Before PERRY, C.J., and McALLISTER, SLOAN, O'CONNELL, GOODWIN, DENECKE and RODMAN, JJ.
SLOAN, Justice.
Defendant was convicted of sodomy on his 15-year-old adopted daughter. Before trial, defendant moved the court to require the daughter and her mother to be examined by a psychiatrist. The "grounds" stated in the motion for requiring the examination stated "that nature of the charge makes this necessary since there is no evidence except complainant age 15 connecting defendant with commission of crime * * *." The motion was denied; renewed at the trial and again denied. The court's refusal to require the examination is the principal issue on appeal.
*117 Defendant urges that we adopt the rule stated by Wigmore that "No judge should ever let a sex-offence charge go to the jury unless the female complainant's social history and mental make-up have been examined and testified to by a qualified physician." 3 Wigmore, Evidence (3d ed. 1940) § 924a, p. 460. Wigmore's expressed concern for the peril to an innocent victim impaled by a lying or psychotic, neurotic or other mentally disturbed witness prompted him to make that assertion. Other writers and some courts have tended to follow Wigmore to the extent of allowing a discretionary power in the court to provide the means for a psychiatric examination of the complaining witness. McCormick, Evidence (1954) § 45, pp. 99, 100, and materials there cited; Comment, Psychiatric Evaluation of the Mentally Abnormal Witness, 1950, 59 Yale L.J. 1324; Juviler, Psychiatric Opinions as to Credibility of Witness, 1960, 48 Cal.L.Rev. 648. The authorities do not justify a mandatory rule. It was the intent of State v. Walgraeve, 1966, 243 Or. 328, 412 P.2d 23, 413 P.2d 609, to refuse a mandatory rule. Walgraeve was not intended to deprive the court of the authority to order the examination.
However, if we apply a permissive rule as in Ballard v. Superior Court, 1966, 64 Cal.2d 159, 176, 49 Cal. Rptr. 302, 313, 410 P.2d 838, 849, and also urged by defendant, it would not avail him in this case. For the California court decided that "Rather than formulate a fixed rule in this matter we believe that discretion should repose in the trial judge to order a psychiatric examination of the complaining witness in a case involving a sex violation if the defendant presents a compelling reason for such an examination.[*]" ([*] Footnote omitted). Some of the compelling reasons mentioned by the opinion were lack of corroboration and a showing of some evidence of mental or emotional instability of the complaining witness. Here there was no compelling reason stated in the motions and there was corroboration of the victim's testimony. In ruling on the pretrial motion the court actually considered the Ballard case and did exercise a meaningful and understanding discretion. There is, therefore, no basis provided by any of the authority relied on by defendant to reverse the trial court.[1]
The other assignments of error relate to questions the court has decided in many prior cases and do not merit discussion.
Affirmed.
