concurring:
If information protected by the attorney-client privilege is disclosed by compulsion, or by inadvertence even with the exercise of due care, difficult questions arise as to whether or not the privilege remains. Discussion of the subject has not been extensive, although language in some of the cases would indicate that in either circumstance the privilege would remain. United States v. Grammer, 513 F.2d 673, 676 (9th Cir. 1975); United States v. Gurtner, 474 F.2d 297, 299 (9th Cir. 1973); In re Horowitz, 482 F.2d 72, 81-82 (2d Cir.), cert. denied, 414 U.S. 867, 94 S.Ct. 64, 38 L.Ed.2d 86 (1973); see 8 Wigmore, Evidence § 2326 (McNaughton rev. 1961). I agree with the court that in the special circumstances of the instant ease there was no waiver of the privilege, and I concur in the judgment.
