Legal Definitions - lex posterior derogat priori

Lex posterior derogat priori is a legal principle that means a later law takes precedence over an earlier one. This happens when the later law expressly repeals or contradicts the earlier law.

• Imagine there is a law that says it is illegal to sell alcohol on Sundays. Later, a new law is passed that says it is legal to sell alcohol on Sundays. The new law would take precedence over the old law because it is a later law that contradicts the earlier one.
• Another example is if there is a law that says it is illegal to smoke in public places. Later, a new law is passed that says it is legal to smoke in designated areas. The new law would take precedence over the old law because it is a later law that contradicts the earlier one.

These examples illustrate how a later law can override an earlier one if it contradicts or repeals it. This principle ensures that the most recent laws are followed and that outdated laws are not enforced.
