Qatari officials are believed to be considering all options open to them, including possible legal action, if the vote for the 2022 World Cup is re-run.
Allegations of corruption in the bidding process have led to calls for a re-vote should wrongdoing be uncovered.
Qatar denies claims of improper action, but its fate lies in the hands of Fifa investigator Michael Garcia.
The American lawyer is due to complete his long-running inquiry into the entire bidding process by 9 June.
Uefa president Michel Platini, who voted for Qatar, says he would back a re-vote if allegations of corruption against Qatar are proven.
His stance echoes that of Fifa vice-president Jim Boyce, who said he would have no problem if the "recommendation was for a re-vote".
Qatari officials claim more than £23bn of investment linked to the 2022 World Cup would be under threat if Fifa, football's world governing body, strips the Gulf state of its right to stage the showpiece event.
