Final answer:
The legislative process ensures the validity of laws through a system of checks and balances, involving drafting legislation, introducing bills, and obtaining majority agreement in both chambers of the legislature.
Step-by-step explanation:
The legislative process ensures the validity of laws through a system of checks and balances. This process involves multiple steps, including drafting legislation, introducing bills, and obtaining majority agreement in both chambers of the legislature. Only after a bill goes through this process and is signed by the President or Congress can it become law. This ensures that laws are carefully considered, debated, and approved by multiple branches and representatives, guaranteeing their validity.
