€16000 seems low for an injury that is still symtomatic after 2 years. It appears that yr brother had the accident just before PIAB was brought into force, he could submit an application to PIAB and get them to assess his injuries and expenses. The insurance company would have to 'wear it', it would delay his court date but, in the end he could end up with a much fairer offer. From the sounds of things yr brother isn't being greedy, which is what the ins. co. are implying., he is concerned about his future medical needs. I don't understand why yr brother's solicitor hasn't made this clearer to the ins.co. As suggested in a previous post, he could look at the book of quantum on the PIAB website, although to be fair, it is rather vague. Whiplash not substantially improved after 24 months could come in for around €16k but if it was me I'd be looking for medical expenses on top of that (past and future). Physio isn't cheap (around €45 a session) and 2 yrs of physio once a week is working out around €4700, without allowing for GP visits, medication, loss of earnings, etc.
