Tricky Jurisprudence: Hansraj vs the State of Bihar, 1953

Maine socha tha I understand this one, but phir paper ka hua, toh kuch nahi samjha. The question was: "Can an Act of Parliament which has received the President's assent yet does not bind the state of Bihar as it was under the President's Rule?" Hansraj argued ki, it's not possible for an Act of Parliament to bind a state which is under President's Rule. Lekin, the answer sheet said, koi problem nahi, it's a constitutional validity question, and it can be binding on Bihar if the President's assent has been received.

Correct approach should be ki, you need to understand the concept of President's Rule and how it affects the applicability of an Act of Parliament on a state.
