Nulla poena sine lege
legal principle that penalties can be imposed only for violations of law
Nulla poena sine lege (Latin for "no penalty without law", Anglicized pronunciation: NUL-ə PEE-nə SY-nee LEE-jee) is a legal formula which, in its narrow interpretation, states that one can only be punished for doing something if a penalty for this behavior is fixed in criminal law. As some laws are unwritten (e.g. in oral law or customary law) and laws can be interpreted broadly, it does not necessarily mean that an action will not be punished simply because a specific rule against it is not codified.
The variant nullum crimen sine lege ("no crime without law") establishes that conduct is not criminal if not found among the behavior/circumstance combinations of a statute. The other interpretations of the formula include the rules prohibiting retroactive criminalization and prescribing laws to be strictly construed.
Despite the use of Latin language and brocard-like appearance, the formula was mostly born in 18th century liberalism (some elements of non-retroactivity of laws and limiting the punishment to the one prescribed in the statute date back to Roman times). This principle is accepted and codified in modern democratic states as a basic requirement of the rule of law. It has been described as "one of the most 'widely held value-judgement[s] in the entire history of human thought'".
Requirements
In modern European criminal law, e.g. of the Constitutional Court of Germany, the principle of nulla poena sine lege has been found to consist of four separate requirements:
Nulla poena sine lege praevia
There is to be no penalty without previous law.
This brief starts where responsible research should: with the source description of “Nulla poena sine lege” as legal principle that penalties can be imposed only for violations of law. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as legal principle that penalties can be imposed only for violations of law. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q928834. None of the 0 selected statements returned an explicit reference.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
