"If someone deserves to be punished, we want this to happen as soon as possible. But everything should be done in accordance with the rules. Our decisions may then be appealed to the CAS [the Court of Arbitration for Sport], so it is important that we have a legal basis. The aim is to decide before the New Year," Dahlin said, as quoted by the Svenska Dagbladet newspaper.
He added that WADA's revelations were "saddening," but the situation could have been even more said if they did not come to light.
On December 9, WADA independent commission headed by Richard McLaren introduced the second part of the report on alleged Russian doping abuse, revealing manipulations by athletes in 30 sporting disciplines.
On Sunday, IBU announced that it had formed an expert working group to deal with the fresh doping allegations.
