Ex post facto laws are prohibited by the US Constitution. The Constitution bans Congress and state governments from passing bills of attainder, which are laws that determine guilt and impose punishment without a trial. The Constitution also prohibits ex post facto laws, which are laws that retroactively create a crime where none existed before. While these two types of laws are distinct, they both protect against legislative overreach and preserve the separation of powers. The prohibitions against ex post facto laws were informed by Founding Era history and abuses of ex post facto laws, such as those committed by state legislatures. The prohibitions are also closely related to the constitutional ban on bills of attainder.

What You'll Learn
The Ex Post Facto Clause and its prohibition
The Ex Post Facto Clause is a part of the US Constitution's Article I, Section 9, Clause 3, which states that "no Bill of Attainder or ex post facto Law shall be passed". The Ex Post Facto Clause prohibits the federal and state governments from enacting laws that impose criminal liability or increase criminal punishment retroactively. In other words, it prevents the government from passing laws that make an act criminal after the act has already been committed or from increasing the punishment for a crime after it has been committed.
The clause is designed to protect against legislative overreach and preserve the separation of powers. It ensures that individuals are given fair warning of the consequences of their actions and that the government's power to enact criminal laws is restrained. The Ex Post Facto Clause also reinforces the idea that the government cannot punish someone without due process, which typically includes a trial.
The Supreme Court has provided guidance on the interpretation of the Ex Post Facto Clause. For example, in Calder v. Bull, Justice Chase described four categories of ex post facto laws, two of which related to punishment. One category was laws that inflict punishment where no punishment was previously authorised, and the other was laws that increase the punishment beyond what was authorised when the crime occurred. The Court has also held that a law is not considered ex post facto if it does not disadvantage criminal defendants, even if it imposes a retroactive criminal punishment.
The Ex Post Facto Clause has been the subject of debate and interpretation by the Supreme Court and legal scholars. Some argue that the clause was originally understood to encompass both criminal and civil laws, while others contend that it was limited to criminal laws. There are two Ex Post Facto Clauses in the Constitution, one applying to federal laws and the other to state laws, but only one clause can be applied to a given piece of legislation.
In conclusion, the Ex Post Facto Clause is an important part of the US Constitution that prohibits the enactment of laws with retroactive criminal effect. It serves to protect individuals from arbitrary and oppressive legislative actions and ensures that the government's power to punish is constrained by due process and fair warning.

The historical context of the Ex Post Facto Clause
The Ex Post Facto Clause, or the prohibition on ex post facto laws, is a fundamental principle enshrined in the United States Constitution. This clause, found in Article I, Section 9, Clause 3, states unequivocally that "no Bill of Attainder or ex post facto Law shall be passed." This clause serves as a critical safeguard against legislative overreach and reinforces the separation of powers by prohibiting the federal and state governments from enacting certain types of laws.
The concept of ex post facto laws has a long history in common law and civil law traditions. The Latin phrase "ex post facto" translates to "from something done afterward," indicating that these laws have retrospective effects. The Founding Fathers were influenced by Enlightenment ideals of fairness, justice, and the rule of law, which informed their decision to include this protection in the Constitution.
The Ex Post Facto Clause has been interpreted and refined through a series of court cases over the years. One notable case is Calder v. Bull (1798), where Justice Chase provided an alternative description of ex post facto laws, identifying four categories, two of which related to punishment. These categories included laws that inflicted punishment where none was previously prescribed and laws that increased the severity of punishment beyond what was authorized when the crime was committed.
The clause has been invoked in various contexts, such as in the case of Lindsey v. Washington (1937) and Weaver v. Graham (1981), where the Supreme Court denied ex post facto claims, and in the context of deportation laws for members of the Communist Party in the 1920s. The interpretation and application of the Ex Post Facto Clause continue to evolve through judicial decisions, shaping the understanding of this crucial constitutional protection.

The Supreme Court's interpretation of the Ex Post Facto Clause
The United States Constitution prohibits ex post facto laws in Article 1, Section 9, Clause 3 (federal laws) and Article 1, Section 10 (state laws). The Ex Post Facto Clause prevents the federal and state governments from enacting laws that impose criminal liability or increase criminal punishment retroactively.
The Supreme Court has interpreted the Ex Post Facto Clause to mean that laws cannot be applied retroactively to impose or increase criminal punishment. In the case of Starkey v. Oklahoma Department of Corrections, the Supreme Court of Oklahoma found that the Oklahoma Sex Offender Registration Act (SORA) was punitive in nature, even if that was not the intention. The Court held that the Department's retroactive application of the law violated the Ex Post Facto Clause.
The Supreme Court has also held that the Ex Post Facto Clause does not prohibit the application of lower penalties or the mitigation of the rigor of the law in force at the time the crime was committed. For example, in California Dep't of Corrections v. Morales, the Supreme Court applied the standard from Beazell v. Ohio, which defined the scope of the constitutional ex post facto clause. The Court held that an amendment that impacts someone currently imprisoned does not violate the Ex Post Facto Clause if it does not increase the punishment attached to the respondent's crime.
The Court has also denied ex post facto claims when it found that a law is not ex post facto as applied to the challenger, even if it might be for others not before the Court. For instance, in Jaehne v. New York, the challenger argued that a law was invalid because it could be ex post facto in some cases, but the Court denied the claim because the law was not ex post facto as applied to the challenger.
The Supreme Court has also held that the constitutional prohibitions on ex post facto laws do not apply to crimes committed outside the jurisdiction of the United States against the laws of a foreign country. In Neely v. Henkel, the Court held that the Ex Post Facto Clause did not apply to a U.S. citizen who committed a crime in a foreign country, even if the law was retroactive.
The Ex Post Facto Clause is closely related to the prohibition on bills of attainder, which are legislative actions that determine guilt or impose criminal punishment on specific persons or groups without a judicial trial. In Cummings v. Missouri, the Court struck down a federal law as a bill of attainder and an ex post facto law because it targeted and punished a specific group without a trial, and criminally punished people for actions that were not criminal when they took them.

The relationship between Ex Post Facto and Bill of Attainder
Ex Post Facto and Bills of Attainder are two types of prohibited laws that are closely related but legally distinct. The US Constitution prohibits Congress from issuing such laws.
Ex Post Facto laws are those that impose criminal liability or increase criminal punishment retroactively. In other words, these laws retroactively create a crime where none existed before. For example, in the case of United States v. Lovett (1946), the Supreme Court struck down a law as an ex post facto law because it criminally punished people for actions that were not criminal when they were committed.
Bills of Attainder, on the other hand, are laws that determine guilt or impose criminal punishment on specific persons or groups without a judicial trial. For instance, in the same Lovett case, the Court also struck down the law as a bill of attainder because it targeted a specific group of people and punished them without a trial.
Both types of laws are prohibited by the US Constitution to protect against legislative overreach and preserve the separation of powers. The prohibition against Bills of Attainder reinforces the idea that the government cannot punish someone unless they receive due process, which usually means a trial. Similarly, the prohibition against Ex Post Facto laws reinforces the notion that the government cannot punish someone retroactively for an action that was lawful at the time.
While these two types of laws are distinct, they are often related and can overlap. For example, in the Lovett case, the law was struck down as both a bill of attainder and an ex post facto law because it targeted a specific group and punished them for actions that were not criminal when they were taken without a trial.
In summary, Ex Post Facto and Bills of Attainder are prohibited types of laws that are distinct but often related. They are prohibited by the US Constitution to protect citizens against legislative overreach and ensure due process and the separation of powers.

The application of the Ex Post Facto Clause to federal and state laws
The Ex Post Facto Clause of the United States Constitution, found in Article 1, Section 9, Clause 3, prohibits the federal government from enacting laws that impose criminal liability or increase criminal punishment retroactively. This means that Congress cannot pass laws that make an action criminal after it has been committed or increase the punishment for a crime after it has been committed. The Supreme Court has interpreted this clause to apply only to criminal matters and not civil matters, and it has established four categories of unconstitutional ex post facto laws:
- Making criminal an action taken before enactment that was lawful when done
- Increasing the severity of an offense after it was committed
- Increasing the punishment for a crime after it was committed
- Altering the rules of evidence after an offense to make it easier to convict
The Ex Post Facto Clause also applies to the states through Article 1, Section 10, Clause 1, which prohibits state governments from enacting ex post facto laws. While there are two Ex Post Facto Clauses, only one can apply to any given piece of legislation. The Supreme Court has cited cases interpreting the federal clause in challenges under the state clause and vice versa, implying that the two clauses have the same scope.
The prohibition on ex post facto laws is closely related to the prohibition on bills of attainder, which are legislative actions that determine guilt or impose criminal punishment on specific persons or groups without a judicial trial. Both types of laws are prohibited by the Constitution to protect against legislative overreach and preserve the separation of powers.
The Supreme Court has held that the constitutional prohibitions on ex post facto laws do not apply to crimes committed outside the jurisdiction of the United States against the laws of a foreign country. Additionally, the Court has denied ex post facto claims when it found that a law was not ex post facto as applied to the challenger, even if it might be for others not before the Court. In some cases, a law may impose retroactive punishment but still be constitutional if the person was "adequately forewarned" about the prohibited nature and consequences of their actions when they committed them.
