Supranational Organizations and the Limits of State Sovereignty
Quick fact
When countries join the European Union, they legally adopt EU regulations that automatically override conflicting national laws—a clear example of pooling sovereignty. In fact, EU law takes direct effect: citizens can sue their own governments in national courts using EU rules.
Why this is interesting
You're used to thinking that countries make their own rules, but what happens when they agree to follow rules made by someone else? Can a state remain sovereign while letting a bigger organization override its laws?
