Petitioner-Appellant,
v.
NICHOLAS DEML, Commissioner, Vermont Department of Corrections,
Respondent-Appellee.
Appeal from the United States District Court for the District of Vermont No. 22-cv-140, William K. Sessions III, Judge.
Before: CHIN, SULLIVAN, and MERRIAM, Circuit Judges.
Petitioner-Appellant Robin O’Neill, who is serving a life sentence for a double homicide, appeals from a judgment of the United States District Court for the District of Vermont (Sessions, J.) dismissing her pro se petition for a writ of habeas corpus made pursuant to 28 U.S.C. § 2254. The district court dismissed O’Neill’s petition for failure to fully exhaust all her claims in the state courts. On appeal, O’Neill does not dispute that her “mixed” petition included both exhausted and unexhausted claims; instead, she argues that the district court erred because it did not inform her that she could have requested a stay of the exhausted claims or filed an amended petition that only included the exhausted claims. She also contends that the district court erred by failing to advise her of the one-year statute of limitations that applied to her exhausted claims under the Antiterrorism and Effective Death Penalty Act of 1996. We hold that the district court has no obligation to explain sua sponte to a pro se petitioner her options following the dismissal of her “mixed” habeas petition or the potential effects that such a dismissal could have on the timeliness of her claims. Accordingly, we AFFIRM the district court’s judgment.
AFFIRMED.

PER CURIAM:
Petitioner-Appellant Robin O’Neill, who is serving a life sentence for a
double homicide, appeals from a judgment of the United States District Court for
the District of Vermont (Sessions, J.) dismissing her pro se petition for a writ of
habeas corpus made pursuant to 28 U.S.C. § 2254. The district court dismissed
O’Neill’s petition for failure to fully exhaust all her claims in the state courts. On
appeal, O’Neill does not dispute that her “mixed” petition included both
exhausted and unexhausted claims; instead, she argues that the district court erred
2 because it did not inform her that she could have requested a stay of the exhausted
claims or filed an amended petition that only included the exhausted claims. She
also contends that the district court erred by failing to advise her of the one-year
statute of limitations that applied to her exhausted claims under the Antiterrorism
and Effective Death Penalty Act of 1996 (“AEDPA”). We hold that the district
court has no obligation to explain sua sponte to a pro se petitioner her options
following the dismissal of her “mixed” habeas petition or the potential effects that
such a dismissal could have on the timeliness of her claims. Accordingly, we
AFFIRM the district court’s judgment.
I. BACKGROUND
In 2017, a jury convicted Robin O’Neill of aggravated murder for killing her
ex-fiancé and his son. A state-court judge subsequently sentenced her to life in
prison. O’Neill appealed her conviction, which the Vermont Supreme Court
affirmed. O’Neill then filed a petition seeking post-conviction relief in the
Vermont Superior Court, arguing that her counsel provided her with ineffective
assistance. She subsequently amended her state petition in 2021, again asserting
ineffective assistance of counsel.
While that petition was pending before the state court, O’Neill filed, pro se,
the federal petition now at issue in this appeal. In that petition, O’Neill asserted 3 a variety of constitutional challenges, including the claim of ineffective assistance
of counsel that was pending before the Vermont Superior Court. The district
court dismissed O’Neill’s mixed petition, concluding that O’Neill’s inclusion of
unexhausted claims barred her federal petition. See App’x at 317; see also 28
U.S.C. § 2254(b)(1)(A) (“An application for a writ of habeas corpus on behalf of a
person in custody pursuant to the judgment of a State court shall not be granted
unless it appears that the applicant has exhausted the remedies available in the
courts of the State.”). O’Neill timely appealed, arguing that the district court
erred by failing to (1) provide her with “an appropriate explanation . . . of her
available options and the consequences” of filing a mixed petition for a writ of
habeas corpus, and (2) explain “the effect of a dismissed mixed petition on time-
barred and unexhausted claims.” O’Neill Br. at 2.
II. DISCUSSION
In reviewing a district court’s dismissal of a habeas petition, we review the
district court’s legal conclusions de novo. See, e.g., Vega v. Schneiderman, 861 F.3d
72, 74 (2d Cir. 2017). 1
1 Although the parties suggest that we should review the district court’s dismissal for abuse of discretion, the questions presented in this appeal are legal ones – i.e., whether a district court has a legal obligation to sua sponte inform a pro se petitioner of her options upon the filing of a mixed
4 Until AEDPA was enacted in 1996, whenever a state prisoner submitted a
mixed petition for a writ of habeas corpus with a federal district court, the “district
court [was required to] dismiss [the] mixed petition[], leaving the prisoner with
the choice of returning to state court to exhaust [her] claims or of amending or
resubmitting the habeas petition to present only exhausted claims to the district
court.” Rose v. Lundy, 455 U.S. 509, 510 (1982) (internal quotation marks omitted).
Following the enactment of AEDPA, the Supreme Court permitted federal courts
to “stay and abey” such mixed petitions, whereby the district court would dismiss
any unexhausted claims from the mixed petition, stay the remaining exhausted
claims, and permit the petitioner to subsequently amend the original petition to
add the newly exhausted claims at the conclusion of the state-court proceedings.
See Pliler v. Ford, 542 U.S. 225, 230–31 (2004); see also Rhines v. Weber, 544 U.S. 269,
277 (2005) (approving the stay-and-abeyance procedure under certain
circumstances).
On appeal, O’Neill argues that the district court should have explained all
the options available to her “so that she could make an informed decision [about]
whether to press the []exhausted claims in the district court, withdraw the
petition or the effects the dismissal of that petition could have on her claims. Accordingly, we review them de novo. 5 unexhausted claims, or request a stay of the proceedings” pending the exhaustion
of those claims in state court. O’Neill Br. at 11–12. In essence, O’Neill contends

any unexhausted claims from the mixed petition, stay the remaining exhausted

See Pliler v. Ford, 542 U.S. 225, 230–31 (2004); see also Rhines v. Weber, 544 U.S. 269,
277 (2005) (approving the stay-and-abeyance procedure under certain
circumstances).
On appeal, O’Neill argues that the district court should have explained all
the options available to her “so that she could make an informed decision [about]
whether to press the []exhausted claims in the district court, withdraw the
petition or the effects the dismissal of that petition could have on her claims. Accordingly, we review them de novo. 5 unexhausted claims, or request a stay of the proceedings” pending the exhaustion
of those claims in state court. O’Neill Br. at 11–12. In essence, O’Neill contends
that the district court was obliged to sua sponte explain both what course of action
she could take upon filing a mixed habeas petition and the potential consequences
that the court’s dismissal of that petition could have on her claims. According to
O’Neill, such explanations would align with the principle that there is “an
obligation on the part of the court to make reasonable allowances to protect pro se
[petitioners] from inadvertent forfeiture of important rights because of their lack
of legal training.” Id. at 15–16 (quoting Traguth v. Zuck, 710 F.2d 90, 95 (2d Cir.
1983)).
To be sure, we have previously recognized that “[i]f a district court elects
. . . [to] dismiss[] the entire petition, it should normally include in the dismissal
order an appropriate explanation to a pro se petitioner of the available options and
the consequences of not following required procedures.” Zarvela v. Artuz, 254
F.3d 374, 382 (2d Cir. 2001). But since our decision in Zarvela, the Supreme Court
has rejected the contention that district courts must provide such explanations,
holding “that federal district judges are not required to give pro se litigants”
detailed warnings about their options when they file mixed petitions or about the
6 potential effects that dismissal of such petitions could have on their claims. Pliler,
542 U.S. at 231-33. Therefore, to the extent our language in Zarvela could be read
to impose a legal obligation on district courts to advise pro se petitioners of their
options and the consequences of filing a mixed petition, that obligation no longer
exists after Pliler.
It bears noting that Pliler involved a fact pattern that is strikingly similar to
the one at issue here. In Pliler, the pro se petitioner filed a mixed petition, which
the district court dismissed without first explaining to the petitioner that (1) he
could choose to dismiss his unexhausted claims, stay his petition until he
exhausted his unexhausted claims in state court, and then amend his petition once
all his claims were exhausted, and (2) any subsequent petition, i.e., one that was
not stayed by the district court, would likely be time-barred under AEDPA’s one-
year statute of limitations. See id. at 228–31. Although the Ninth Circuit held
that the district court committed reversible error by not providing such guidance
to the petitioner, the Supreme Court reversed, holding that “a defendant does not
have a constitutional right to receive personal instruction from the trial judge on
courtroom procedure” and that “the Constitution does not require judges to take
over chores for a pro se defendant that would normally be attended to by trained
7 counsel as a matter of course.” Id. at 231 (alterations accepted and internal
quotation marks omitted). The Court also warned that “[r]equiring district courts
to advise a pro se litigant” in the manner proposed by the Ninth Circuit – that is,
by “[e]xplaining the details of federal habeas procedure and calculating statutes of
limitations” – “would undermine [the] district [judge’s] role as [an] impartial
decisionmaker[].” Id.
In light of Pliler’s clear language, we now join both the Sixth and Ninth
Circuits in holding that district courts are under no obligation to sua sponte advise
pro se petitioners of their options upon filing a mixed petition or the effects that the
dismissal of such a petition could have on their claims. 2 See Robbins v. Carey, 481
F.3d 1143, 1148 (9th Cir. 2007) (“Pliler makes it clear that district courts are not
required to consider sua sponte the stay-and-abeyance procedure. Such a
mandatory action by the trial judge falls within the set of ‘chores’ targeted by the
Supreme Court in Pliler.”); McBride v. Skipper, 76 F.4th 509, 514 (6th Cir. 2023)
2 Although we hold that courts in this Circuit are not required to provide this advice, we note that they nevertheless may do so, especially when the advice given serves to alert a petitioner generally of the constraints imposed by AEDPA, as opposed to the merits of the various options. See Zarvela, 254 F.3d at 382 (“[T]he dismissal order might usefully advise the petitioner of his option to drop his unexhausted claims and resubmit a petition containing only his exhausted claims, or to exhaust his unexhausted claims in state court and then return to federal court. It would also be useful to alert the petitioner to the one-year limitations period of AEDPA and to the fact that a portion of that period has already elapsed.”).
8 (“Federal district court judges have ‘no obligation’ to warn a pro se petitioner about
how a circuit’s stay-and-abey procedure or AEDPA’s [one]-year statute of
limitations would impact [her] mixed petition.” (quoting Pliler, 542 U.S. at 231)).
Accordingly, we cannot say that the district court erred in dismissing O’Neill’s
petition without first explaining her stay-and-abey options or the potential effects
of the district court’s dismissal on her subsequently filed claims. 3
III. CONCLUSION
For all the foregoing reasons, we AFFIRM the judgment of the district court.
