Ex post facto laws are those that retroactively criminalize actions that were legal when they were committed. The United States Constitution, in Article 1, Sections 9 and 10, prohibits Congress and state governments from enacting such laws. The Supreme Court has held that people must have notice of the possible criminal penalties for their actions at the time of the act. However, the prohibition on ex post facto laws does not apply to judicial decisions or to civil laws that adversely affect private rights. While some countries with a Westminster system of government may allow ex post facto laws due to parliamentary supremacy, others, like France, explicitly prohibit them in their constitutions.

Ex post facto laws in the US Constitution
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). These laws are considered to be contrary to the first principles of the social compact and to every principle of sound legislation.
In a legal context, ex post facto laws refer to criminal statutes that punish actions retroactively, thereby criminalizing conduct that was legal when originally performed. In other words, they retroactively change the legal consequences or status of actions that were committed or relationships that existed before the enactment of the law.
The United States Constitution prohibits both Congress and state governments from passing ex post facto laws. The Supreme Court has held that ex post facto laws apply only to legislative decisions and not to judicial decisions. The Court has also ruled that an amendment impacting someone currently imprisoned does not violate ex post facto laws if it does not increase the punishment attached to the crime.
Despite the prohibition on ex post facto laws, the United States Supreme Court has, over the years, referred to its ruling in Calder v. Bull, which established four categories of unconstitutional ex post facto laws and held that the prohibition applied only to criminal matters, not civil matters. As a result of this ruling, several retroactive taxes have been passed by the US Congress, starting with the 1913 Revenue Act.

Ex post facto laws in other nations
Ex post facto laws are a feature of legal systems in several countries. In the United States, two clauses in the Constitution prohibit ex post facto laws, one applying to Congress and the other to the states. The Supreme Court has held that "people must have notice of the possible criminal penalties for their actions at the time of the act". In administrative law, federal agencies may apply their rules retroactively if authorised by Congress; otherwise, retroactive application is generally prohibited.
In the United Kingdom, ex post facto laws are permitted by virtue of the doctrine of parliamentary sovereignty. All acts of Parliament before 1793 were ex post facto legislation, as their date of effect was the first day of the session in which they were passed. This was rectified by the Acts of Parliament (Commencement) Act 1793.
Article 9.3 of the Spanish Constitution prohibits ex post facto criminal laws or any other retroactive punitive provisions. The European Court of Human Rights ruled in 2013 that the Parot doctrine, in which terrorists were denied the right to earn a reduction in the length of their sentences, was contrary to relevant articles on retroactivity and liberty and security.
Article 58 of the Constitution of Ukraine states that laws and other regulatory acts shall have no retroactive force except where they mitigate or nullify the responsibility of a person.
Article 103 of the German Basic Law requires that an act may be punished only if it was already punishable by law at the time it was committed.

Ex post facto laws in relation to bills of attainder
Ex post facto laws and bills of attainder are closely related concepts that are often mentioned together in the US Constitution, which prohibits both. Ex post facto laws are expressly forbidden by the US 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 also bans bills of attainder in federal law under Article 1, Section 9, Clause 3, and in state law under Article 1, Section 10.
Ex post facto laws are laws that retroactively create a crime where none existed before, or laws that retroactively impose criminal liability or punishment for actions that were legal at the time. In other words, ex post facto laws punish people for an action that was not a crime when they performed it. For example, legislation criminalising certain war crimes retrospectively has been held to be constitutional.
Bills of attainder, on the other hand, are laws that legislatively determine guilt and inflict punishment upon an identifiable individual or group without providing the protections of a judicial trial. They are called "bills of pains and penalties" if they inflict a milder degree of punishment than death. In English common law, bills of attainder referred only to laws that imposed the death penalty on specific people. Bills of attainder are considered to violate the separation of powers by allowing the legislature to perform judicial or executive functions. They also embody the concept of due process, reinforced by the Fifth Amendment to the Constitution.
While bills of attainder and ex post facto laws are similar, they are legally distinct. The US Supreme Court has overturned laws that violated both clauses. For example, in United States v. Brown, the Supreme Court held void a statute that made it a crime for a member of the Communist Party to serve as an officer or employee of a labor union. In another case, the Supreme Court held that an amendment that impacts someone currently imprisoned does not violate ex post facto laws if it does not increase the punishment attached to the respondent's crime.

Ex post facto laws in criminal law
Ex post facto laws, in the context of criminal law, refer to the retroactive application of criminal statutes. In other words, it involves the criminalisation of actions that were previously legal or the imposition of harsher penalties for crimes that have already been committed. This concept is rooted in the principle of fairness, aiming to ensure that individuals are aware of the legal consequences of their actions and can rely on the stability of the law.
The United States Constitution expressly forbids ex post facto laws at both the federal and state levels. Article 1, Section 9, Clause 3, and Article 1, Section 10, respectively, prohibit Congress and the states from enacting such laws. This prohibition extends to legislative decisions, as established in Rogers v. Tennessee (2000) and City of Columbia (1964). The Supreme Court has clarified that retroactive criminal statutes that do not disadvantage criminal defendants are not considered ex post facto laws.
However, the interpretation and application of ex post facto laws vary across different jurisdictions. For instance, Australia does not have a strong constitutional prohibition against these laws, although narrowly retrospective laws may violate the constitutional separation of powers principle. Similarly, while Canada prohibits ex post facto criminal laws under its Charter of Rights and Freedoms, changes to civil law can still be enacted retrospectively.
Historically, there have been exceptional cases where ex post facto criminal laws were employed. For example, Finland passed such laws after World War II to prosecute political leaders for their involvement in the war and to address instances of military personnel preparing for guerrilla resistance. These laws resulted in convictions and executions, highlighting the controversial nature of ex post facto legislation.
It's important to note that the prohibition of ex post facto laws is not absolute. In some instances, retroactive laws can benefit the accused, as seen in France and Brazil, where retroactive criminal laws that are more favourable to the accused may be applied. Additionally, amnesty laws, a form of ex post facto legislation, can decriminalise certain acts or prohibit prosecution, serving as a tool to provide amnesty for specific offences.

Ex post facto laws in civil law
Ex post facto laws are expressly forbidden by the US Constitution, which states that no ex post facto law shall be passed. The US Supreme Court has interpreted this prohibition to apply only to laws that are criminal or penal in nature, and not to civil laws.
In the 1798 case of Calder v. Bull, the Supreme Court set out four categories of ex post facto laws, two of which related to punishment. The first category is laws that inflict punishment where no punishment was liable before the law was passed. The second is laws that inflict a greater punishment than was authorised when the crime was committed.
The prohibition against ex post facto laws relates only to penal and criminal legislation, and not to civil laws that adversely affect private rights. For example, in Smith v. Doe, the US Supreme Court upheld the application of Alaska's Megan's Law to sex offenders who were convicted before the law's enactment. The law requires released sex offenders to register with local police and provides for public notification via the internet. The Court determined that the legislative intent was civil and non-punitive, promoting public safety by protecting the public from sex offenders.
In some countries that follow the Westminster system of government, ex post facto laws may be possible due to the doctrine of parliamentary supremacy. For example, Article 29 of the Constitution of Albania explicitly allows retroactive effect for laws that alleviate possible punishments. In Canada, changes to civil law can be, and occasionally are, enacted ex post facto. For instance, a convicted murderer was ordered to forfeit proceeds from a book published after his parole under a law passed after his conviction. The courts ruled that the law prescribed only civil penalties and was therefore not subject to Charter restrictions.
In Australia, there is no strong constitutional prohibition on ex post facto laws, although narrowly retrospective laws may violate the constitutional separation of powers principle. Australian courts generally interpret statutes with a strong presumption against retrospectivity. However, retrospective laws have been passed in certain cases, such as prosecuting unethical tax avoidance or criminalising certain war crimes retrospectively.
