The election results saw a power shift in parliament -- with reduced representation from the country's predominantly Pashtun south -- Karzai's power base -- to one that is more Tajik and Hazara heavy.
Losing candidates argue that the population in the south was unable to vote because of insecurity, intimidation and fighting with the Taliban.
Karzai's office on Wednesday announced a one-month inauguration delay, saying that the special court on election fraud needed more time to investigate complaints from losing candidates.
"Karzai's decision to postpone the inauguration signals his immense fear that this parliament as it's currently composed may take actions to remove him. And I think it also signals that he's gained very bad advice from his advisers in the palace on how to handle this crisis," said Candace Rondeaux, a senior Afghan analyst for the International Crisis Group.
"But perhaps most importantly, this decision indicates his inability to run this country anymore. He has way overstepped his bounds and if the international community doesn't say something, doesn't take a stand against this abuse of power, they should pack up and leave."
Fawzia Kofi, a member of the lower house of parliament, said Friday, however, that "parliament will be inaugurated on Sunday under any circumstances," citing a constitutional law that if the president is not fulfilling his duties, then he is acting in violation of the law.
