*389 Opinion
The People appeal following the dismissal of the information against respondent Paul McNally after a determination that McNally had been previously placed in jeopardy for the same charge. Respondent was charged with kidnaping (Pen. Code, § 207), forcible rape (Pen. Code, § 261, subd. 2), rape by threat of great bodily harm (Pen. Code, § 261, subd. 3), and forcible oral copulation (Pen. Code, § 288a). It was alleged that in the commission of the last three offenses, respondent used a deadly weapon, a metal pipe (Pen. Code, § 12022, subd. (b)), and that he inflicted great bodily injury during commission of the rapes (Pen. Code, § 12022.7).
Prior to trial appellant’s attorney, Deputy Public Defender H. Sinclair Kerr, became aware that his office had previously represented the victim in this case in a misdemeanor matter. Kerr decided this prior representation did not amount to a conflict of interest.
On March 19, 1979, trial commenced and the jury was selected. During the trial Kerr became aware that the public defender’s office had represented the victim in at least two other misdemeanor cases. After further consultation with his office and a review of the various case files, Kerr determined that in fact a conflict of interest did exist. On the third day of trial, Kerr explained the conflict to the court and asked to be relieved. The court declared itself satisfied that there was a conflict of interest, and expressed the view that it had no other choice but to relieve Kerr as attorney for defendant. The court then declared a mistrial.
Prior to the date set for the second trial, respondent filed a notice of motion for an order entering a plea of once in jeopardy. After a hearing, the plea was sustained and the information was dismissed. The court found that respondent did not consent to the mistrial, and that there was no legal necessity for its granting. We disagree. For reasons which we will discuss, we conclude that legal necessity required this mistrial, and that respondent’s consent was unnecessary under these circumstances. 1

It is well settled that (1) a person is in legal jeopardy for an offense when placed on trial in a court of competent jurisdiction, on a valid accusatory pleading, before a jury duly impaneled and sworn, and that (2) discharge of that jury without a verdict is equivalent to acquittal and bars a retrial, unless the defendant consented to the discharge or legal necessity required it.
(Curry
v.
Superior Court
(1970)
The general rule is that legal necessity for a mistrial arises from an inability of the jury to agree, or from physical causes beyond the control of the court, such as the death, illness, or absence of judge or juror, or of the defendant. A mere error of law or procedure, even a “palpably prejudicial error” in an evidentiary ruling, does not constitute legal necessity.
(Larios
v.
Superior Court
(1979)
As the court stated in
Larios
(at p. 330): “‘A defendant may choose not to move for or consent to a mistrial for many reasons. He may be of the opinion that no error in fact occurred, or if it occurred, that it was not prejudicial.... Indeed, even when a palpably prejudicial error has been committed a defendant may have valid personal reasons to prefer going ahead with the trial rather than beginning the entire process anew, such as a desire to minimize the embarrassment, expense, and anxiety [involved in being prosecuted]. These considerations are peculiarly within the knowledge of the defendant, not the judge, and the latter must avoid depriving the defendant of his constitutionally protected freedom of choice in the name of paternalistic concern for his welfare.’
(Curry, supra,
at p. 717.)” (See also

v.
Compton
(1971)
We must decide, therefore, whether this conflict of interest, discovered and announced in midtrial, amounted to legal necessity for a mistrial, or whether it was a development akin to an error of law or procedure requiring the defendant’s consent before a mistrial could be declared. Initially, we observe that respondent does not dispute that a disabling conflict of interest existed as to his original trial counsel, requiring the appointment of substitute counsel. The thrust of respondent’s contention here is that such conflict of interest does not mandate a mistrial and that absent respondent’s effective consent, his retrial is precluded.

The absence of a defendant’s attorney was at issue in
People
v.
Manson
(1976)
Here, too, the development which led to the mistrial was not simply a legal or procedural error; rather, counsel’s belated discovery of his conflict of interest struck at respondent’s constitutionally guaranteed right to assistance of counsel. (U.S. Const., 6th Amend.; Cal. Const., art. I, § 15.) If counsel must represent conflicting interests or is ineffective because of the burdens of representing more than one defendant, the injured defendant has been denied his constitutional right to effective counsel.

v.
Chacon
(1968)
Respondent urges here that instead of declaring a mistrial, the court should have appointed a substitute attorney, granted a recess and resumed the trial at a later date. Respondent cites
Hutson
v.
Superior Court
(1962)
Furthermore, respondent’s proposed solution, though possible, is not feasible as a practical matter. Substitution of counsel at trial would necessarily result in new counsel being required to fully familiarize himself with the facts of the case, a task which would include reinterview *393 ing witnesses. It would be necessary to obtain a transcript of all prior proceedings, including the testimony to date at the trial, the opening statements, if any, and probably the jury voir dire. The delay incident to this process would be substantial. Recalling the sworn jury after such a delay would present extremely difficult problems. Typically, at the commencement of a trial, the jury is advised of the estimated length of the trial. An interrupted trial would, of necessity, contravene any representations made as to how long jurors would have to be availáble. Furthermore, depending on the length of the recess necessary, when the trial finally resumed, it might be necessary either to reread the testimony of witnesses already sworn or actually to have them retestify. All of these problems, as well as others not detailed here, make respondent’s solution unworkable.
We are aware that, typically, attorneys know of and declare their conflicts of interest before trial. What occurred here will be infrequent. We conclude that when, during a trial, the attorney for a defendant discovers and declares a conflict of interest, and when the trial court concludes that conflict may prejudicially affect the defendant’s right to effective counsel, legal necessity requires a mistrial. The defendant’s consent to the mistrial under such circumstances is unnecessary.
Judgment is reversed and the information is ordered reinstated.
White, P. J., and Feinberg, J., concurred.
Respondent’s petition for a hearing by the Supreme Court was denied September 11, 1980.
Notes
Respondent did consent to the mistrial. However, he contends on appeal that he was never advised as to the effect of a mistrial, and that therefore his consent was ineffective. As we conclude his consent was unnecessary, we need not address this contention.
