What this case is about

Carman Deck argues that visible shackles during sentencing violate his due process rights. The State of Missouri argues that trial courts hold broad discretion to order security measures. The core conflict involves the allocation of the burden of proof for justifying restraints.

How the case got here

The Supreme Court heard oral argument in this case on March 1, 2005.

What each side wants

Deck wants the Court to rule that the state must prove a specific security threat before using visible restraints.

Missouri wants the Court to affirm that trial courts possess broad discretion to order security measures without a specific evidentiary burden.

What each side says

Deck contends that shackling during sentencing violates the Sixth, Eighth, and Fourteenth Amendments by undermining the reliability of the proceeding.

Missouri contends that the trial court needs discretion to fashion security measures, particularly in penalty phase cases, to ensure safety.

What the justices asked

Justice Kennedy asked if the state bears the burden of proof when compromising a defendant's right not to be shackled.

Justice Souter asked for the basic justification for shackling and whether insufficient bailiffs caused the measure during trial itself.

Why it matters

This case defines the constitutional limits on visible restraints during criminal sentencing. It determines whether defendants retain a right to appear unshackled unless the state proves a specific threat. The outcome shapes the balance between courtroom security and the integrity of the judicial process.
