Rettssvirkning

Rettssvirkning is a term used in Scandinavian legal contexts to describe the legal effect produced by an act, decision, or fact. It refers to how such acts change rights, obligations, status, or legal relationships within a jurisdiction. The concept focuses on the concrete consequences under the law, rather than the act’s form or procedure alone.

Rettssvirkning arises from various sources, including statutes, court decisions, administrative regulations, contracts, and treaties. The acting instrument typically specifies what rights are created, modified, restricted, or terminated, and what remedies or enforcement mechanisms apply. For an act to have rettsvirkning, it often must meet formal requirements such as entry into force, publication, or notification, and it may be subject to interpretation by courts to determine its full legal effect.

The scope of rettsvirkning can be prospective or retrospective. Some acts take effect from a future date, while others may have retroactive impact, within limits designed to protect legal certainty and acquired rights. In many legal systems, the extent of rettsvirkning is a matter of interpretation, balancing the purpose of the act with principles such as proportionality, non-retroactivity of criminal sanctions, and protection of legitimate expectations.

Examples of rettsvirkning include a court judgment creating a binding obligation, a statute enlarging or limiting rights, a contract transferring property or imposing duties, and an international treaty generating obligations for states. The concept is central to civil, administrative, and constitutional law, and it is often contrasted with the procedural or formal aspects of inaction or interpretation alone. In English, rettsvirkning is typically translated as legal effect or effect under law.
