The US Constitution bans both the federal government and state governments from enacting such laws. Article 1, Section 9, Clause 3 of the US Constitution states that no Bill of Attainder or ex post facto Law shall be passed. This clause prohibits Congress from passing any laws that apply ex post facto. Article 1, Section 10 of the US Constitution contains a similar prohibition for state governments.

What You'll Learn
The US Constitution prohibits ex post facto laws
The US Constitution expressly forbids ex post facto laws in Article 1, Section 9, Clause 3 (with respect to federal laws) and Article 1, Section 10 (with respect to state laws). These constitutional provisions ensure the separation of powers and prevent legislative overreach.
The prohibition against ex post facto laws is closely related to the prohibition of bills of attainder, which are legislative actions that determine guilt or impose criminal punishment on specific persons or groups without a judicial trial. The US Constitution prohibits Congress from issuing bills of attainder, reinforcing the idea that the government cannot punish someone unless they receive due process, typically in the form of a trial.
The Supreme Court has provided clarity on the scope of ex post facto laws, stating that any statute that punishes an act that was previously innocent, increases the punishment for a crime after its commission, or deprives a defendant of a defence that was available at the time of the act is prohibited as ex post facto.
The prohibition on ex post facto laws seeks to assure that legislative acts give fair warning of their effects and permit individuals to rely on their meaning until explicitly changed. It also restricts governmental power by restraining arbitrary and potentially vindictive legislation.

Ex post facto laws and bills of attainder are distinct
An ex post facto law is one that retroactively creates a crime where none existed before. It imposes criminal liability or increases criminal punishment after the fact, for actions that were legal at the time they were committed. The term "ex post facto" is Latin for "after the fact".
A bill of attainder, on the other hand, is a law that determines guilt and inflicts punishment on a specific person or group without a judicial trial. Bills of attainder are often aimed at specific classes of people, such as those accused of treason or felony, and are passed without the usual judicial proceedings.
While both concepts involve legislative action and the punishment of individuals, the key distinction lies in the presence or absence of a trial. Ex post facto laws are passed without a trial, whereas bills of attainder are passed in addition to a trial, imposing further punishment on those already convicted.
In the US, the Constitution prohibits Congress from issuing bills of attainder, reinforcing the idea that the government cannot punish someone without due process. The prohibition against ex post facto laws, meanwhile, ensures that people have notice of potential criminal penalties before taking actions that could be deemed illegal.

Ex post facto laws in other nations
Ex post facto laws are prohibited by the constitutions of several nations, including Spain, South Africa, Germany, and the United States.
Article 9.3 of the Spanish Constitution guarantees the principle of non-retroactivity of punitive provisions that are not favourable to or restrictive of individual rights. The European Court of Human Rights has ruled that the Parot doctrine, which denied terrorists the right to earn a reduction in their sentences, was contrary to relevant articles on retroactivity, liberty, and security.
Section 35(3) of the South African Bill of Rights prohibits ex post facto criminal laws, except for acts that violated international law at the time they were committed, even if they were not illegal under national law.
Article 103 of the German Basic Law states that an act may only be punished if it was already punishable by law, specifically written law, at the time it was committed.
The United States Constitution contains two Ex Post Facto Clauses, prohibiting both the federal government and the states from passing ex post facto laws. These clauses are closely related to the prohibitions of bills of attainder, which impose criminal punishment on specific persons or groups without a judicial trial. The Supreme 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. The Court has also held that these prohibitions do not apply to crimes committed outside the jurisdiction of the United States against the laws of a foreign country.
In the United Kingdom, ex post facto laws are permitted by the doctrine of parliamentary sovereignty. However, the Acts of Parliament (Commencement) Act 1793 rectified this situation, and now laws are typically passed prospectively.
In Ukraine, Article 58 of the Constitution states that laws and other regulatory acts shall have no retroactive force except where they mitigate or nullify the responsibility of a person.
While not a nation, the European Court of Human Rights has also ruled on ex post facto laws in the context of the épuration légale trials in France after World War II. The Court ruled that the introduction of the status of indignité nationale for Nazi collaborators did not violate ex post facto principles.

The historical background of ex post facto laws
Ex post facto laws are expressly forbidden by the United States Constitution in Article 1, Section 9, Clause 3 (with respect to federal laws) and Article 1, Section 10 (with respect to state laws). The Constitution's Ex Post Facto Clause prohibits applying a new Act's higher penalties to pre-Act conduct, but does not prohibit applying lower penalties.
James Madison, in Federalist No. 44, asserted that ex post facto laws were "contrary to the first principles of the social compact, and to every principle of sound legislation." He further noted that several state constitutions had already banned ex post facto laws, and that such laws were prohibited by the spirit and scope of these charters.
Despite this disapproval, some delegates argued that an explicit prohibition was unnecessary because ex post facto laws were clearly invalid. One delegate contended that there was no lawyer or civilian who would not say that ex post facto laws were void. There was also a discussion about whether the prohibition on ex post facto laws applied only to retroactive criminal laws or if it also included retroactive civil laws. The delegates rejected a suggestion to alter the federal Ex Post Facto Clause to expressly include civil laws, leaving the question unresolved.
The Supreme Court has played a significant role in interpreting and applying the constitutional prohibition on ex post facto laws. In Calder v. Bull (1798), the Court construed the prohibition to apply only to retroactive criminal laws. Similarly, in Beazell v. Ohio (1925), the Court held that retroactive criminal statutes that do not disadvantage criminal defendants are not ex post facto laws.
In summary, the historical background of ex post facto laws in the United States involves debates among the Founding Fathers, the influence of state constitutions, and key Supreme Court interpretations that have shaped the understanding and application of these laws over time.

Ex post facto laws and the Supreme Court
The United States Constitution expressly forbids 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 prohibits applying a new Act's higher penalties to pre-Act conduct, but it does not prohibit applying lower penalties. The Supreme 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. For example, in Jaehne (1888), the challenger argued that a law was invalid because it could be ex post facto in some cases, but the Court denied the claim.
The Supreme Court has also held that 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. For instance, in Neely v. Henkel (1901), the Court rejected an ex post facto claim regarding a crime committed outside US jurisdiction.
The Supreme Court has cited cases interpreting the federal Ex Post Facto Clause in challenges under the state clause and vice versa, implying that the two clauses have the same scope. For example, in Peugh v. United States (2013), the Court construed the federal clause by citing a case that construed the state clause. The Court has also overturned laws for violating both the ex post facto clause and the bill of attainder clause, which prohibits legislative actions that determine guilt or impose criminal punishment without a judicial trial. For example, in Cummings v. Missouri (1866), the Court overturned a law that violated both clauses.
In Dobbert v. Florida, the Supreme Court may have formulated a new test for determining when the punishment provided by a criminal statute is ex post facto. In this case, the defendant murdered two of his children when Florida law provided the death penalty for such offences. The Supreme Court held capital sentencing laws similar to Florida's unconstitutional, but the Florida Supreme Court then enacted a new capital punishment law, which was sustained. Dobbert was convicted and sentenced to death under the new law, and the Supreme Court rejected the ex post facto challenge to the sentence.
