Whether the prosecution's breach of a promise to make no sentencing recommendation, made as part of a guilty-plea agreement, requires relief even though the sentencing judge said he was not influenced by the improper recommendation.
Holding
Yes. When a guilty plea rests in a significant degree on a prosecutor's promise, that promise must be fulfilled; the prosecutor's breach required that the judgment be vacated and the case remanded for an appropriate remedy.
Reasoning
Plea bargaining is an essential and often beneficial part of criminal justice because it permits prompt resolution of charges and avoids the burdens of trying every case. But its legitimacy depends on fairness in the negotiations that induce a defendant to waive the fundamental rights surrendered by a guilty plea.
A guilty plea must be voluntary and knowing. When a prosecutor's promise forms a significant part of the inducement or consideration for the plea, fulfillment of that promise is necessary to ensure that the plea rests on a fair and reliable basis.
Santobello pleaded guilty not only to obtain dismissal of more serious charges but also on the express condition that the prosecutor would make no sentencing recommendation. The State conceded that the promise had been made, yet the successor prosecutor affirmatively recommended the maximum sentence.
The breach was not excused by the successor prosecutor's ignorance of the agreement. A prosecutor's office must ensure that its lawyers know and honor commitments made by colleagues; an inadvertent breach still deprives the defendant of the promised benefit of the bargain.
The Court did not need to determine whether the sentencing judge was actually influenced by the prosecutor's recommendation. Although the judge stated that he relied instead on the presentence report and the defendant's criminal history, the State's duty to honor its own plea commitments exists independently of proof that the breach affected the sentence.
