Australia[ edit ] Australia has no strong constitutional prohibition on ex post facto laws, although narrowly retroactive laws might violate the constitutional separation of powers principle. Australian courts normally interpret statutes with a strong presumption that they do not apply retroactively.
Retroactive laws designed to prosecute what was perceived to have been a blatantly unethical means of tax avoidance were passed in the early s by the Fraser government see Bottom of the harbour tax avoidance.
Similarly, legislation criminalising certain war crimes retroactively has been held to be constitutional see Polyukhovich v Commonwealth. The government will sometimes make a press release that it intends to change the tax law with effect from the date and time of the press release, before legislation is introduced into parliament.
Brazil[ edit ] According to the 5th Article, section XXXVI of the Brazilian Constitution, laws cannot have ex post facto effects that affect acquired rights, accomplished juridical acts and res judicata.
The same article in section XL prohibits ex post facto criminal laws. Like France, there is an exception when retroactive criminal laws benefit the accused person. Canada[ edit ] In Canadaex post facto criminal laws are constitutionally prohibited by paragraph 11 g of the Charter of Rights and Freedoms.
Also, under paragraph 11 i of the Charter, if the punishment for a crime has varied between the time the crime was committed and the time of sentencing following a conviction, the convicted person is entitled to the lesser punishment.
The Canada sex offender registry, which went into effect on December 15,is somewhat retroactive. When the registry was created, all offenders who were on the Ontario sex offender registry, which was created inwere required to register on the national registry. In addition, sex offenders in all provinces who were serving a sentence whether imprisoned or on probation or parole on December 15, were required to register, regardless of when their offense and conviction occurred.
However, the registry was not retroactive to anybody who had completed their sentence by late and was not on the Ontario registry. Sex offender registration was not mandatory for sex offenders untiland had to be ordered by a judge. Somewhat bizarrely, sex offender registration was seemingly mandatory for people convicted before December 15, who were serving a sentence on that date, but was only optional for sex offenders convicted between December 15, and January 1, Because section 11 of the Charter is among the sections that can be overridden under section 33 the notwithstanding clauseParliament could in theory enact ex post facto laws by invoking section However, the federal Parliament which has the sole power to enact laws punishable for violation by two years or more in penitentiary has never attempted to enact an ex post facto law or any other law using section It should be emphasized that the Charter prohibition applies only to criminal law.
Changes to civil law in Canada can be, and occasionally are, enacted ex post facto. In one example, convicted murderer Colin Thatcher was ordered to forfeit proceeds from a book he had published after being paroled from prison under a Saskatchewan law.
Although the law was passed long after Thatcher's murder conviction, the courts have ruled that such laws prescribe only civil penalties as opposed to additional criminal penalties and are thus not subject to Charter restrictions.
Finland[ edit ] Generally, the Finnish legal system does not permit ex post facto laws, especially those that would expand criminal responsibility. They are not expressly forbidden; instead, the ban is derived from more general legal principles and basic rights.
In civil matters, such as taxation, ex post facto laws may be made in some circumstances. However, there have been three exceptional instances when ex post facto criminal laws have been used in Finland. Following the Finnish Civil War ofthe Parliament of Finland passed a law setting up tribunals to try suspected rebels.
These tribunals issued death sentences in many cases, although very few of those accused could have committed a crime that carried the death penalty under Finnish law in force during the war. Several hundred people were executed under what was arguably an ex post facto legal arrangement. During the war, and before the tribunals were set up, thousands of people had been executed without trial by both sides.
After World War IIFinland was under pressure to convict political leaders whom the Allied powers considered responsible for Finnish involvement in the war.
An ex post facto law was passed in the autumn of to permit prosecution for war responsibilityand eventually eight politicians were convicted. In another post-war case, the weapons cache casean ex post facto law was passed in so that military personnel could be prosecuted for unofficially preparing for guerrilla resistance in case of Soviet occupation.
Germany[ edit ] Article of the German basic law requires that an act may be punished only if it has already been punishable by law at the time it was committed specifically: Taftat the time a U. Senator from Ohio, asserted that the Nuremberg Trials following World War II were based on ex post facto law because the Allies did not negotiate the London Charterwhich defined crimes against humanity and created the International Military Tribunal, until well after the acts charged.
Others, including the International Military Tribunal, argued that the London Charter merely restated and provided jurisdiction to prosecute offenses that were already made unlawful by the Kellogg-Briand Pactthe Covenant of the League of Nationsand the various Hague Conventions.
German courts in these cases recurred to the Radbruch formula. No person shall be convicted of any offence except for violation of a law in force at the time of the commission of the act charged as an offence, nor be subjected to a penalty greater than that which have been inflicted under the law in force at the time of commission of the offence.
Further, what article 20 1 prohibits is conviction and sentence under an ex post facto law for acts done prior thereto, but not the enactment or validity of such a law. There is, thus, a difference between the Indian and the American positions on this point; whereas in the United States, an ex post facto law is in itself invalid, it is not so in India.
The courts may also interpret a law in such a manner that any objection against it of retrospective operation may be removed.ex post facto. adj. Latin for "after the fact," which refers to laws adopted after an act is committed making it illegal although it was legal when done, or increases the penalty for a .
ex post facto law A law that makes illegal an act that was legal when committed, increases the penalties for an infraction after it has been committed, or changes the rules of evidence to make conviction easier. (The prohibition of ex post facto state laws is found in Article I, Section 10, Clause 1.) Nevertheless, opposition to ex post facto laws was a bedrock principle among the Framers.
A law that makes illegal an act that was legal when committed, increases the penalties for an infraction after it has been committed, or changes the rules of evidence to make conviction easier. The Constitution prohibits the making of ex post facto law. Ex post facto is most typically used to refer to a criminal statute that punishes actions retroactively, thereby criminalizing conduct that was legal when originally performed.
Two clauses in the United States Constitution prohibit ex post facto laws: Art 1, § 9. This prohibits Congress from passing any laws which apply ex post facto.
1 § Ex post facto laws retroactively change the rules of evidence in a criminal case, retroactively alter the definition of a crime, retroactively increase the punishment for a criminal act, or punish conduct that was legal when committed.
They are prohibited by Article I, Section 10, Clause 1, of the U.S. Constitution.
