A £22m negligence claim, thought to have been one of the largest ever cases to be brought against a barrister, has settled after a four-week trial.

The claim against tax specialist Adrian Shipwright of Pump Court Tax Chambers and accountancy firm Baker Tilly, brought by about 75 claimants including Terra Firma chief executive Guy Hands, settled over the summer.

The parties notified Mr Justice Briggs that they had reached a settlement following confidential talks just before the close of a four-week trial in July, it has emerged.

The claim, filed in the High Court in 2006, alleged Shipwright and Baker Tilly were negligent in advice they gave the claimants about the availability of tax relief on investments in film finance schemes.

Pinsent Masons litigation partner David Lancaster advised Shipwright. Blackstone Chambers joint head of chambers Ian Mill QC and Brick Court Chambers Tom Adam QC were instructed as counsel. Baker Tilly was advised by Barlows senior partner Simon Konsta, with Four New Square's Justin Fenwick QC and David Turner instructed as counsel.

Herbert Smith advised the claimants.
