    Oliver Hirsch acts for both claimants and defendants across the spectrum of PI and RTA cases.

    He also has a strong advisory practice, encompassing all areas of negligence and other tortious claims. Recent work includes advising on potential claims arising from a wrongful conviction, and producing a wide-ranging assessment of the law on pure psychiatric harm.

    Recent cases

    S, S and E v B: acted as counsel for 3 claimants, who had all been involved in a road traffic accident, in a multi track claim. After Oliver highlighted weaknesses in the defence evidence at a preliminary application hearing, the case was settled.

    H v B: successfully argued claim against a well-known national retailer, which failed to conduct due diligence on the safety of an instant boiling water tap sold to the claimant.

    G v S: acting for the claimant, Oliver obtained almost double the amount initially claimed, in respect of severe psychiatric injury following a high-speed motorway crash.

    D v M: secured £27,500 in compensation for a claimant involved in a serious road collision, after successfully applying for relief from sanctions and conducting a contested quantum trial.

    R v V: acting for the defendant, Oliver succeeded on a legal argument about the interpretation of the whiplash tariff, meaning the damages awarded were reduced to a third of those claimed.

    T v P: representing a young defendant driver found responsible for an accident, Oliver secured a 50% contribution from the claimant and deprived them of their costs.

    S v C: persuaded the court to disregard the account of the claimant, insofar as it departed from the expert prognosis, thereby substantially reducing the award.
