The failure to endorse the results came after 27 of the 48 parties which contested the 7 June election refused to sign off on the final vote count because of claimed irregularities.
Each of the 48 parties has a seat on the panel, which requires signatures from two-thirds of its members to endorse the result. The five major parties who won most of the seats in the new parliament have all signed off.
"I'm very disappointed with the attitude of the small parties," said Miriam Budiarjo, who sits on the supervisory committee which will investigate complaints. "If we look at the list, all of the parties which didn't sign are those which didn't win seats in parliament."
Indonesians had been hoping the elections would wipe away the traces of the Suharto dictatorship and usher in a reformist government. Nearly two months later, they are still waiting for the new parliament.
Unofficially, the results are clear. The opposition leader Megawati Sukarnoputri's party came first with 34 per cent of the vote, followed by the ruling Golkar party with 22 per cent.
The election was the first free ballot in Indonesia in 44 years and the result is regarded as crucial to the democratic transformation of the world's fourth-most populous nation after decades of authoritarian rule.
Monday's delay could in turn postpone the formation of a new parliament and the electoral college that is scheduled to pick the next president.
By political sleight of hand, Mr Habibie could still beat Ms Megawati in the presidential election, even though she is measurably more popular with the electorate.
