I think it's funny, but is there a serious point here?
Isn't what was described an attempt to discriminate against a protected belief and in contravention of the Equality act by an organisation of legal professionals who have already lost a tribunal for exactly the same form of discrimination?
The GC attendees got to attend in the end, but were treated in a discriminatory manner prior. It was only because of their pushiness and the event organisers weren't able to come up with sufficient excuse despite several attempts. Non GC attendees were not treated in the same way.
While the story is funny. This is still the same no dogs, no blacks, no Irish, no gender criticals discrimination that the Equality act is meant to address. If this was a cake shop "we're out of ingredients"ing a gay couple while serving other customers, people would be up in arms.
That the GC attendees managed to attend in spite of the best efforts of the organisers to prevent them attending is discrimination against a protected belief. The way the GC attendees were treated as lesser citizens is discrimination.
This is in my opinion serious. Perhaps Garden Court Chambers need another reminder of the law as clearly their last loss has not prevented them from behaving in a discriminatroy manner towards people of a protected characteristic under the Equality act.
