A constitutional standard for determining whether a punishment violates the Eighth Amendment prohibition on cruel and unusual punishments. The standard requires courts to assess contemporary values reflected in legislation and other objective indicia rather than fixed historical notions of acceptable punishment.
Blake directed ultra-bright floodlights from his store roof straight into Sonia's bedroom windows after she opposed his liquor license. Sonia suffered repeated sleep loss and sued for private nuisance. The court found the invasion unreasonable because the configuration was spiteful and offended common standards of decency.
A state convicted an adult of murder and sought capital punishment. The defendant argued the sentence had become unacceptable under current norms. The court upheld the penalty after confirming that a majority of states still authorized death for the crime and juries continued to impose it.

A state sentenced a mentally retarded adult to death for murder. The defendant challenged the sentence on Eighth Amendment grounds. The court barred the execution because a growing number of states had enacted laws prohibiting capital punishment for such offenders, reflecting changed societal values.
A defendant facing death presented statistical evidence of racial bias in sentencing decisions. The court rejected the claim because the data did not prove purposeful discrimination in his specific case and states continued to authorize capital punishment without categorical rejection of the practice.
A state imposed a mandatory life-without-parole sentence on a juvenile convicted of murder. The defendant challenged the sentence as disproportionate. The court struck the mandatory term because national consensus and scientific evidence on adolescent development showed juveniles are less culpable than adults.
A state scheduled execution of a prisoner who had become insane after conviction. The prisoner sought a stay on Eighth Amendment grounds. The court halted the execution because contemporary standards prohibit carrying out a death sentence on a person who cannot comprehend the punishment or its reason.
Courts look first to objective indicia such as legislation enacted by state legislatures and the frequency of jury imposition of a challenged punishment. These sources provide the clearest evidence of contemporary values without requiring subjective judicial judgment.

Yes. Because the standard is not static, a punishment previously permitted may become cruel and unusual if legislation and practice show that society has rejected it. Atkins v. Virginia illustrates this shift regarding execution of the mentally retarded.

International practices may supply confirmatory evidence of evolving standards but are not controlling. Courts primarily rely on domestic legislation and jury behavior to determine whether a punishment remains acceptable in the United States.
