STATE of North Carolina
v.
Jack Gordon GREENE.
No. 405A92.
Supreme Court of North Carolina.
January 28, 1994.
*744 Michael F. Easley, Atty. Gen. by Jeffrey P. Gray, Asst. Atty. Gen., Raleigh, for the State.
Malcolm Ray Hunter, Jr., Appellate Defender by Gordon Widenhouse, Asst. Appellate Defender, Raleigh, for defendant-appellant.
WHICHARD, Justice.
Defendant was tried capitally and convicted of the first-degree murder of his brother, Turner Buette Greene, Jr. Defendant, who was indigent, moved pre-trial for an ex parte hearing at which to present evidence to support his request for a psychological or psychiatric expert to aid in his defense. The trial court denied the motion. We hold that this ruling violated defendant's rights under the United States Constitution based on our prior holdings in State v. Ballard, 333 N.C. 515, 428 S.E.2d 178, cert. denied, ___ U.S. ___, 114 S.Ct. 487, 126 L.Ed.2d 438 (1993), and State v. Bates, 333 N.C. 523, 428 S.E.2d 693, cert. denied, ___ U.S. ___, 114 S.Ct. 487, 126 L.Ed.2d 438 (1993). The United States Supreme Court denied certiorari in both Ballard and Bates on 15 November 1993.
On 19 December 1991 defendant moved for an ex parte hearing at which he would apply for funds to obtain expert witnesses for his defense. The trial court denied the motion. On 24 February 1992 defendant moved for a psychological evaluation by a psychologist or psychiatrist and requested that the motion be heard ex parte. In support of his motion, defendant cited his past treatment for alcoholism, his hospitalization for emotional behavior, and his increased use of alcohol and drugs during the year of the offense. Defendant also noted his troubled family history, including his father's suicide when defendant was less than two years old and his mother's death from an overdose of medication. Defendant previously had stated that Turner Greene, Jr., the victim here, caused their mother's death. Defendant's trial counsel argued that the ex parte hearing was necessary because defendant would divulge important defense tactics in support of his motion. The trial court denied his request for an ex parte hearing and his motion for funds for a psychological or psychiatric expert.
We agree with defendant that an ex parte hearing on his Motion for Psychological Evaluation was required. We addressed a similar situation in Ballard. There the noncapital defendant moved for an ex parte hearing at which to present evidence in camera to support his request for the appointment of a psychiatric expert. We held that the denial of the defendant's motion was constitutional error that entitled him to a new trial. Ballard, 333 N.C. at 516, 428 S.E.2d at 179. Though the defendant in Ballard was tried non-capitally, the same reasoning applies to capital defendants. See Bates, 333 N.C. at 527-28, 428 S.E.2d at 695 (awarding capital defendant a new trial based on denial of motion for ex parte hearing for appointment of forensic psychologist). In Ballard we stated that if a hearing in which an indigent defendant seeks the assistance of a psychiatric expert is held in the presence of the State, the defendant's insanity or other defense strategy is impermissibly exposed. Ballard, 333 N.C. at 519, 428 S.E.2d at 180. Further, when the State is present at a hearing that focuses on the defendant's lack of mental stability, the defendant's inclination to reveal all relevant evidence may be stymied. Such a hearing violates defendant's right against self-incrimination guaranteed by the Fifth Amendment to the United States Constitution because to obtain psychiatric assistance defendant is compelled to *745 make statements that he would not otherwise voluntarily make before the State. Id. at 520-21, 428 S.E.2d at 181-82. A hearing for funds for a psychiatric expert held in the presence of the State also violates defendant's right to effective assistance of counsel guaranteed by the Sixth Amendment to the United States Constitution. Id. at 521-22, 428 S.E.2d at 181-82. For these reasons, the trial court erred in denying defendant's motion for an ex parte hearing.
We note that Ballard and Bates had not been decided when this case was tried. The trial court thus could not have taken their holdings into account when making its ruling here.
We cannot know what evidence defendant would have presented at an ex parte hearing. Without that knowledge, we cannot deem the error here harmless beyond a reasonable doubt. N.C.G.S. § 15A-1443(b) (1988); see Ballard, 333 N.C. at 523, 428 S.E.2d at 183; Bates, 333 N.C. at 527-28, 428 S.E.2d at 695. Accordingly, defendant is entitled to a new trial.
Defendant's remaining assignments of error are unlikely to recur upon retrial. We therefore need not consider them.
NEW TRIAL.
