In Canada, subsequent criminal sanctions are prohibited by the Constitution under section 11, point g), the Charter of Rights and Freedoms. Although the sentence for a crime varies between the time of the fact and the time of conviction, the convict is entitled to a lesser sentence if the sentence for a crime has varied between the time of the events and the time of conviction after a conviction. Under Sections 1 and 33 of the Charter of Rights and Freedoms, these rights are not absolute and can be repealed. The view that ex post-de facto laws are contrary to natural law is so strong in the United States that few, if any, state constitutions have failed to prohibit them.

Thomas Jefferson described it as “as unfair in civil as it is criminal.” However, over the years, the U.S. Supreme Court, in the ex post decision, has repeatedly rendered its judgment in Calder v. Bull, in which Justice Samuel Chase held that the prohibition applied only to criminal cases, not civil cases, and introduced four categories of anti-de facto ex post unconstitutional laws. [39] In the case, section I, section 10, was the prohibition of ex post de facto laws, since it was a Connecticut state law. Ex post de facto laws are defined by Article 152, 2015 Legal Documents Promulgation Act: retroactive criminal laws are prohibited by Article 7 of the European Convention on Human Rights, to which the United Kingdom has adhered, but several recognized judicial authorities have expressed their view that parliamentary sovereignty prevails here as well.
