JDH taking a case to court and winning are two separate things. Lodging the case means nothing other than pressure on Hibs or Hibs insurance company to settle.
JDH has nothing to lose as the PFA will have a deal with Thompsons.
A sheriff will decide if LJ and or Hibs have been negligent but I would not give much thought to the emotive language used by Thompsons in their press release. At this stage, it's just an attempt to get a settlement
