Bounsouay Thatsaphone was convicted in state court of third degree rape for engaging in sex with a minor. After the Supreme Court of South Dakota affirmed, Thatsa-phone petitioned for federal habeas corpus relief. The district court granted the writ, concluding that Thatsaphone because of his lack of English language skills had been subjected to in-custody interrogation in violation of his .constitutional rights under
Miranda v. Arizona,
In June 1993, Sioux Falls police detective Bruce Bailey investigated a complaint that twelve-year-old B.J.H. was the victim of a statutory rape. Bailey interviewed B.J.H., who identified Thatsaphone as the culprit. At Bailey’s request, Thatsaphone came to the police station for an untaped twenty-two minute interview during which he made incriminating admissions. Thatsaphone was indicted for statutory rape and moved to suppress his statements to Detective Bailey.
Following an evidentiary hearing, the trial judge made the following findings of fact. Thatsaphone is a Laotian immigrant who had lived in the United States for seven years and had worked at a local meat packing plant for six years. When Detective Bailey contacted him by telephone, Thatsaphone said he both spoke and understood English. On June 24, Thatsaphone voluntarily came to be interviewed by Bailey at the police station, accompanied by a friend, Vic Souvannarath, who also spoke English and Laotian. Bailey excluded Souvannarath from the interview “for several reasons including that [Thatsa-phone] told Bailey that he understood and spoke English pretty well, that [Thatsa-phone] appeared to Bailey to speak and understand English pretty well, that the friend by virtue of his relationship to [Thatsaphone] did not possess the requisite impartiality necessary for an appropriate and accurate interview, and that such friend was not certified by 911 communications as a recognized interpreter of the Laotian language.”
Before beginning the interview, Bailey asked Thatsaphone if he understood English. Thatsaphone explained that he had lived in the United States for seven years, had learned English at a local high school, and could speak and understand English pretty well. Bailey then told Thatsaphone that he was not under arrest and would not be placed under arrest that day, that the door to the interview room was closed for privacy but unlocked so he was free to leave, and that he could take restroom breaks at any time. Bailey asked Thatsaphone if he understood; Thatsaphone answered affirmatively. During the interview, Thatsaphone was anxious but not unusually so, Bailey did not use complicated terms or phrases, and Thatsa-phone “answered Bailey’s interview questions appropriately and by his answers appeared to understand such questions and the language thereof.” Bailey did not administer Miranda warnings at any time. The inter *1044 view lasted twenty-two minutes, following which Thatsaphone left the police station of his own accord. He was arrested the following day. At the evidentiary hearing, Thatsa-phone
testified before the Court [on] his Motion to Suppress and an interpreter was present throughout such hearing. Almost all of the testimony at said -hearing was an interchange directly between the respective attorneys asking questions in English and [Thatsaphone] speaking the answers in English. Neither attorney made any special effort to use simplistic words or phrases. [Thatsaphone] did not address the interpreter very often and ... only minor points of clarification were involved.... The English language was not a barrier to [Thatsaphone’s] understanding of all that was occurring at the hearing or Bailey’s interview.
Based upon these findings, the trial court denied Thatsaphone’s motion to suppress. After his conviction was affirmed, Thatsa-phone filed this petition for a writ of habeas corpus, arguing that his constitutional rights had been violated because the Bailey interview was custodial interrogation for Miranda purposes and his incriminating statements to Detective Bailey were involuntary. The district court on its own motion ordered an evidentiary hearing on the question of That-saphone’s understanding of the English language. At that hearing, three prison tutors testified that Thatsaphone’s English language skills were primitive when he was first incarcerated for this offense. Thatsaphone testified that he had understood almost nothing at the Bailey interview and the hearing on his motion to suppress. The magistrate judge recommended that the writ be granted on the ground that Thatsaphone’s statements should have been suppressed as involuntary. Without reaching the voluntariness issue, the district court granted the writ, concluding that Bailey’s interview was custodial interrogation, at which Miranda warnings were constitutionally required, because of Thatsa-phone’s “demonstrated limitations in understanding spoken English” and his “lack of familiarity with the American, legal system.” The State appeals, arguing that Thatsaphone was not in- custody and his admissions were voluntary.
I. The Miranda Issue
“Miranda
warnings are due only when a suspect interrogated by the police is ‘in custody.’ ”
Thompson v. Keohane,
Absent the English language issue, it is clear that Bailey’s twenty minute interview of Thatsaphone was not custodial interrogation. Indeed, the case would then be virtually on all fours with
Oregon v. Mathiason,
Any interview of one suspected of a crime by á police officer will have coercive' aspects to it.... But police officers are not required to administer Miranda warnings to everyone whom they question. Nor is the requirement of warnings to be imposed simply because the questioning takes place in the station house, or because the questioned person is one whom the police suspect. Miranda warnings are required *1045 only where there has been such a restriction on a person’s freedom as to render him “in custody.” It was that sort of coercive environment to which Miranda by its terms was made applicable, and to which it is limited.
That brings us to-the central issue in the ease, Thatsaphone’s understanding of the English language. Before discussing its merits, we must frame that issue and place it in its proper procedural context. We agree with the district court that a suspect’s language skills may be relevant to the “in custody” issue.
Cf. United States v. Ceballos,
Thus, the ultimate issue is whether a reasonable police officer conducting Detective Bailey’s otherwise non-custodial interview would have given
Miranda
warnings because he realized that the questioning would be perceived by Thatsaphone as custodial due to his limited English. language skills. This is a mixed question of constitutional law and fact which the federal habeas courts must review
due novo. See Thompson v. Keohane,
Second, the district court reasoned that an evidentiary hearing was needed “to develop the factual record,” and “to have an independent review of the constitutional issues.” As we have explained, Thatsaphone was not
entitled
to a second hearing in federal court because he failed to show cause excusing his failure to develop the
*1046
factual record in state court. The federal courts retain some discretion to hold non-mandatory evidentiary hearings in habeas cases.
Compare Clemmons v. Delo,
Returning now to the merits, we review the ultimate “in custody” issue
de novo. See Feltrop,
II. Voluntariness
The magistrate judge recommended that Thatsaphone’s statements to Detective Bailey were involuntary because, given Thatsaphone’s Laotian background, “merely summoning him to the police station, excluding him from his friend, and demanding information was sufficient coercion to overcome [his] resistance to confession.” Reviewing this recommendation
de novo, see United States v. Jacobs,
“Coercive police activity is a necessary predicate to the finding that a confession is not ‘voluntary’ within the meaning of the Due Process Clause of the Fourteenth Amendment.”
Colorado v. Connelly,
The judgment of the district court is reversed and the case is remanded with instructions to deny Thatsaphone’s petition for a writ of habeas corpus.
Notes
. The recent amendments to § 2254 enacted by the Antiterrorism and Effective Death Penalty Act of 1996 may limit this discretion to hold evidentiary hearings in habeas cases.
