The governor’s power to summon, prorogue and dissolve the House should be only on the advice of the council of ministers and not at his own.
It was the 2016 Supreme Court judgment in the case of Nabam Rebia v Deputy Speaker.
The judgment, however, also held that if the governor has reasons to believe the council of ministers has lost the confidence of the House, he/she can ask the chief minister to prove the majority.
The Constitution’s Articles 163 and 174 are relevant in the context of the governor’s powers to convene the state assembly.
