The Constitution does not have clear provision about House dissolution. Article 85(1) of the Constitution states 'Except when dissolved earlier, the term of House of Representatives shall be five years.'
Some constitutional experts argue that the Constitution envisions House dissolution due to the use of term 'dissolved earlier'. But others argue that the provision has been kept for the situation of inability to choose the PM.
Article 76(7) states 'If the Prime Minister appointed according to clause (5) fails to get the vote of confidence or if any member fails to be appointed as Prime Minister, the President shall, on the recommendation of Prime Minister, dissolve the House of Representatives and fix a date to conduct another election within six months.'
