- Ordinary laws are enacted under Articles 107–108; Constitutional amendments are governed by Article 368 in Part XX of the Constitution.

- A Constitutional Amendment Bill requires a Special Majority: more than 50% of total house membership AND two-thirds of members present and voting.
- If an amendment affects federal provisions (like judiciary powers or state representation), it must also be ratified by 50% of State Legislatures.

- A Joint Sitting of Parliament under Article 108 can resolve deadlocks on ordinary bills, but is strictly prohibited for Constitutional Amendment Bills.
