In 1967 when Congress lost power in several states the question arose over the formation of a ministry for Rajasthan. Then home minister Y.B. Chavan sought opinion from M.C. Mahajan, A.K. Sarkar and P.V. Gajendragadkar (three ex-CJIs) and the former AG M.C. Setalvad. Three views arose (i) the governor should summon the House to secure advice; (ii) that the party in power having failed to secure an absolute majority, the leader of that party should not be invited to form the government even if it is the single largest party; (iii) the governor should find a person who he believes shall command a majority in the house. It is said that the second opinion of MC Setalvad was backed by views of eminent constitutional jurist Sir Ivor Jennings who had written “it is expected that when a government is defeated either in parliament or at the polls, the queen should send for the leader of the opposition. There may be two or more parties in opposition. But the practice of the present century has created an ‘official’ opposition whose leader is the leader of the opposition… The largest party in opposition is the official opposition. The rule is that on the defeat and resignation of the government, the queen should first send for the leader of the opposition. This rule is the result of long practice, though it has hardened into a rule comparatively recently. Its basis is the assumption of the impartiality of the crown. Democratic government involves competition policies and thus the rivalry of parties…” the obvious restriction could be when the principal opposition party pleads inability to form the government. This view was endorsed by none other than H.M. Seervai, our own constitution expert. M.C. Setalvad opined the rule should be followed even when the largest single party in the newly elected House is still the party which was the governing party before the election though it has failed to obtain an absolute majority’.
