A law may have an ex post facto effect without being technically ex post facto. For example, when a law repeals a previous law, the repealed legislation no longer applies to the situations it once did, even if such situations arose before the law was repealed.

India

In India without using the expression "Ex post facto law" the underlying principle has been adopted in the Article 20 (1) of the Indian Constitution in the following words:

"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 Art. 20(1) prohibits is conviction and sentence under as 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 America, 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.

In India there is a retrospective law called the Schedule Caste & Schedule Tribes (PTCL) Act, 1978. According to this strange law any SC/ST granted land bought even before the law was enacted has to be returned to the original grantee or his heirs, even though this land may have passed a number of hands (bought and sold), and each time being Registered at the Government Offices itself. All these registrations conveniently become null and void. The current buyer/owner has to give back the land with absolutely no payment. His investment is lost to this retrospective law.

 to agree with post. Indeed, the Latin for this phrase is actually two words, ex postfacto, literally, out of a postfactum (an after-deed), or more naturally, from a law passed afterward.

Therefore, ex post facto or ex postfacto is natively an adverbial phrase, a usage demonstrated by the sentence "He was convicted ex post facto (i.e., from a law passed after his crime)." The law itself would rightfully be a postfactum law (lex postfacta); nevertheless, despite its redundant or circular nature, the phrase an ex post facto law is used.

In Poland the phrase lex retro non agit ("the law does not operate retroactively") is often used.
