indicates that an appeal such as is here involved was within the contemplation of Congress:
On occasion a Federal court requires the suppression of evidence in connection with a probation revocation hearing, a hearing on a motion for a new trial based on newly discovered evidence, a sentencing proceeding, or other criminal proceeding. While there are sound reasons for believing that any judge making such an order may be acting ultra vires in terms of the purposes of such a hearing, and thus may be subject to a petition for a writ of mandamus to correct his action, S. 3132 is designed to obviate any such problems by affording the Government a certain and efficient remedy through the right to appeal.
S.Rep.No.91-1296, 91st Cong., 2d Sess., at 12 (1970) (footnotes omitted) (emphasis added). The report continues:
The amended Criminal Appeal Act is intended to be liberally construed so as to effectuate its purpose of permitting the Government to appeal from dismissals of criminal prosecutions by district courts in all cases where the Constitution permits, and from all suppressions and exclusions of evidence in criminal proceedings, except those ordered during trial of an indictment or information. S. 3132 places on the face of section 3731 an explicit expression of this intent, in view of the restrictive judicial interpretations of congressional intent which have resulted from the histories of the earlier versions of section 3731 despite strong indications in the debate on the 1907 act that it should be broadly interpreted.
Id. at 18 (footnotes omitted).
Accordingly, we hold that the order is appealable.
III. THE MERITS
As the court below correctly stated, the Federal Rules of Evidence, except those relating to privileges, do not apply to sentencing proceedings. Fed.R.Evid. 1101(d)(3). The statute, 18 U.S.C. § 3577, moreover, requires that “[n]o limitation” be placed on “the information concerning the background, character, and conduct of a person convicted of an offense for the purpose of imposing an appropriate sentence.” See note 5 supra. Thus any exclusion must be based not merely upon the hearsay nature of the evidence but on its Due Process or Confrontation Clause implications.9
The Due Process Clause is plainly implicated at sentencing. E. g., Gardner v. Florida, 430 U.S. 349, 358, 97 S.Ct. 1197, 51 L.Ed.2d 393 (1977) (plurality); Williams v. New York, 337 U.S. 241, 252 n. 18, 69 S.Ct. 1079, 93 L.Ed. 1337 (1949); Townsend v. Burke, 334 U.S. 736, 740-41, 68 S.Ct. 1252, 92 L.Ed. 1690 (1948); see Note, Procedural Due Process at Judicial Sentencing for Felony, 81 Harv.L.Rev. 821, 825, 826 (1968). It does not necessarily follow, however, that all of the procedural safeguards and strict evidentiary limitations of a criminal trial proper are required. Gardner v. Florida, supra, 430 U.S. at 358 n. 9, 97 S.Ct. 1197, 51 L.Ed.2d 393. The Supreme Court has held quite to the contrary, specifically on the issue of hearsay in a presentence report. Williams v. New York, supra, held that it was not a denial of due process in sentencing to rely on information supplied by witnesses whom the accused could neither confront nor cross-examine.10
We must recognize that most of the information now relied upon by judges to

The Advisory Commission’s caveat to Fed.R. Evid. 1101(d) states: “The rule [excepting applicability of evidence rules to sentencing proceedings] is not intended as an expression as to when due process or other constitutional provisions may require an evidentiary hearing.” 56 F.R.D. 183, 351 (1972). Thus, the presumption of constitutionality which usually accompanies rulemaking, see Hanna v. Plumer, 380 U.S. 460, 471, 85 S.Ct. 1136, 14 L.Ed.2d 8 (1965), is inapplicable to the sentencing proceeding before us.

Contrary to the district court’s intimations, Williams v. New York, 337 U.S. 241, 69 S.Ct. 1079 (1949), has not been overruled by Gardner v. Florida, 430 U.S. 349, 97 S.Ct. 1197, 51 L.Ed.2d 393 (1977) (plurality). Gardner held that a defendant cannot be sentenced to death based on secret information in a presentence investigation report which he cannot dispute or *712explain because it is not disclosed to him. The Court noted that Williams' holding was not “directly applicable” because in Williams the facts contained in the report upon which the trial court relied were revealed to counsel in open court. Id. at 356, 97 S.Ct. 1197 (opinion of Stevens, J.). In this case, as in Williams, the defendant was apprised of all information proffered by the Government. Additionally, even if Gardner is interpreted as having qualified Williams, see 430 U.S. at 356-58, 362, 97 S.Ct. 1197 (opinion of Stevens, J.), there can be no doubt that its holding is strictly limited to due process guarantees in capital cases. See id. at 356, 359, 360; id. at 363-64, 97 S.Ct. 1197 (opinion of White, J.). See also Hollis v. Smith, 571 F.2d 685, at 692 (2d Cir. 1978). The district court also believed that Williams’ reasoning had been undercut by other recent Supreme Court cases. It relied heavily on pronouncements in parole, Morrissey v. Brewer, 408 U.S. 471, 489, 92 S.Ct. 2593, 33 L.Ed.2d 484 (1972), and probation revocation, Gagnon v. Scarpelli, 411 U.S. 778, 790, 93 S.Ct. 1756, 36 L.Ed.2d 656 (1973), contexts that due process requires that the prisoner be permitted to confront and cross-examine adverse witnesses. But see Wolff v. McDonnell, 418 U.S. 539, 567, 94 S.Ct. 2963, 41 L.Ed.2d 935 (1974) (to the contrary in prison disciplinary proceedings— loss of good time credit — because of “potential for havoc inside the prison walls”). While sentencing procedures may more closely resemble parole and probation revocations than loss of good time credit, as the court below found, it does not follow that all or even most out-of-court declarations must be subject to cross-examination in order to be admissible in a sentencing proceeding. Morrissey recognizes only a qualified right to confrontation of witnesses. At the parolee’s preliminary hearing, if the hearing officer finds that an informant would risk harm if his identity were revealed, confrontation and cross-examination are not mandated by due process. 408 U.S. at 487, 92 S.Ct. 2593. At the revocation hearing, confrontation and cross-examination are not required if the “hearing officer specifically finds good cause for not allowing confrontation.” Id. at 489, 92 S.Ct. at 2604. Similarly, the right to counsel articulated in Gagnon is determined on a case-by-case basis. 411 U.S. at 790, 93 S.Ct. 1756. Moreover, each stage of the criminal trial and post-conviction process must be examined independently in determining a defendant’s due process rights. See Wolff v. McDonnell, supra, 408 U.S. at 481, 94 S.Ct. 2963; Gagnon v. Scarpelli, supra, 411 U.S. at 788-89, 93 S.Ct. 1756.
