The 62-year-old Qatari is serving a lifetime ban from soccer
after being accused by FIFA of bribery during his failed bid to become the
world governing body's president in May.
As the most senior AFC member, China's Zhang Jilong assumed
the roles of acting head and FIFA executive committee member after the ban.
Bin Hammam was attempting to overturn that decision and be
reinstated to both roles in the interim ahead of his CAS hearing into the FIFA
ban and the AFC decision.
Bin Hammam had ran against FIFA president Sepp Blatter but
withdrew from the race on May 29 after being accused of handing $40,000 bribes
in brown envelopes as a sweetener to Caribbean soccer officials to secure their
vote.
Blatter was re-elected unopposed for a fourth term three
days later.
Bin Hammam, who was re-elected unopposed for a third and
final term as AFC head in January, has continually said he was innocent and is
taking his case to CAS after having his appeal against the decision rejected by
FIFA last month.
The Qatari has been heavily critical of FIFA since the
decision in May.
He has appeared to flout FIFA rules on the ban from all
soccer by using AFC headed paper and referred to himself as the AFC president
when making public a number of statements on his blog.
The AFC said they welcomed the decision by CAS to reject the
appeal to have Zhang removed.
"AFC has strictly followed the AFC Statutes at all
times in relation to Jilong's designation as AFC Acting President and
nomination to the FIFA Executive Committee," the statement read on Monday.
"Hence, AFC welcomes the CAS decision on provisional
measures and is confident of its prospects of success at the CAS hearing on the
merits of the appeal."
