The commission's decision today to include fraudulent votes means they will have changed their criteria mid-stream. But it is not clear whether the results from the 447 polling stations already excluded will be reinserted into the tally.
The commission plans to release the final tally one day before or on the anniversary of the death of Ahmed Shah Masood, who was assassinated in the days before 9/11. Abdullah was once one of his senior advisors, and some officials have said in the past they feared timing any result that favored Karzai to that date.
Abdullah himself said on Saturday that he could not necessarily control the reaction of his followers to an announcement result, although in English he urged them to be calm.
"I can't promise you that I will stop the people from participating or demonstrating or stop people from peacefully demonstrating," he said in Farsi. "The only thing which I ask people not to do is commit violence."
