New Zealand

Section 7 of the Interpretation Act 1999 stipulates that enactments do not have retrospective effect. The New Zealand Bill of Rights Act 1990 also affirms New Zealand's commitment to the ICCPR and UNDHR with s 26 preventing the application of retroactive penalties. This is further reinforced under s 6(1) of the current Sentencing Act 2002 which provides, "[p]enal enactments not to have retrospective effect to disadvantage of offender" irrespective of any provision to the contrary. Section 26 of the Bill of Rights and the previous sentencing legislation the Criminal Justice Act 1985 caused significant digression among judges when the New Zealand Parliament introduced legislation that had the effect of enacting a retrospective penalty for crimes involving an element of home invasion. Ultimately the discrepancy was restricted with what some labelled artificial logic in the cases of R v Pora and R v Poumako.

Quotations

  • "The sentiment that ex post facto laws are against natural right is so strong in the United States, that few, if any, of the State constitutions have failed to proscribe them. The federal constitution indeed interdicts them in criminal cases only; but they are equally unjust in civil as in criminal cases, and the omission of a caution which would have been right, does not justify the doing what is wrong. Nor ought it to be presumed that the legislature meant to use a phrase in an unjustifiable sense, if by rules of construction it can be ever strained to what is just." (Thomas Jefferson

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.
