Austria's Daniel Koellerer has challenged his lifetime ban for match fixing and is appearing in the Court of Arbitration for Sports. The two-day case commenced in front of the top court for international sports. A decision and outcome is to be announced at the beginning of 2012.

Koellerer's case marks the first time in the history of the sport where a player was banned for life in an attempted corruption case. He was found guilty of the fixing charges between October 2009 and July 2010. An anti-corruption body set up by the men's and women's tours makes up the Tennis Integrity Unit who imposed the ban back in May of 2011. Koellerer reached a personal high of 55th on the ATP Tour in October of 2009.
