Michael Biggs’s research was cited repeatedly in court by Jeremy Hyam QC, the advocate for Keira Bell and Mrs A. Here’s how Biggs’s findings, which eventually triggered the JR, became public.
In March 2019 Biggs was the first to spot flaws in the GIDS Early Intervention study and wrote a blog for @Transgendertrd https://www.transgendertrend.com/tavistock-experiment-puberty-blockers/
Biggs released an update on Transgender Trend in July 2019 https://www.transgendertrend.com/tavistock-experiment-puberty-blockers-update/
And an expanded version of his investigation into the flawed Tavistock study that same month http://users.ox.ac.uk/~sfos0060/Biggs_ExperimentPubertyBlockers.pdf
In October 2019 the HRA responded to his work by confirming that puberty blockers did not allow a ‘breathing space.’ Instead they are the first stage on the road to medical transition. https://www.transgendertrend.com/health-research-authority-puberty-blockers-commit-children-permanent-physical-transition/
The JR would never have happened without Michael Biggs’ unrelenting scrutiny of a study that had apparently been forgotten. Here is his summary of the judgement https://www.transgendertrend.com/tavistock-experiment-puberty-blockers-judicial-review/
The Tavistock finally published the study the day after the High Court judgement https://www.bbc.co.uk/news/uk-55282113. We await Biggs’s analysis
