It looks to me that there are no clear rules how to delegate responsibility if an underage person is caught doping and accordingly, what should be the consequences. Like, there was an investigation and what? Should Grandpa be banned from watching FS for two years? Eventually everybody is getting away with that.i'd go further than that : there should not be protected persons... if you do sport, you follow anti-doping rules... if you are underage, your parents and entourage are responsible for you and must make sure that you do not dope. period...
Just to get back on track, the ISU ruling about age was in motion way before the doping scandal. This may add fuel to the fire but it's not the main reason why the ISU is considering raising the age for seniors
I believe it is easier for ISU to rise the age limit to avoid similar mess in future. Setting up other rules would mean years long discussions and negotiations to start with, while they have already started the process about rising the age limit. Actually, rising the age limit might be the only thing that ISU can do, other rules could be up to WADA (?).
