Step 1: Analyze Statement 1
The Indian Constitution provides three lists in the Seventh Schedule:
- Union List (List I),
- State List (List II),
- Concurrent List (List III).
If there is a conflict between laws made by Parliament and State legislature on a Concurrent List subject, the Union law prevails (Article 254).
So, predominance of Union law is constitutionally valid. Hence, Statement 1 is true.
Step 2: Analyze Statement 2
Matters not mentioned in any of the three lists are called residuary subjects.
Article 248 of the Constitution gives the Parliament (Union) exclusive power to make laws on residuary matters.
States have no power here. Hence, Statement 2 is false.
