There are five working mechanisms to abolish the death penalty in a U.S. jurisdiction: a legislature can repeal the capital sentencing statute, voters can pass a ballot initiative, a state supreme court can strike the penalty down under the state constitution, a governor can impose a moratorium, and a governor or the president can commute existing death sentences. Each route differs in what it actually changes, whether it reaches people already on death row, and how easily a future official can undo it. Knowing how to abolish the death penalty in practice means knowing which of these tools does what.
Legislative Repeal
The most common path runs through a state legislature. The process looks like any other law change: a repeal bill is introduced, debated in committee, voted on in both chambers, and sent to the governor for signature. The bill typically strikes the statutory language authorizing death as a sentence for capital-eligible offenses and replaces it with life in prison without parole. Once signed, prosecutors can no longer seek a death sentence in future cases.
The harder question is what a repeal does for people already sentenced to die. Most legislatures pass repeal bills that apply only going forward, leaving existing death sentences intact. This has happened repeatedly: states abolish the death penalty for future cases while the inmates already sentenced under the old law remain in their cells. Advocates often push for retroactive application, but legislators frequently lack the votes, and some state constitutions restrict retroactive changes to criminal law.
When repeal is only prospective, the people still on death row typically need separate relief through commutation, executive action, or further litigation. That disconnect can persist for years, producing the odd situation where a state has officially abandoned the death penalty but still houses inmates sentenced under it.
Ballot Initiatives
In states that allow ballot initiatives, voters can take the question directly into their own hands. Abolition measures have appeared on state ballots since the early 1900s, with mixed results. Some passed by razor-thin margins; more recent high-profile attempts have failed. The route is unpredictable because public opinion on capital punishment shifts with current events and with how the question is framed. A measure that fails in one cycle sometimes returns in modified form years later.
The ballot route has a political dimension that legislative repeal does not. Lawmakers can sometimes vote for abolition knowing their individual votes may go unnoticed, but a statewide referendum turns the issue into a public litmus test. Campaigns on both sides spend heavily, and outcomes often reflect the intensity of messaging as much as settled opinion. When a measure does pass, it carries the same legal force as a statute enacted by the legislature.
State Supreme Court Rulings
State supreme courts can abolish the death penalty by interpreting their own state constitutions, which often contain protections against cruel punishment similar to the Eighth Amendment but sometimes read more broadly. When a state court strikes down the death penalty on these grounds, the ruling does not depend on what the U.S. Supreme Court has said. It rests entirely on the state’s own constitutional protections, which means federal courts cannot override it.
Several state high courts have taken this path. Some found that the death penalty was applied in a racially discriminatory manner within their jurisdiction. Others found the state’s sentencing procedures constitutionally defective. Still others concluded that carrying out death sentences against inmates whose crimes were no longer statutorily eligible for the penalty amounted to disproportionate punishment under the state constitution.
The practical effect is often more immediate than legislative repeal. Existing death sentences in the jurisdiction are typically vacated, meaning current death row inmates receive new sentences. There is no gap between prospective and retroactive application because the court is declaring the entire system unconstitutional, not just changing the rules going forward. The downside for abolition advocates is that a future court could revisit the interpretation, and a constitutional amendment could override the ruling, though both are rare.
Gubernatorial Moratoriums
A governor can halt executions without waiting for the legislature or the courts. A moratorium is a formal directive suspending all executions for a defined or indefinite period. Governors typically ground this authority in their constitutional power to grant reprieves, which delays a sentence without erasing it. The conviction and the death sentence remain on the books; the state simply stops carrying them out.
Moratoriums are temporary by nature. One lasts only as long as the governor who issued it, or until a successor decides to continue it. A new governor can rescind the order on day one, and executions can resume under the existing sentences. Governors issue moratoriums for various reasons, from concerns about wrongful convictions to disputes over lethal injection drug protocols. Some use the pause to commission studies on the fairness of the state’s capital punishment system.
Because a moratorium does not change the law, it is the least permanent form of abolition. It is better understood as a stopgap that buys time for a more durable solution, whether that is legislative repeal, a court ruling, or commutation of individual sentences.
Commutation of Death Sentences
Commutation is the process of reducing a criminal sentence to something less severe. In the death penalty context, it means converting a death sentence into life in prison, typically without the possibility of parole. The governor holds this power for state convictions, and the president holds it for federal convictions. Some states route commutation requests through an advisory board that reviews individual cases and makes recommendations; others vest the decision solely in the governor.
Commutations can happen one case at a time or in bulk. There have been several instances of blanket clemency, where a governor or president commuted the sentences of all or nearly all death row inmates at once. The most recent large-scale federal commutation occurred in 2024, when the president commuted 37 of 40 federal death row sentences. Mass commutations tend to happen at the end of a term, and they are often controversial because they bypass the individual case review that normally accompanies clemency decisions.
Once a commutation is signed, it is legally final. The sentence cannot be reverted to death by a future governor or court. The former death row inmate is reclassified within the prison system and typically moved from a specialized death row unit into general maximum-security housing. The sentencing court updates its records to reflect the new sentence. This finality is what distinguishes commutation from a moratorium: a moratorium pauses the clock, while commutation permanently changes the sentence.
A note on scope: commutation ends the death sentence for the individuals it covers, but it does not repeal the underlying statute. Prosecutors in the same state can still seek death sentences in future cases unless one of the other mechanisms shuts that door.
The Federal Death Penalty Works Differently
Federal law authorizes the death penalty for certain offenses, including treason, espionage, and killings that meet specific intent thresholds under the Federal Death Penalty Act.1Office of the Law Revision Counsel. 18 USC 3591 – Sentence of Death The statute also covers large-scale drug trafficking operations that involve an intentional killing. No one under 18 at the time of the offense can be sentenced to death under federal law, consistent with the Supreme Court’s ruling in Roper v. Simmons.2Justia U.S. Supreme Court Center. Roper v Simmons, 543 US 551 (2005)
Abolishing the federal death penalty would require Congress to repeal the statute, because states cannot reach federal law. Short of that, executive action is the only lever. Federal execution policy has swung dramatically in recent years. A moratorium on federal executions was in place for nearly two decades before a series of executions resumed in 2020. A subsequent administration reinstated the moratorium, but in April 2026, the Department of Justice rescinded it and authorized seeking death sentences against dozens of defendants.3U.S. Department of Justice. The Justice Department Takes Actions to Strengthen the Federal Death Penalty Federal execution policy is heavily dependent on the priorities of the sitting administration and the Attorney General, which makes it far less stable than a statutory change.
What Happens to People Already on Death Row
This is the question that decides whether abolition is real for the people it most affects. The answer depends entirely on which mechanism the state used.
- A legislative repeal usually applies only prospectively. Existing death sentences remain in force unless the bill explicitly says otherwise.
- A ballot initiative works the same way as a statute; its effect on existing sentences depends on the text voters approved.
- A state supreme court ruling that strikes the death penalty down under the state constitution typically vacates existing death sentences, because the court is declaring the system itself invalid.
- A gubernatorial moratorium leaves every death sentence in place. It only pauses executions.
- Commutation changes the individual sentences it names and is permanent for those people, but it does nothing for anyone sentenced later.
Abolition advocates often pair mechanisms for this reason. A legislature can repeal the statute while the governor commutes the sentences of everyone currently on death row, closing both the forward-looking and backward-looking gaps at the same time.
How Permanent Is Abolition
Not every path is a one-way road, and the method determines how easily it can be undone. Legislative repeal is durable but reversible: a future legislature can pass a new death penalty statute if it has the votes and the governor’s signature. Judicial rulings based on state constitutions are harder to reverse because they require either a constitutional amendment or the court overruling its own precedent, but neither is impossible. Moratoriums can vanish with a change in administration.
Reinstatement is not theoretical. Several states abolished the death penalty in earlier eras only to bring it back years or decades later. The cycle is why abolition advocates often push for the most permanent mechanism available, whether that is a constitutional amendment, a broad judicial ruling, or a legislative repeal paired with commutations that make practical restoration difficult. A state that has commuted every death sentence and dismantled its execution infrastructure faces far higher barriers to reinstatement than one where a moratorium is the only thing standing between existing death warrants and the execution chamber.
