Santobello v. New York

Santobello (defendant) pleaded guilty to a lesser offense after the prosecutor promised to make no sentencing recommendation to the judge. At sentencing, a different prosecutor from the same office, apparently unaware of that promise, recommended the maximum one-year sentence; despite defense counsel's objection, the sentencing judge imposed the maximum sentence, stating he was not influenced by the recommendation and that Santobello's criminal history justified it anyway.
