OPINION
Defendant was convicted of second degree murder. His appeal concerns the trial court’s grant of the State’s motion in limine, which forbade him from inquiring of the State’s key witness, Leonard Gallegos, with regard to the witness’s alleged participation in the notorious state penitentiary riots of 1980.
It was shown at the hearing on the motion that Gallegos voluntarily appeared and gave a statement to the police after he learned that his car had been identified at the scene of a stabbing murder. He admitted his presence, with others, and accused defendant of committing the crime. As a result of the information he gave, defendant was charged. We reverse.
The trial court was told that Gallegos was a former penitentiary inmate and had been under investigation regarding the penitentiary riots at the time he volunteered his statement implicating defendant and exculpating himself; that at the time the State filed its motion, Gallegos had been indicted on murder charges arising from the riots. Defense counsel argued at the hearing that Gallegos had a motive to lie because of the investigation and then-pending charges against himself, and the possibility of his own return to prison, and that defendant should be able to cross-examine on those matters to attack Gallegos’s credibility. The State responded that since Gallegos was not under indictment when he went to the police and gave the statement against defendant, he had no purpose to lie at that time. Without presentation of any evidence relating to the witness’s awareness of an investigation or pending charges against him, or his state of mind because of his own vulnerability to charges, the trial court granted the motion.
The State makes two responses to defendant’s appeal: (1) defendant did not cite a correct rule of evidence to support his opposition to the State’s motion, and (2) limitation of cross-examination is within the discretion of the trial court. Neither of those assertions adequately answers defendant’s contention that he had a constitutional right to confront the witness against him and to test that witness’s credibility by cross-examination that would show the witness’s motive to testify falsely.
Appellant relies strongly on Davis v. Alaska,
A more particular attack on the witness’ credibility is effected by means of cross-examination directed toward revealing possible biases, prejudices, or ulterior motives of the witness as they may relate directly to issues or personalities in the case at hand. The partiality of a witness is subject to exploration at trial, and is “always relevant as discrediting the witness and affecting the weight of his testimony.” 3A J. Wigmore, Evidence § 940, p. 775 (Chadbourn rev. 1970). We have recognized that the exposure of a witness’ motivation in testifying is a proper and important function of the constitutionally protected right of cross-examination. Greene v. McElroy,360 U.S. 474 , 496 [79 S.Ct. 1400 , 1413,3 L.Ed.2d 1377 ] (1959).
To deny that right of effective cross-examination was “constitutional error of the first magnitude” incurable by any amount of showing of lack of prejudice. Id. at 318,
Denial of the accused’s privilege of confronting a witness against him, in the discretion of the trial court, may not be an unconstitutional denial if the motive to falsify has already been presented by other means or other witnesses and the excluded cross-examination would do no more than develop cumulative evidence. State v. Lovato,
In Lovato, supra, a divided opinion, Chief Judge Wood recognized that the right to present evidence of a witness’s motive to give false testimony is not necessarily governed by the rules of evidence but by the broader authority of case law not inconsistent with the rules. That perception agrees with the Supreme Court’s analysis in Davis, supra; and despite two special concurrences in Lovato, supra, addressing the scope of the rules of evidence on cross-examination directed toward showing motive to lie, we are of the opinion that the comprehensiveness of cross-examination does not lie solely within the limitation of the rules. Compare N.M.R.Evid. 404(b), 607 and 609; and State v. Coca,
Several state and federal courts have considered the same question. State v. Hector,
Under the circumstances and facts of this case, we hold that it was improper for the trial court to grant the State’s motion to limit cross-examination of its principal witness against the defendant.
The conviction is reversed and the matter is remanded for a new trial.
