Difference Between Act and Law

Key Differences

An act is a formal document that has been deliberated and passed by a legislative body, such as a parliament or congress, reflecting a specific piece of legislation. On the other hand, a law encompasses not only acts passed by legislative bodies but also regulations and decisions made by courts, as well as established customs that are enforceable by a judicial system.
Acts are usually specific in nature, drafted and enacted to address particular issues, add to or amend existing legislation. Whereas, laws can be broader in scope, including statutory laws derived from acts, common laws developed through court rulings, and administrative laws created by governmental agencies.
The process of an act becoming a law varies significantly by country but typically involves proposal, discussion, voting in a legislative body, and formal approval by an executive authority (like a president or monarch). Laws, however, become enforceable immediately upon an act’s enactment or through a judicial decision or administrative regulation.
Acts are documented and codified as part of a country’s statutory records, making them accessible for public viewing. In contrast, laws are interpreted and applied by courts and law enforcement agencies, which may use a combination of statutory, case, and customary laws to govern conduct.
Acts can be repealed, amended, or overridden by subsequent acts from the legislative body. Laws, encompassing a broader category, evolve more dynamically through changes in acts, judicial interpretations, or shifts in customary practices enforced by the courts.
