People stay on death row for years because the legal system requires lengthy appeals to prevent executing innocent people.
Why
The Constitution requires due process. Capital cases get multiple appeals to avoid executing an innocent person.
Steps
Direct appeal, state post conviction, and federal habeas corpus review.
Average time
About 20 years between sentencing and execution in the US (Bureau of Justice Statistics shows average of around 20 years in recent years).
Facts
Since 1973, over 190 people on death row have been exonerated (Death Penalty Information Center).
Costs
Capital cases cost more.
Legal steps
Capital cases in the US go through trial, direct appeal to the state supreme court, state post-conviction review and federal habeas corpus review. Each stage can take years. Courts must ensure constitutional protections such as competent counsel and fair procedures, as required by the Eighth and Fourteenth Amendments.
- The Bureau of Justice Statistics reports the average time between sentencing and execution for those executed was about 20 years in recent years, with figures around 22 years in 2020.
- The Death Penalty Information Center records that more than 190 people on death row have been exonerated since 1973.
- Executions in the US have numbered in the dozens each year recently, 25 in 2024 and higher in 2025.
Costs and debate
Studies in several states, including California and Kansas, found capital cases cost more than non-capital cases because of longer trials and appeals. Supporters argue the process ensures accuracy, while critics argue delays are cruel and wasteful. Procedures differ by state, and 23 states had abolished the death penalty by 2023, with others under moratoriums.
Legal steps
Death row prisoners remain for years because of mandatory appeals: direct appeal, state post conviction and federal habeas corpus review. The average time from sentence to execution in the US was about 20 years in recent years, according to the Bureau of Justice Statistics. As of 2023, about 2,000 people were on death row.
Costs and debate
Studies show capital cases cost more than life sentences. Supporters cite justice and deterrence, while critics note risk of wrongful conviction. Since 1973 over 190 death row prisoners have been exonerated, according to the Death Penalty Information Center.
Appeals process
Capital cases include automatic direct appeal, state post conviction review and federal habeas petitions under the Antiterrorism and Effective Death Penalty Act of 1996, which limits successive petitions. The Supreme Court may review at each stage. Competency to be executed and method of execution challenges add time.
Numbers and costs
The average time between sentence and execution rose to about 20 years in recent decades. As of 2023, 27 states have the death penalty, with 24 executions in the US in 2023. The Death Penalty Information Center counts 195 exonerations since 1973. Studies in California and Maryland found each death penalty case costs millions more than life without parole cases.
