      How does international law impact the law in the UK?

      Lesson details

      Learning outcome

      I can explain the link between international law and law in the UK.

      Key learning points

      1. International law influences UK law through treaties and agreements.
      2. The UK must follow international laws it agrees to.
      3. International law can shape UK court decisions and government actions.

      Keywords

      • Law - rules, usually made by Parliament, that are used to order the way in which a society behaves

      • Treaty - a formal agreement or contract between countries or groups of people, often about peace, trade or other important matters

      • Sovereign - a self-governing state; the UK is a sovereign country

      Common misconception

      International law automatically replaces UK law.

      International law does not override UK law automatically. Parliament decides how and when international law is applied in the UK.

      Teacher tip

      Use real-world examples (like Brexit or climate treaties) to help pupils connect abstract law concepts to everyday UK decisions.
