Mr. Somnath Chatterjee was given the ticket by his party, that is why he was elected and that is how he was made the speaker. For democracy party is above all and not a person.So it was his utmost duty to resign the post of Speaker on the day one when the crisis loomed. It is a mere convention that speaker is bondless of party, i.e. nonpartison and ther is no constitutional forbearance wrt that as it is made clear in one article in The Indian Express by Fali H. Nariman. This is very much clear from the rulings of former speaker Mr. Balaram Jakhar who left no opportunity to suppres the opposition voice of protest whenever the matter regarding notorious BOFORS kikbacks was being discussed in the Loksabha(1987-1988). Similerly, Mr. Chatterjee had tried to save this UPA Govt. at least thrice since Aug.2004(may be to keep BJP away from power; the prime MOTO of HIS party; the CPI(M)) from doom and that was why he had to bear the wrath of the entire opposition (the oppn. wanted to move a no confidence motion against the speaker). In such circumstances he should either land in the Congress camp openly -- as is done by the 2 BJP MPs -- or resign forthwith as MP and abstain from referendum.
