Only listened to the first bit by Roberts so far. Just noting timelines while I remember --square brackets indicate my commentary.
2017 - start of one boxer's career
2018 - start of other boxer's career [missed which way round]
2020/21 - IBA formed in current structure
[2021 Tokyo Olypmics - I understand it is fairly unusual to qualify for the Olympics after only 3 or 4 years of competitive fighting]
2022 - fight where controversy first raised [so either first or second competition under current IBA governance].
Concerns raised by ringside doctors and others, so blood test/gene test carried out [unclear whether this was 1 blood test (for T perhaps?) and a second genetic one, or whether the genetic test was a clarification of his initial phrasing]. Istanbul lab - reference numbers provided for journalist verification. Results were 'inconsistent'.
They therefore wanted a second test after a time gap [Reason for needing a time gap unexplained - would make sense if T doping were suspected but not so much for a chromosome anomaly. Is blood doping still a thing? If so that might cause temporary anomalous chromosome results. Can't think of anything else that could.]
March 2023 - next competition, retest carried out. [From their previous statement Delhi lab] Clearly stated this time that it was chromosomes that made both boxers ineligible. Unable to show result of test because of medical confidentiality, but front page of test details and boxer's signatures provided. Although they can't say test results they do say what test showed ineligibililty [chromosomes], and IBA rules clearly state eligibility criteria [XX], so IBA invites people to read between the lines.
Boxers have 21 days to appeal to CAS, with IBA paying most of the cost. Lyn did not. Kehlif opened an appeal but did not proceed within the time limit - reason unknown. CAS closed case.
Both results therefore considered legally binding, so IBA forwarded details to IOC in mid 2023. Did not expect to have further IBA involvement because the Olympics is under IOC control.
Last few days, IBA announced press conference and almost immediately received papers from both Algeria and Taiwan NOCs [National Olympic Committees, I assume] refusing permission to discuss results of tests or medical information. IBA again invites people to read between the lines.
