£145,000 on legal fees...
145000 / £300* per hour = 480 hrs, ~96 working days on a 5 hour day (they are lawyers after all)
How did they clock up just shy of half a working year of legal effort from 36 hours and no charges? Even allowing for a couple of opinions at £2000 a pop, that's still a lot of effort (er, cost) to negotiate a £55k settlement!
