideration “whether the new guidelines are consistent with the Parole Commission and Reorganization Act of 1976, 90 Stat. 219,” and “whether their enforcement may violate the Ex Post Facto Clause of the Constitution.” United States v. Addonizio, 442 U.S. 178, 184, 99 S.Ct. 2235, 2239-2240, 60 L.Ed.2d 805 (1979); United States Parole Commission v. Geraghty, 445 U.S. 388, 390 n.1, 408, 100 S.Ct. 1202, 1205, 63 L.Ed.2d 479 (1980). Most recently, the Court vacated and remanded for further consideration in light of Weaver v. Graham, 450 U.S. 24, 101 S.Ct. 960, 67 L.Ed.2d 17 (1981), a Ninth Circuit decision rejecting an ex post facto challenge to retroactive application of the parole guidelines. Portley v. Grossman, 450 U.S. 962, 101 S.Ct. 1476, 67 L.Ed.2d 611 (1981). The prisoner in Portiey was sentenced in 1972 and released on parole in 1974. The Parole Commission revoked his parole on the basis of two state convictions for offenses committed while on parole and applied the new parole guidelines to establish a date for reparole. See Portley v. Grossman, 444 U.S. 1311, 100 S.Ct. 714, 62 L.Ed.2d 723 (Rehnquist, Circuit Justice, 1980) (denying application for stay).

The majority, drawing support from Gryger v. Burke, 334 U.S. 728, 68 S.Ct. 1256, 92 L.Ed.2d 1683 (1948), suggests that in Warren’s case “the guidelines — if they punish at all— punish acts committed after they were promulgated.” at 194. The Supreme Court in Gryger carefully noted that the recidivist statute there at issue escaped condemnation under the ex post facto clause because “[t]he sentence as a fourth offender or habitual criminal [was] not to be viewed as either a new jeopardy or additional penalty for the earlier crimes.” Rather, it was “a stiffened penalty for the latest crime, which [was] considered to be an aggravated offense because a repetitive one.” 334 U.S. at 732, 68 S.Ct. at 1258. But the Parole Commission, unlike the tribunal that sentenced Gryger as a fourth offender, is not a court of law. It lacks power to try and convict for any offense, state or federal. Its sole authority is to adjust the prison time Warren serves for his 1969 conviction. See 18 U.S.C. § 4210(b)(2) (1976). Thus any additional days in prison the parole guidelines may require would enhance punishment for Warren’s 1969 federal conviction; those days cannot count as punishment for crimes left to state or federal courts to try and, upon conviction, to sanction. See also Green *198field v. Scafati, 277 F.Supp. 644 (D.Mass.1967) (three-judge court), aff’d mem., 390 U.S. 713, 88 S.Ct. 1409, 20 L.Ed.2d 250 (1968).

A legislature may not augment a crime' retroactively by reason of the ex post facto clause. The judiciary may not do so through statutory construction by reason of the due process clause. Bouie v. City of Columbia, 378 U.S. 347, 353-54, 84 S.Ct. 1697, 1702-1703, 12 L.Ed.2d 894 (1964); Marks v. United States, 430 U.S. 188, 191-92, 97 S.Ct. 990, 992-993, 51 L.Ed.2d 260 (1977). The majority does not suggest that the acts of administrative or executive boards are immune from the same constraint.

As the majority observes, the claim Warren emphasized on appeal is “hardly ‘frivolous,’ ” at 185, thus the district court acted improperly in invoking § 1915(d) to dismiss Warren’s action. As the length of the majority opinion indicates, the district court casts a heavy burden on this court when it dismisses, without pausing to offer reasons, a case that cannot fairly be characterized as “frivolous or malicious.” See also Fed.R.App.P. 24(a) (requiring a written statement of reasons when leave to appeal in forma pauperis is denied by the district court).

Ruip v. United States, 555 F.2d 1331 (6th Cir. 1977); Zeidman v. United States Parole Commission, 593 F.2d 806 (7th Cir. 1979); Rifai v. United States Parole Commission, 586 F.2d 695 (9th Cir. 1978). But cf. Geraghty v. United States Parole Commission, 579 F.2d 238 (3d Cir. 1978), vacated and remanded on other grounds, 445 U.S. 388, 100 S.Ct. 1202, 63 L.Ed.2d 479 (1980); United States ex rel. Graham v. United States Parole Commission, 629 F.2d 1040 (5th Cir. 1980); Hayward v. U.S. Parole Commission, 502 F.Supp. 1007 (D.Minn.1980) (holding, after evidentiary hearing before magistrate, that post-sentencing change in parole guidelines violates ex post facto clause), appeal docketed, 659 F.2d 857 (8th Cir. 1981).

In Zeidman v. United States Parole Commission, 593 F.2d 806 (7th Cir. 1979), the district court granted summary judgment for the Government. The record, however, contained at least the Parole Commission’s Hearing Summary, which showed that the prisoner had received individualized consideration. See id. at 808. In addition, the record must have contained the Government’s responses to the complaint, including a request for summary adjudication. In both Ruip v. United States, 555 F.2d 1331 (6th Cir. 1977), and Rifai v. United States Parole Commission, 586 F.2d 695 (9th Cir. 1978), the courts of appeals neglected to explain the posture of the case below when the district court rejected the prisoner’s claims. The district court dockets in both cases, however, reveal that the Government had at least filed a response to the prisoner’s petition. See Ruip v. United States, No. 75-1167 (N.D.Ohio Feb. 18, 1976); Rifai v. United States Parole Commission, Civ. No. 77-194T (W.D.Wash. Mar. 16, 1978). But see Richards v. Crawford, 437 F.Supp. 453 (D.Conn.1977) (rejecting ex post facto challenge to post-1976 changes in parole guidelines and dismissing petition for habeas corpus without requiring service).

The margin statement made by the court (see maj. op. footnote 57) that Warren, a pro se complainant, “did not and cannot allege a judicially remediable claim,” jars with the approach of most other federal courts (see note 6 and accompanying text supra) treating similarly composed allegations of other pro se petitioners as at least worthy of a response. I therefore cannot agree, in light of the contrary indications by other federal courts, that this court can say “with assurance that under the allegations of the pro se [petition], which [must be held] to less stringent standards than formal pleadings drafted by lawyers, it appears ‘beyond doubt that the [petitioner] can prove no set of facts in support of his claim which would entitle him to relief.’ ” Haines v. Kerner, 404 U.S. 519, 520-21, 92 S.Ct. 594, 595-596, 30 L.Ed.2d 652 (1972), quoting Conley v. Gibson, 355 U.S. 41, 45—46, 78 S.Ct. 99, 101-102, 2 L.Ed.2d 80 (1957).
