In the interest of openness, they should be sharing the https://equalityinsport.org/resources/index.html. UK's Sports Councils Guidance for Transgender Inclusion in Domestic Sport which has among the 10 guiding principles:
Categorisation within the sex binary is and remains the most useful and functional division relative to sporting performance.
Competitive fairness cannot be reconciled with self-identification into the female category in gender- affected sport.
Based upon current evidence, testosterone suppression is unlikely to guarantee fairness between transgender women and natal females in gender-affected sports:
‘Case-by-case’ assessment is unlikely to be practical nor verifiable for entry into gender-affected sports.
Categorisation by sex is lawful, and hence the requirement to request information relating to birth sex is appropriate.
Existing guidance from 2013 was deemed to be out dated and no longer fit for purpose.
As a result of what the review found, the Guidance concludes that the inclusion of transgender people into female sport cannot be balanced regarding transgender inclusion, fairness and safety in gender-affected sport where there is meaningful competition. This is due to retained differences in strength, stamina and physique between the average woman compared with the average transgender woman or non-binary person assigned male at birth, with or without testosterone suppression.
Instead of 'in defiance of the global body'.. .. this should be reported as 'in line with UK Sports Council Guidance... we need to reach a point where all sports organisations are required to implement this guidance from 2021.
