JOHN LEWIS SMITH, Jr., District Judge.
Defendants have moved for a pre-trial psychiatric examination of the witness Robert Earl Barnes. The principal case cited in support of such a course of action is State v. Butler, 27 N.J. 560, 143 A.2d 530 (1958). Other authorities cited bear on the admissibility of psychiatric testimony at trial and the propriety of pre-trial psychiatric examination of the complaining witness in sex offense cases, and as such are not in point, cf. United States v. Hiss, 88 F. Supp. 559 (S.D.N.Y.1950), Ballard v. Superior Court of San Diego County, 64 Cal.2d 159, 49 Cal.Rptr. 302, 410 P.2d 838 (1966).
It is well established that the grant or denial of the motion in question is within the discretion of the trial judge. In State v. Butler, supra, the court stated at page 556:
Manifestly, a practice of granting psychiatric examination of witnesses must be engaged in with great care. Orders to permit it to be done should be executed only upon a substantial showing of need and justification. * * * Much reliance must be placed upon the judgment of the trial court in the individual case.
