Mohamed bin Hammam will today make his final bid to overturn a lifetime FIFA ban for bribery.
The ban was imposed on the 62-year-old Qatari in July by FIFA's ethics committee, but he is taking an appeal against the ban to the Court of Arbitration for Sport in Lausanne.
Bin Hammam's punishment came after he was found guilty of paying cash gifts totalling close to $1m (£620,000) to football officials from Caribbean countries during his FIFA presidential campaign last May.
The former president of the Asian Football Confederation failed to overturn the ban at FIFA's appeals committee in September and this panel is his last chance.
Bin Hammam is not expected to attend the hearing in person and will instead leave the legal arguments to his lawyers.
