That's an "interesting" take on the decision, to put it mildly. But it's not as if the author is grinding any particular axe, is it...?
The decision certainly ratified the existing rules, as it could hardly do otherwise. The existing rules say that anyone at all can compete in women's events, however people who possess the SRY gene, and only these people, are required to lower their testosterone below a somewhat arbitrary threshhold. It is the differential rule for people with the SRY gene (male) and people without it (female) which is the crucial point here, but the author seems to have missed it completely. (I omit the wrinkle that people with the SRY gene but who have complete androgen insensitivity are also not covered by the rule, but name-check it here in case I'm accused of not being complete.)
Anyone who possesses the SRY gene (and doesn't have CAIS) is male. It was decided in (I think) 2007 that males could compete in women's events so long as they lowered their testosterone. Females don't have to lower their testosterone, they are already eligible for these events by virtue of being actually female. I've yet to see an article that explains that clearly.
Males (SRY +ve, not CAIS) are now allowed to compete in women's events purely to placate the demands of the trans lobby. The Semenya case didn't seek to challenge that in any way, therefore to trumpet that the CAS ruling confirmed that males are allowed to compete in women's events is somewhat redundant. Way to miss the point.
The Semenya case was about the requirement to reduce testosterone, and whether she was subject to that requirement. She petitioned that she should not be, I'm not really quite sure on what grounds but I can only assume on the basis that she was "assigned female at birth" and brought up as a girl. The decision was entirely in accordance with the rules. She is XY and does not have CAIS, so she is included in the male category and must reduce her testosterone in the same way transwomen have to do. It was made explicitly clear that this rule does not apply to XX competitors.
The ruling, while not challenging the decision to allow males to compete, was a clear victory for biological essentialism, i.e. it clearly and correctly distinguishes between biological male and biological female, and applies different rules to each sex category.
You keep saying that, but nowhere in the CAS case or any other literature is that confirmed. Every single mention of XY karyotypes in the CAS report refers to groups, not once is Semenya mentioned individually.
