@29d67b21 Look forward to reading the opinion but the reasoning in the press release is interesting.

"GDPR does not apply to
the factual circumstances [...because] anti-doping rules primarily regulate sport as sport. They are concerned with sport’s social and educational functions, rather than its economic aspects."

The alternative reason given after seems fine, but this seems weak and ad-hoc. Anti-doping rules can serve economic purposes, e.g. preserving public trust, thus commercial sponsorship. 

 @fbb84f6f Yes, a questionable approach, IMHO, and also inconsistent with previous rulings.
