This original proceeding concerns the permissible scope of discovery by the prosecution in a criminal case.
Petitioner is charged with assault with a deadly weapon (Pen. Code, § 245, subd. (a)). The district attorney moved for “pretrial discovery.” His motion was supported by his аffidavit that the alleged victim and a witness of the alleged assault had been interviewed by and hаd talked to an investigator for defendant or his attorneys. Defendant opposed the mоtion. The trial court ordered defense counsel to- (1) “make available for inspection and copying to the District Attorney . . . any and all statements in your possession or availаble to you obtained from” the named witnesses, another person not shown by the affidavit to hаve been interviewed by the defense, “and any other witnesses other than the defendant”; (2) make similarly available “the names, addresses and statements of any witnesses other than the defеndant which the attorneys for the defendant intend to call for the purpose of raising an affirmative defense.” The order also provided (3) that it “is a continuing one, and in the event any material described in the above paragraphs becomes available to the dеfendant’s attorneys subsequent to the signing of this order” they shall “make the names, addresses and statеments of the witnesses available” to the prosecution. Petitioner sought prohibition or mandate from us, and we issued both alternative writs. We have concluded that prohibition is the aрpropriate remedy. The alternative writ of mandate is therefore discharged.
We first reject petitioner’s attack upon those portions of the order which are not limitеd to an “affirmative defense.” It is quite true that the leading case
(Jones

is not removed by
Pike.
Portions of the order before us require revеlation of the names of
*635
‘‘any witnesses other than defendant,” without limitation to those defendаnt intends to call. As pointed out in
Jones
(
Jones also strictly limited prosecution disсovery of written materials to those the defendant intends to introduce in evidence at trial. That case dealt with physicians’ reports upon a physical fact which could be еstablished by medical evidence. Even within that restricted sphere, Jones limited discovery to those reports which the defense intended to introduce. It carefully struck down those portions of the discovery order not so limited because they would require defendant to give the prosecution “the benefit of his knowledge of . . . the existence of possible reports . . . for the purpose of preparing its case against him. ’ ’ (P. 60.)
Jones
emphasizes (58 Cal.2d at pp. 60-62) that discovery cannot infringe upon the privilege against self-incrimination or upon the attorney-cliеnt privilege. It strikes a balance by requiring defendant to disclose, before trial, “information that he will shortly reveal anyway” (p. 62). Nothing in
Pike
eliminates this restriction. That case establishes the right to “require defense counsel to supply names and addresses and expected testimony оf defense witnesses,” without limitation to “affirmative” defenses. But in describing this as information which “would necessarily be disclosed at the trial” (
The present order goes beyond permissible limits by apparently requiring disclosure of a.ll statements of any witnesses interviewed by defense counsel, whether or not the defense intends to introduce such statements.
Insofar as the order before us requires petitioner to reveal the names and addresses of witnesses he intends to cаll, and *636 written material he intends to offer in evidence, it is permissible. To the extent that it excеeds those limits, the order cannot stand.
Let peremptory writ of prohibition issue restraining the trial court from proceeding in a manner inconsistent with the views expressed herein.
Brown (H. C.), J., and Caldecott, J., concurred.
Petitioner’s application for a hearing by the Supreme Court was denied October 22, 1969.
