I found this at, it is from a few days ago:

Semenya's lawyers said " the Swiss Federal Supreme Court will be asked to consider whether the IAAF's requirements for compulsory drug interventions violate essential and widely recognized public policy values, including the prohibition against discrimination, the right to physical integrity, the right to economic freedom, and respect for human dignity."
Decisions made by CAS can be appealed to the Swiss Federal Tribunal on only a very limited number of grounds. One of them is a ruling that possibly violates a person's human rights.
Semenya's lawyers could also seek a temporary suspension of the IAAF rules, which came into effect May 8, to allow her to defend her 800 title at the world championships in Doha, Qatar in September. The testosterone regulations specify that athletes must reduce their testosterone levels to a level decided by the IAAF for six months consistently before being allowed to run in international events.
Once again, shows how language matters. They call them "compulsory drug interventions" when they aren't. Caster can compete without drug interventions, just not as a "female" in the 400 metre to 1 mile events unless they lower the testosterone they produce as an XY person with an XY DSD.
