Illinois v. Somerville

1973-02-27

Headline: Mistrial for defective indictment allowed retrial: Court upholds States’ power to retry defendants after a judge aborts trial for an insufficient indictment, ruling double jeopardy does not bar a new, valid indictment.

Holding: The Court ruled that when a judge aborts a trial because the indictment is legally insufficient, the mistrial met "manifest necessity," so the State may retry the defendant under a valid indictment without violating double jeopardy.

Real World Impact:

Allows states to retry defendants after judge-ordered mistrials for defective indictments.
Gives prosecutors a path to fix faulty indictments without automatic double jeopardy bar.
Strengthens trial judges’ discretion to stop unfair proceedings to protect public justice.

Summary

Background

A man in Illinois was charged with theft and a jury was sworn. The prosecutor realized the indictment failed to allege a required intent and the judge, believing the indictment could not be fixed under Illinois law, granted a mistrial over the defendant’s objection. A new grand jury returned a corrected indictment, the defendant was retried, convicted, and the conviction was later challenged on federal double jeopardy grounds.

Reasoning

The Court addressed whether aborting a trial for a defective indictment automatically prevents a later, proper trial. Relying on long-standing precedents about when judges may stop a trial, the majority concluded the mistrial met the old standard of “manifest necessity” because, under Illinois rules, the original indictment could not be amended and continuing would have wasted the public’s interest in obtaining a fair and lasting judgment. Therefore, the Double Jeopardy Clause did not bar the State from trying the defendant again under a valid indictment.

Real world impact

The ruling lets state courts correct certain fatal indictment defects without losing the chance to prosecute, when a judge reasonably finds the trial cannot fairly continue. It gives trial judges broader discretion in similar situations and signals that varied state procedural rules can justify a mistrial and retrial absent prosecutorial manipulation.

Dissents or concurrances

Several Justices dissented. They argued jeopardy attached when the jury was sworn and that prosecutorial error or oversight should not permit a second trial, stressing the defendant’s right to have the first jury decide his fate.
