Fabian-Baltazar pleaded guilty to possession of 50 grams or more of methamphetamine with intent to distribute, in violation of 21 U.S.C. § 841(a)(1) and (b)(1)(A), after entering into a plea agreement waiving the right to appeal or collaterally attack his sentence. Fabian-Baltazar *1217nonetheless filed a 28 U.S.C. § 2255 motion attacking the sentence, claiming among other things that trial counsel rendered ineffective assistance by failing to file a notice of appeal.
The district court denied the § 2255 motion, and this Court affirmed, holding that the district court did not err by enforcing Fabian-Baltazar's "express waiver of his right to bring a 28 U.S.C. § 2255 petition." United States v. Fabian-Baltazar , 707 F. App'x 477, 478 (9th Cir. 2017). We noted that a plea agreement that waives the right to collateral review is unenforceable with respect to an ineffective assistance claim challenging the voluntariness of the waiver, but stressed that Fabian-Baltazar's § 2255 motion did not challenge the voluntariness of his collateral review waiver. Id .
Fabian-Baltazar petitioned for certiorari. The Supreme Court granted the petition, vacated the judgment, and remanded for further consideration in light of Garza v. Idaho , --- U.S. ----, 139 S. Ct. 738, 203 L.Ed.2d 77 (2019). See Fabian-Baltazar v. United States , --- U.S. ----, 139 S. Ct. 1289, 1289, 203 L.Ed.2d 412 (2019). We then ordered the parties to file supplemental briefs addressing Garza . Having considered that briefing, we vacate the order of the district court and remand for further proceedings.
I
In Garza , the Supreme Court held that an attorney provides ineffective assistance by failing to file a notice of appeal after a client request that the attorney do so, even if that client has signed an appeal waiver. 139 S. Ct. at 747. Under Strickland v. Washington , a successful claim for ineffective assistance requires not only proof of deficient performance, but also resulting prejudice. 466 U.S. 668, 687-88, 692, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). But, in Garza , the Court held that prejudice is presumed when the defendant is deprived of an appeal that he waived but nonetheless tried to assert. 139 S. Ct. at 749.
Unlike Garza, Fabian-Baltazar also waived his right to collaterally attack his sentence. But, the government has declined to enforce Fabian-Baltazar's collateral attack waiver on remand. Therefore, in contrast to the first time this case was before us, we must analyze it as involving only an appeal waiver.
II
The parties agree that a remand is required in light of Garza but disagree about the scope of the remand. Fabian-Baltazar argues that we should simply reverse the district court's order and direct it to address the merits of his § 2255 motion. The government argues that, before proceeding to the merits, the district court must first determine whether Fabian-Baltazar requested his attorney to file a notice of appeal.
The government's view is in accord with Garza , which held that "Garza's attorney rendered deficient performance by not filing the notice of appeal in light of Garza's clear requests ." 139 S. Ct. at 746 (emphasis added); see also id. ("We have long held that a lawyer who disregards specific instructions from the defendant to file a notice of appeal acts in a manner that is professionally unreasonable.") (quoting Roe v. Flores-Ortega , 528 U.S. 470, 477, 120 S.Ct. 1029, 145 L.Ed.2d 985 (2000) ). It appears to have been uncontested in Garza that the defendant had requested his attorney to file a notice of appeal. 139 S. Ct. at 743, 746. But, the Court expressly left "undisturbed today Flores-Ortega 's separate discussion of how to approach situations in which a defendant's wishes are less clear." 139 S. Ct. at 746 n.9.
*1218Because that discussion governs our analysis today, we quote it in pertinent part:
If counsel has consulted with the defendant, the question of deficient performance is easily answered: Counsel performs in a professionally unreasonable manner only by failing to follow the defendant's express instructions with respect to an appeal. If counsel has not consulted with the defendant, the court must in turn ask a second, and subsidiary, question: whether counsel's failure to consult with the defendant itself constitutes deficient performance.
Flores-Ortega , 528 U.S. at 478, 120 S.Ct. 1029 (internal citation omitted).
Fabian-Baltazar's § 2255 motion contends that he expressly instructed his attorney to file a notice of appeal. But, the government has never had the opportunity to challenge that assertion, because both the district court's and this Court's prior rulings held that the collateral attack waiver nonetheless barred the § 2255 motion. The district court therefore should determine on remand whether such an instruction was given, and if not, whether counsel failed to consult, and if so, whether that failure constituted deficient performance. See United States v. Sandoval-Lopez , 409 F.3d 1193, 1198 (9th Cir. 2005) ("If a defendant, even one who has expressly waived his right to appeal, files a habeas petition after sentencing and judgment claiming that he ordered his attorney to appeal and his attorney refused to do so, two things can happen. The district court can hold an evidentiary hearing to decide whether petitioner's allegation is true, and if it is, vacate and reenter the judgment, allowing the appeal to proceed. Or, if the state does not object, the district court can vacate and reenter the judgment without a hearing and allow the appeal to proceed, assuming without deciding that the petitioner's claim is true."); see also Flores-Ortega , 528 U.S. at 478, 120 S.Ct. 1029 ("We employ the term 'consult' to convey a specific meaning-advising the defendant about the advantages and disadvantages of taking an appeal, and making a reasonable effort to discover the defendant's wishes.").
III
For the reasons above, we VACATE the order of the district court and remand for further proceedings consistent with this opinion.
