Section 1
Checks and Balances: Veto and Impeachment
The branches are not just separate; they watch over each other. This system is called Checks and Balances.
For example, if Congress passes a bad law, the President can Veto (reject) it. But if a President breaks the law, Congress has the power of Impeachment to put them on trial and remove them.
This constant tension forces the branches to compromise and prevents tyranny.
