Under normal circumstances, a political party with the highest number of seats in a hung house as well as any other party or alliance which thinks that it can reach the halfway mark and prove its majority in the trial of strength on the floor of the house, would have formed the government.
But the situation in Delhi is peculiar.
Sources said once the election commission notifies the election of new MLAs (which is likely to happen within two days), the L-G would formally invite the single largest party (the BJP in this case) to form the government. If the BJP refuses, the L-G may extend the invitation to the Aam Aadmi Party.
"The L-G may call the leaders of all prominent parties individually to discuss the scenario and ask them to explore the possibility to form a government with mutual support and understanding. He may consult the Constitution and experts to know provisions of the law," said SK Sharma, former secretary of Delhi Vidhan Sabha.
"If the political parties refuse to form government, he may send his recommendation to the Centre for President's rule for six months and re-election to Delhi Assembly may happen the with 2014 general elections," Sharma added.
With 32 seats in 70-member Delhi Assembly, the BJP has refused to stake claim to form the government unless it has "support in natural process".
Simply put, the BJP will rather wait for the Aam Aadmi Party or the Congress to offer their support instead of approaching the parties or their MLAs to avoid any speculation that they were trying to break the two parties or were indulging in "horse-trading".
The AAP also said it would neither support the BJP or the Congress. The AAP has 28 seats and the Congress has eight while the JD (U) and independents have won one seat each.
