*905 OPINION
Lester Gamble appeals from the district court’s denial of his petition for post-conviction relief, in which he sought to withdraw his plea of guilty to a charge of attempted grand larceny *906 or, in the alternative, to obtain specific enforcement of his plea bargain. We reverse the judgment of the district court and remand for further proceedings.
In December, 1977, appellant Gamble was arraigned on a charge of grand larceny and entered a plea of not guilty. As a result of negotiations with the prosecutor, a plea agreement was reached: Gamble, who was then on probation for a previous conviction, agreed to stipulate to the revocation of probation and to plead guilty to the present grand larceny charge; the prosecution promised not to file an unrelated grand larceny charge against appellant and to agree to the imposition of concurrent sentences on the present grand larceny charge and on the probation revocation. After a proper canvass by the district judge, which included the fact that the plea was being entered pursuant to plea negotiations and that the prosecutor was agreeing to the imposition of a concurrent sentence, the plea of guilty was accepted and entered on February 17, 1978. While in custody after the entry of the plea, appellant was hospitalized with an ailment whose nature is not disclosed by the record.
On March 15, 1978, a hearing was held in Department 8 of the Eighth Judicial District Court to revoke appellant’s probation. Appellant was represented by a different public defender than the one representing him in the instant case, and the State was represented by a different deputy district attorney. No reference was made to the plea negotiations in the instant case, and no attempt was made to have appellant stipulate to the revocation of probation. After the hearing, probation was revoked and appellant was sentenced to a ten year prison term.
On March 28, 1978, a sentencing hearing was held in Department 7 of the Eighth Judicial District Court on the charge at issue in the instant case. It appeared then that the appellant had not stipulated to the revocation, but it was the first either defense counsel or the prosecutor had heard of the probation revocation hearing. As the deputy district attorney put it, “I just don’t have any explanation for what’s happened.” That hearing was continued.
The final sentencing hearing occurred on April 11, 1978. At this hearing, the deputy district attorney represented that appellant had “refused” to stipulate to the revocation of his probation, and recommended that the maximum sentence on the present grand larceny charge be imposed to run consecutively to the sentence imposed as a result of the probation revocation. The appellant then stated that, if the sentence was not to be imposed as agreed in the plea negotiations, he wished to withdraw his plea of guilty. Appellant’s counsel argued that the *907 plea bargain had been broken through no fault of appellant but rather through inadequate communication within the district attorney’s office and between that office and defense counsel. The district judge imposed a five year sentence, to run consecutively to that on the probation revocation. Gamble sought post-conviction relief in the district court, contending that the prosecution had not kept its promises in the plea bargain, that his guilty plea was therefore involuntary, and that, as a result, he should be permitted to withdraw the plea. The district court denied his petition after a hearing which consisted of argument of counsel and consideration of the points and authorities submitted; and this appeal followed.
We find that the hearing held by the district court was insufficient to establish the appellant’s alleged breach of the plea bargain. When more than a bare allegation is made that a guilty plea was induced by promises made by the prosecution, Vaillancourt v. Warden,
The reason for this rule is the requirement of fairness in plea negotiations recognized in Santobello v. New York,
It is equally clear that the fact of a breach of a plea bargain must be determined by the court: “to set aside a judicially approved plea bargain, the prosecution may not act unilaterally but ... on
adequate evidence,
a judge must find that there has been a substantial breach of the bargain which the court had approved.” United States v. Simmons,
The district court’s evidentiary determination of whether the breach of the plea bargain was caused by the appellant’s desire to repudiate it or by the prosecution’s not letting “the right hand know what the left hand is doing,” Santobello v. New York,
The order of the district court is reversed and the cause remanded for further proceedings consistent with this opinion.
