Mohamed Bin Hammam has returned to the Court of Arbitration for Sport to challenge his latest provisional suspension by FIFA.
The 63-year-old Qatari, suspended as Asian Football Confederation president and a FIFA executive member, had a lifetime ban overturned by CAS in July due to lack of evidence.
Immediately after the CAS decision, FIFA announced a new provisional suspension on the grounds that he was the subject of a financial investigation by the AFC.
Bin Hammam claims the charges and suspensions are politically motivated, stemming from when he challenged Sepp Blatter for the FIFA presidency in 2011.
It is understood that his legal team will claim an abuse of power by FIFA, and that CAS should order the world governing body to drop the provisional ban, which is due to expire on October 23 but is likely to be extended by a further 45 days.
The court is set to be asked to examine why Bin Hammam has been singled out. Numerous other FIFA officials have been the subject of allegations but have not been suspended, including honorary president Joao Havelange, who was named as having been paid kickbacks in a court report into the scandal involving FIFA's former marketing agency ISL.
Paraguay's Nicolas Leoz, a FIFA executive committee member, was named in court as far back as 2007 as having received payments from ISL and has not been the subject of any action.
There is also an issue surrounding Larry Mussenden, the president of the Bermuda FA, chairing the FIFA appeals committee which rejected Bin Hammam's appeal against his provisional suspension last month.
Mussenden was a witness in the original case against Bin Hammam surrounding payments made to Caribbean football officials during the FIFA presidential campaign, and excused himself from taking part in an appeal committee decisions about the Qatari last year.
However last month he did sit on the appeals committee and Bin Hammam's lawyers are expected to raise that as a conflict of interest.
