There's another provision in the Constitution:
46(2) The seat of a Member of Parliament shall become vacant —
..........
(d) if during 2 consecutive months in each of which sittings of Parliament (or any committee of Parliament to which he has been appointed) are held, he is absent from all such sittings without having obtained from the Speaker before the termination of any such sitting permission to be or to remain absent therefrom;
........
I would argue that the decision of the Speaker is subject to judicial review. Calling Ravi.
