Mabry v. Johnson

Background

In 1970, a family’s home was invaded, shots were fired, and a daughter was killed; one of the burglars was wounded and later convicted of burglary, assault, and murder. The state court set aside the murder conviction, and while the defendant was serving concurrent prison terms he and prosecutors negotiated plea deals. A prosecutor first offered a recommended 21-year sentence to run concurrently; the defendant accepted but the prosecutor withdrew that offer and instead proposed a consecutive 21-year recommendation. The defendant rejected the change, went to trial, then later pleaded guilty under the second offer and received the consecutive sentence. He then sought federal habeas relief claiming the earlier accepted offer should have been enforced.

Reasoning

The Court addressed whether merely accepting a prosecutor’s proposed plea creates a constitutional right to force that bargain. It held that a plea agreement by itself is an executory promise and does not by itself trigger constitutional protection; only an actual guilty plea can implicate constitutional rights like due process. The Court relied on established rules that a guilty plea must be voluntary and made with competent counsel. Because the defendant pleaded guilty knowing the prosecutor would recommend a consecutive sentence and with competent advice, his plea was voluntary and not based on an unfulfilled promise. The prosecutor’s mistaken withdrawal or negligence did not make the plea constitutionally invalid, and claims about counsel’s performance were rejected on the record.

Real world impact

The decision means defendants generally cannot use federal habeas law to force prosecutors to honor pre-plea offers that were withdrawn before a plea. Prosecutors may change offers before a guilty plea, and courts will focus on whether any final plea was made voluntarily and with effective counsel. The ruling leaves open that if a plea was actually induced by a broken promise, different remedies may be available.
