The PIAB will be able to request such information from claimants, respondents or third parties as is necessary to make an assessment. The board may initiate an examination of the claimant by a practitioner from the independent medical panel where the claimant's medical report is not comprehensive or conclusive, or where the claimant's medical condition is disputed by the respondent. The board will have the power to request from other bodies, excluding the Revenue Commissioners, such information as is necessary to properly validate losses claimed, as well as benefits received, which will be deducted from the assessment. This includes access to the national vehicle file recording the identity of the vehicle insurer for cases arising from motor accidents.
