 The decision of life or death in the sentencing phase is serious which requires reliable sentencing.According to Justice Breyer, the court has “stressed the ‘acute need’ for reliable decision making when the death penalty is at issue.” Breyer stated that in Deck’s case his right to reliable sentencing was infringed upon (a right derived from the Eight Amendment).The Court then made it clear that the opinion of the Missouri Supreme Court did not meet the Constitutional requirements for permitting the shackling of Deck.
