Ex post facto laws are laws that retroactively change the legal consequences of actions committed or relationships that existed before the law was enacted. In criminal law, this can mean criminalizing actions that were legal when committed, aggravating a crime by bringing it into a more severe category, altering the rules of evidence to make conviction more likely, or changing the punishment prescribed for a crime. While ex post facto laws are prohibited in the US Constitution and many other countries, they can be used in certain circumstances, such as when new evidence emerges or to prevent abuses of government power. For example, the Criminal Justice Act 2003 in the UK allows for the retrial of individuals acquitted of murder if new, compelling, reliable, and substantial evidence emerges.

Criminalising past innocent actions
Ex post facto laws are those that retroactively change the legal consequences of actions that were committed before the law was enacted. In criminal law, this can mean criminalising actions that were legal when committed.
In the United States, ex post facto laws are prohibited by the Constitution in criminal cases. The federal constitution interdicts them in criminal cases, and Thomas Jefferson argued that they are equally unjust in civil cases. The US Supreme Court has defined the scope of the constitutional ex post facto through the following restrictions:
> It is settled, by decisions of this Court so well known that their citation may be dispensed with, that any statute which punishes as a crime an act previously committed, which was innocent when done, which makes more burdensome the punishment for a crime, after its commission, or which deprives one charged with a crime of any defence available according to law at the time when the act was committed, is prohibited as ex post facto.
Despite this, there are some examples of ex post facto laws being used in the US. In California Dep't of Corrections v. Morales, a law was amended to state that the California Board of Prison Terms may defer parole hearings for up to three years for prisoners convicted of more than one homicide offence. The Supreme Court found that this was not an ex post facto law as it was a "routine exercise of common law decision-making that brought the law into conformity with reason and common sense".
In the UK, the Criminal Justice Act 2003 allows people acquitted of murder and certain other serious offences to be retried if there is "new, compelling, reliable and substantial evidence" that they were guilty. This Act applies retroactively and has been used to reprosecute people who were acquitted before it came into force.
In some countries, there is no constitutional prohibition on ex post facto laws. For example, Lithuania has no such prohibition. In international criminal law, the Nuremberg trials prosecuted war crimes and crimes against humanity perpetrated in World War II, despite the procedural law under which the trials were held postdating VE Day. The tribunal rejected the defence that the criminal law was ex post facto, arguing that it derived from earlier treaties.

Retroactively decriminalising certain acts
Ex post facto laws are laws that retroactively alter the legal consequences of actions committed before the law's enactment. While ex post facto laws are prohibited by the US Constitution, they can be used to retroactively decriminalise certain acts.
Retroactive decriminalisation involves removing criminal penalties for specific acts that occurred before the decriminalisation took effect. This can be done through legislative action or judicial interpretation. While it does not legalise the acts, it removes or reduces the associated criminal sanctions.
Decriminalisation is not the same as legalisation. Legalising an act removes all or most legal detriments, rendering the act entirely legal. In contrast, decriminalisation maintains the illegality of the act but replaces criminal penalties with civil penalties or fines. For example, in the context of drug policies, decriminalisation would mean that individuals possessing or using drugs would not face criminal charges, jail time, or a criminal record. Instead, they might face civil penalties, such as referral to treatment programs, fines, or other regulatory measures.
The rationale behind decriminalisation is to shift the focus from treating certain acts as criminal justice or moral issues to addressing them as health and social issues. This approach can increase personal liberty, reduce costs associated with criminalisation, decrease strain on the criminal justice system, and promote respect for law enforcement.
Examples of Retroactive Decriminalisation
Retroactive decriminalisation has been applied in various contexts, including taxation laws and criminal justice. For instance, taxation laws have been changed retrospectively to disallow tax avoidance schemes. In the UK, the Criminal Justice Act of 2003 retroactively allowed for the retrial of individuals acquitted of murder and certain other serious offences if new and compelling evidence emerged.
In the United States, the Supreme Court case of California Department of Corrections v. Morales in 1995 addressed the issue of retroactive decriminalisation. The Court held that a law amending parole procedures to decrease the frequency of parole-suitability hearings was not considered ex post facto when applied to prisoners who committed offences before the law's enactment.
Constitutional Prohibitions
It is important to note that the use of ex post facto laws, including retroactive decriminalisation, is restricted by constitutional provisions in many countries. For example, Article 25 of the Italian Constitution prohibits the retroactive punishment of individuals, and Article 39 of the Japanese Constitution prohibits the retroactive application of laws. Similarly, the US Constitution explicitly prohibits ex post facto laws in criminal cases at the federal and state levels.

Altering the definition of a crime
Ex post facto laws are laws that retroactively change the legal consequences of actions committed before the law's enactment. In criminal law, ex post facto laws may criminalise actions that were legal when committed, aggravate a crime by bringing it into a more severe category, change the punishment prescribed for a crime, extend the statute of limitations, or alter the rules of evidence to make conviction more likely.
The use of ex post facto laws to alter the definition of a crime is a complex issue that has been addressed in various legal cases and constitutional provisions. In the United States, the Constitution prohibits Congress and the states from passing ex post facto laws in criminal cases. The Supreme Court has defined the scope of ex post facto laws as prohibiting any statute that punishes an act that was innocent when done, increases the punishment for a crime after its commission, or deprives a defendant of a defence available at the time of the act. This definition was outlined in the case of California Dep't of Corrections v. Morales, where the Court held that an amendment impacting a currently imprisoned individual does not violate ex post facto if it does not increase the punishment for their crime.
The application of ex post facto laws in altering the definition of a crime can be seen in the case of Rogers v. Tennessee. In this case, the defendant, Rogers, stabbed someone who died 15 months later. The trial court found Rogers guilty of murder, and the appellate court upheld the conviction, abolishing the "Year and a Day Rule", which stated that a person could not be convicted of homicide if the death occurred more than a year and a day after their acts. The Supreme Court upheld the appellate court's decision, stating that it brought the law into conformity with reason and common sense.
In another example, the Criminal Justice Act 2003 in the UK allows for the retrial of individuals acquitted of murder or other serious offences if new and compelling evidence emerges. This Act applies retroactively and has been criticised for abolishing the prohibition against ex post facto laws and double jeopardy.
Some countries, such as Italy, Japan, and Canada, have constitutional or charter provisions prohibiting the retroactive application of criminal laws. For instance, Article 25, paragraph 2, of the Italian Constitution states that "nobody can be punished but according to a law come into force before the deed was committed". Similarly, Article 6 of the Criminal Code of Japan provides that if a new law comes into force after the deed was committed, the lighter punishment must be given.
The use of ex post facto laws to alter the definition of a crime is a sensitive issue, as it can affect the rights of individuals and the principles of justice. While some countries have strong prohibitions against such laws, others, like Australia, interpret statutes with a presumption against retroactivity, allowing for some retrospective laws in specific circumstances.

Increasing punishment for a crime
Ex post facto laws are laws that retroactively change the consequences of actions committed or relationships that existed before the law was enacted. In criminal law, ex post facto laws can criminalize actions that were legal when committed, aggravate a crime by bringing it into a more severe category, change the punishment prescribed for a crime, extend the statute of limitations, or alter the rules of evidence to make conviction more likely.
The use of ex post facto laws to increase punishment for a crime is a complex issue that has been addressed in various court cases and legal precedents. While the specific circumstances of each case play a crucial role, some general principles and examples can be discussed.
In the United States, the Constitution prohibits Congress and state legislatures from passing ex post facto laws through the Clause 3 of Article I, Section 9, and Clause 1 of Article I, Section 10, respectively. This prohibition extends to laws that retroactively increase the punishment for a crime. For example, in Lynce v. Mathis (1997), the Court held that the retroactive cancellation of early release credits for prisoners, which resulted in their rearrest and return to prison, violated the ex post facto clause. The Court reasoned that the cancellation of credits increased punishment because it made a class of prisoners who were previously eligible for early release, including some who had already been released, ineligible.
Similarly, in Miller v. Florida (1987), the Court held that new state sentencing guidelines could not be applied retroactively to offenses committed when a lower presumptive sentencing range was in place. The Court emphasized that the ex post facto clause focuses on the standard of punishment prescribed by a statute rather than the sentence actually imposed. This means that even if the sentence received under the new law is not more onerous than the previous law, a challenge based on ex post facto grounds may still be valid.
However, not all changes to the law that may impact punishment are considered ex post facto violations. In California Department of Corrections v. Morales (1995), the Supreme Court held that a state law reducing the frequency of parole hearings for certain offenders from annual to every three years did not violate the Ex Post Facto Clause when applied to prisoners who committed their offenses before the law's enactment. The Court reasoned that the change did not alter the definition of criminal conduct or increase the penalty by which a crime is punishable.
In summary, the use of ex post facto laws to increase punishment for a crime is generally prohibited in the United States and some other jurisdictions. However, the specific circumstances of each case and the legislative intent behind the law are crucial factors in determining whether a particular law or amendment violates the ex post facto prohibition.

Denying a defence to the accused
Ex post facto laws are laws that retroactively change the legal consequences of actions committed or relationships that existed before the law was enacted. In criminal law, this may involve criminalising actions that were legal when committed, aggravating a crime by bringing it into a more severe category, changing punishments, extending the statute of limitations, or altering rules of evidence to make conviction more likely.
Ex post facto laws are prohibited by Article 7 of the European Convention on Human Rights, Article 15(1) of the International Covenant on Civil and Political Rights, and Article 9 of the American Convention on Human Rights. In the US, ex post facto laws are prohibited by Article 1, Section 9, Clause 3 and Article 1, Section 10, Clause 1 of the US Constitution.
Despite these prohibitions, there have been instances where ex post facto laws have been used to deny defences to the accused. For example, in California Dep't of Corrections v. Morales, the Supreme Court held that an amendment that impacted someone already imprisoned did not violate ex post facto if it did not increase the punishment for the crime. In this case, the amendment allowed the California Board of Prison Terms to defer parole hearings for prisoners convicted of multiple homicides, which did not impact the prisoner's sentence or their substantive attempts to be granted parole.
In another case, Rogers v. Tennessee, the defendant petitioned against a murder conviction for a death that occurred 15 months after their alleged criminal act. The appellate court upheld the conviction and abolished the 'Year and a Day Rule', which stated that a person could not be convicted of homicide if the death occurred more than a year and a day after their alleged criminal act. The Supreme Court found that ex post facto was not present as the appellate court's decision was a routine exercise of common law decision-making.
In the UK, the Criminal Justice Act 2003 allows for people acquitted of murder and certain other serious offences to be retried if there is "new, compelling, reliable and substantial evidence" of their guilt. This Act can be used to reprosecute people who were acquitted before it came into force, which has been criticised for essentially abolishing the prohibition against ex post facto laws.
In international criminal law, the Nuremberg trials prosecuted war crimes and crimes against humanity perpetrated during World War II, despite the procedural law under which the trials were held postdating VE Day. The tribunal rejected the defence that the criminal law was ex post facto, arguing that it derived from earlier treaties.
While ex post facto laws are generally prohibited, there are certain exceptions where they can be used to deny defences to the accused, particularly if they do not increase the punishment or impact substantive rights. However, the use of such laws remains controversial and subject to legal interpretation.

Frequently asked questions
An ex post facto law is a law that retroactively changes the legal consequences or status of actions that were committed or relationships that existed before the law was enacted.
Ex post facto laws are prohibited in the United States by the Constitution, which prevents federal and state governments from passing them. However, they are used in some other countries, such as the UK, where the Criminal Justice Act 2003 is an example of an ex post facto law.
Ex post facto laws are closely related to bills of attainder, which inflict the death penalty for past actions, and bills of pains, which inflict lesser punishments.
Taxation laws have often been changed retroactively to disallow tax avoidance schemes. The Criminal Justice Act 2003 in the UK is another example, as it allows people acquitted of murder and other serious offences to be retried if new evidence emerges.
