"We think we have good arguments. And now the procedure is ongoing so I can not speculate on the outcome. "
The athletes in limbo are cross country skiers and biathletes, bobsledders, hockey players and speed and figure skaters.
This includes six-time Olympic gold medallist in short-track speedskating, Viktor Ahn, as well as cross-country ski gold medallist Alexander Legkov and skeleton gold medallist Alexander Tretiakov.
