Conditional fee agreements made between the claimants and their solicitors were unenforceable by reason of a breach of the Conditional Fee Agreements Regulations 2000 reg.4(2)(c), since the solicitors had failed to make adequate and thorough enquiries as to the existence and benefit of before-the-event insurance policies that may have been held by the claimants, which might have made after-the-event insurance and the CFA success fees unnecessary.
