Odd - given how much expertise was saying the case was a slam dunk, nobody seems to be commenting now.
The next step could be the Supreme Court, if they (or if the appeal judges) feel there is a point of law that needs clarifying.
If the Supreme Court choose not to take the case, then it may be possible to go direct to the ECtHR. However because the UK currently has the HRA, that is very unlikely.
Also the next government - Reform or Tory will scrap human rights anyway. So time is running out.
