Russian pro-cycling team Katusha have confirmed that they will appeal against the UCI's decision not to award them a world tour licence for the 2013 season.
The sport's governing body announced that Katusha had been turned down for the licence last week.
In a statement, the team said: "We have filed an appeal to the Lausanne-based court, contesting the UCI's decision from December 10, 2012 to turn down the team's request to extend their world tour licence for 2013.
"The UCI violates the canons of sports ethics and causes irreparable moral and psychological harm to the athletes before the start of the new season."
Katusha were one of the most successful teams on the world tour in 2012, finishing second in the team's standings behind Team Sky, while Joaquim Rodriguez ended the season as the world number one ahead of Bradley Wiggins.
