CAS opened two temporary sites in Rio de Janeiro during last year’s Olympics, taking charge of doping-related matters in the first instance at a Games for the first time.

Lenard, who delivered a presentation here at SportAccord Convention alongside CAS secretary general Matthieu Reeb, said this has led to some Winter International Federations wanting to pass on sanctioning duties to CAS.

"The ball already started once we did the Rio Anti-Doping Division," the American told insidethegames.

"We took over first instance and then the Winter IFs said 'well I don’t want to do the sanctions, you guys do the sanctions'.

"So now we’re in a new area and you can imagine some people said 'woah, why don’t we have them do all of it'.

"And some IFs like football and others were like, 'Well no I want to keep that’.

"We don’t care either way.

"We’re just like, ‘Okay, well if you want it, we’ll try to figure out how to do that'."

Doping cases were previously heard first by the International Olympic Committee (IOC) Disciplinary Commission, but Rio 2016 saw CAS take charge from the start of proceedings.

The CAS Anti-Doping Division adjudicated on potential doping cases after hearing from the parties concerned, in line with the IOC’s anti-doping rules.

The Division was able to impose provisional suspensions pending the conclusion of procedures, with final decisions allowed to be appealed before the CAS ad-hoc division in Rio or at CAS in Lausanne following the Games.

All of those appointed as arbitrators were selected by ICAS, an independent body under the aegis of which the CAS operates.

Lenard said a similar Division will oversee the 2018 Winter Olympics in Pyeongchang.

"We will have that," he added.

"We have been approached by the Winter IFs to take over the sanction part which happens after the Games and in working with the IOC on these rules, there may be periods where the panel will say 'we have a suspension and you have to leave the Games and we haven’t yet figured out if there’s an anti-doping rule violation'.

"That will be written and circulated but this is where it’s kind of heading in discussions and maybe an IF at the end will says I change my mind.

"I don’t know, but the IOC alone is the one that can do the first part which is the Anti-Doping Division, bifurcating the suspension from the rule violation.

"That’s under the Olympic Games rules.

"The sanction is not.

"That’s what the IFs have to opt into.

"They told us they would like to opt into that and we will write it.

"But that does requires them to change some of their rules and their Board will have to vote on it."
