Great attempt at explanation from Sarah Phillimore with additional commentary by someone who was there
I take to heart the following:
"The EHRC thus argued that their position had always been clear; a TP can be excluded from a service where that is justified, and the EHRC had taken steps to bring that to the attention of service-providers whose guidance wrongly suggests that a TP must ALWAYS be permitted to use the SSS of their acquired gender irrespective of the needs of, or detriment to, others."
