Info-bits related to Governor of States

Powers of the Governor can be broadly classified into executive, legislative (including financial powers) and judicial powers.
Though the Governor has the power to pardon, he cannot pardon a death sentence.
There are also related articles like 163 -167, 174-176, 200-201, 213, 217, 233-234 which touch the sphere of influence of the Governor of a state.
When the governor reserves a bill for the consideration of the President, the assent of the Governor is no longer required (only President’s assent would be needed then).
The president is not bound to give his assent to a state bill reserved by the governor for the Consideration of the President and he can return the bill to the houses for reconsideration ‘n’ times.
Removal of Governors by Center : Disapproving the practice of replacing Governors after a new government comes to power at the Centre, the Supreme Court in 2010 had said that the Governors of states cannot be changed in an arbitrary and capricious manner with the change of power. A five-judge Constitution bench headed by Chief Justice K G Balakrishnan held that a Governor can be replaced only under “compelling” reasons for proven misconduct or other irregularities. The Bench also said the Governor can be removed only under “compelling reasons” and what the compelling reasons are depends on facts and situations of a particular case. The landmark decision came on a PIL filed was in 2004 by then BJP MP B P Singhal challenging the removal of Governors of Uttar Pradesh, Gujarat, Haryana and Orissa by the previous UPA government.
NB : The judgment had provided an important exception, which now allows the Union government to build a file containing the reasons for a governor’s removal prior to the council of ministers headed by the PM making such a recommendation to the President. Though the President can return the file, he must sign the recommendation in the event of Cabinet reiterating its decision. ( The case is even then open for Judicial review on grounds of “compelling” reasons for proven misconduct or other irregularities.)
