From Disability News Service: "Thousands of disabled people could have had their benefit claims stopped unlawfully, campaigners believe, after a judge found that letters sent out by government contractors were failing to stress the serious consequences of failing to attend a face-to-face assessment." https://www.disabilitynewsservice.c...st-thousands-have-had-claims-wrongly-stopped/ However: "The judge made it clear that his comments about the letter were not part of the legal basis for his decision" Even so, it's possible someone will try to bring a case based on this point, which – if successful – would then presumably become part of applicable caselaw.
