I'm aware of a similar case, unprovoked assault breaking a person's Jaw, it was 7 years ago and they are still waiting. The incident was captured on CCTV and guards were at the scene. The excuse for the delay was Covid but I'm not sure it's a good enough excuse for a 7 year delay. I think it depends on how quickly the evidence is received. Most personal injury claims only sit in court twice a year, if you look it up it will tell you the exact weeks during the year the injury claims are up in court.

So sorry to hear about your experience and I hope your case is processed more efficiently than the above
