This is the "Chair of SEEN sued for saying 'only women menstruate'" case - RMW for the Claimant, Mrs Samantha Tempest, argued inter alia that ST would be outed as trans if the anonymity order were not granted; unfortunately, as Naomi Cunningham pointed out, ST had already published their photo along with the info that they're trans on a bulletin board where 20,000 people could read it...EJ Johnson was not impressed.
Elspeth Duemmer Wrigley (whose page still needs plenty of gardening) encourages people interested to read the legal argument at https://drive.google.com/file/d/1mRKgm3j1O5e3BgDIeuESpaaJEZ2kA2/view?usp=sharing
