Appellant Jose Mercedes Amparo pled guilty to attempting to bring illegal aliens into the United States in violation of 8 U.S.C. § 1324(a)(1)(A). He claims that the twenty-four month prison term imposed by the district court was disproportionately severe and premised on an improper upward departure. We remand for resentencing due to the government's breach of its plea agreement obligation to recommend a sentence within the applicable guideline sentencing range ("GSR").I

On September 27, 1991, the United States Border Patrol intercepted a 38-foot yawl carrying ninety-five illegal aliens from the Dominican Republic to Aguadilla, Puerto Rico, which is not a designated port of entry into the United States. Border Patrol agents found neither food nor water aboard the vessel, nor did they find life jackets, safety or emergency equipment, sanitary facilities, or a radio for communication. Appellant was identified as a captain of the vessel and arrested. The co-captain was arrested as well, and both men were indicted under 8 U.S.C. § 1324(a)(1)(A).

Appellant entered into a plea agreement whereby he would plead guilty to one count, in return for the government's recommendation of a sentence within the applicable GSR and dismissal of the two remaining counts. At sentencing, the district court assigned a base offense level of nine for the offense of conviction under 8 U.S.C. § 1324(a)(1)(A), see U.S.S.G. § 2L1.1(a)(2), which was reduced by two levels for acceptance of responsibility, then offset by a two level increase because appellant, as a captain of the vessel, provided a special skill to facilitate the commission of the offense, see U.S.S.G. § 3B1.3. The adjusted offense level of nine, combined with a category I criminal history, yielded a 4-to-10 month GSR. The court decided to depart upward to offense level fifteen, which resulted in an 18-to-24 month GSR, then sentenced appellant to a twenty-four month prison term.

At oral argument on appeal, appellant asserted for the first time that the government had breached an express provision in the plea agreement by not recommending a sentence within the 4-to-10 month GSR. Government counsel conceded that no such recommendation had been made. Moreover, we note, sua sponte, that the presentence report ("PSR") misstates the pertinent provision in the plea agreement.1

"Plea bargaining is a fundamental part of our criminal justice system ...," Correale v. United States, 479 F.2d 944, 947 (1st Cir.1973), but though it promotes efficiency and expedition in the administration of criminal proceedings, its benefits "flow ... from the defendant's waiver of almost all the constitutional rights we deem fundamental. There must accordingly be safeguards to insure that the waiver is knowledgeable ... and voluntary...." Id. (citing Boykin v. Alabama, 395 U.S. 238, 89 S. Ct. 1709, 23 L. Ed. 2d 274 (1969), and Machibroda v. United States, 368 U.S. 487, 82 S. Ct. 510, 7 L. Ed. 2d 473 (1962)). "Though a legitimate prosecution promise does not render a guilty plea legally involuntary, Brady v. United States, 397 U.S. 742, 90 S. Ct. 1463, 25 L. Ed. 2d 747 (1970), its fulfillment is a necessary predicate to a conclusion of voluntariness when a plea 'rests in any significant degree' on it." Correale, 479 F.2d at 947 (quoting Santobello v. New York, 404 U.S. 257, 262, 92 S. Ct. 495, 499, 30 L. Ed. 2d 427 (1971)).

Ordinarily, "an issue not presented in the district court will not be addressed for the first time on appeal." United States v. Curzi, 867 F.2d 36, 44 (1st Cir.1989). See also United States v. Fox, 889 F.2d 357, 359 (1st Cir.1989); United States v. Figueroa, 818 F.2d 1020, 1025 (1st Cir.1987); United States v. Argentine, 814 F.2d 783, 791 (1st Cir.1987). An appellate court nevertheless has the discretionary power, in an exceptional case, to resolve an issue not passed on below. Singleton v. Wulff, 428 U.S. 106, 121, 96 S. Ct. 2868, 2877, 49 L. Ed. 2d 826 (1976). See United States v. La Guardia, 902 F.2d 1010, 1013 (1st Cir.1990); United States v. Krynicki, 689 F.2d 289 (1st Cir.1982). Although the discretionary appellate power to consider an unpreserved issue should be exercised sparingly, La Guardia, 902 F.2d at 1013, it is appropriately invoked if " 'injustice might otherwise result.' " Singleton, 428 U.S. at 121, 96 S.Ct. at 2877 (quoting Hormel v. Helvering, 312 U.S. 552, 557, 61 S. Ct. 719, 722, 85 L. Ed. 1037 (1941)).

The issue belatedly raised on appeal exhibits characteristics which we have considered sufficiently exceptional to warrant appellate review in other cases. The issue is one of law, as there is no dispute that the plea agreement was breached; and the issue is susceptible of resolution on the present record. See Krynicki, 689 F.2d at 291; see also La Guardia, 902 F.2d at 1013. Moreover, due to the nature of the breach, the only question remaining is the appropriate remedy. See Krynicki, 689 F.2d at 292; see also La Guardia, 902 F.2d at 1013. Finally, appellate deferral of the belated claim would not "aid the administration of the criminal justice system," see Krynicki, 689 F.2d at 292; see also La Guardia, 902 F.2d at 1013, and, most importantly, it might well result in a miscarriage of justice in the present case. See Singleton, 428 U.S. at 121, 96 S.Ct. at 2877; La Guardia, 902 F.2d at 1013; Krynicki, 689 F.2d at 292.

There is no conceivable basis for concluding that the government's promise to recommend a sentence within the GSR was not a significant factor in inducing appellant's plea. See Correale, 479 F.2d at 947. Moreover, the material misstatement in the PSR--that the government would make no sentencing recommendation--may well have misled the district court to believe that the government was under no duty to recommend a sentence within the GSR. In these circumstances, we are not prepared to assume either that the government's commitment to recommend a sentence within the GSR was a matter of no significance in obtaining appellant's guilty plea, see id., or that the court would not have given serious consideration to the government's sentencing recommendation had it been made. Thus, we cannot exclude all likelihood that appellant's waiver of constitutional rights lacked the requisite voluntariness, see Correale, 479 F.2d at 947, or that our failure to address the issue would result in a miscarriage of justice. See Singleton, 428 U.S. at 121, 96 S.Ct. at 2877 (appellate resolution of unpreserved issue may be appropriate where injustice would otherwise result).2

The undisputed breach of a core provision in the plea agreement, requiring the government to recommend a sentence within the GSR, must be remedied.3 Normally, a plea bargain breach by the government may be remedied either through specific performance of the unperformed provision or by allowing the defendant to withdraw the plea and proceed to trial. Kingsley v. United States, 968 F.2d 109, 133 (1st Cir.1992); United States v. Canada, 960 F.2d 263, 271 (1st Cir.1992); see Santobello v. New York, 404 U.S. 257, 263, 92 S. Ct. 495, 499, 30 L. Ed. 2d 427 (1971). "In choosing a remedy, a court must exercise its 'sound discretion ... under the circumstances of each case.' ... Specific performance, the less extreme remedy, is preferred." Kingsley, 968 F.2d at 113 (citations omitted) (quoting United States v. Garcia, 698 F.2d 31, 37 (1st Cir.1983)).

We believe specific performance is appropriate in these circumstances. Although it misapprehends the nature of the breach,4 appellant's request for "resentencing with the express instruction that appellant be sentenced within the [GSR]" indicates appellant's preference for specific performance, rather than withdrawal of the plea. Moreover, the choice of remedy rests with the court, not with the defendant. Kingsley, 968 F.2d at 113; Canada, 960 F.2d at 271. As specific performance would not be "meaningless" in these circumstances, see id. at 114, but more appropriate than other remedies we might fashion, we vacate the sentence and remand for resentencing before a different judge in accordance with our normal practice. See Canada, 960 F.2d at 271 (remanding for resentencing before a different judge to remedy government's plea bargain breach).

Vacated and remanded for resentencing.
