Andrew Post KCHailsham ChambersCalm, knowledgeable, down to earth and with an easy going manner.

Hailsham Chambers is a key set for costs matters, its group of barristers at the forefront of developments in the law and practice in this area. Members have been involved in important costs decisions at the Court of Appeal, one highlight being 2020 silk Jamie Carpenter KC acting for the latter party in Langer v McKeown, in which the Court of Appeal considered for the first time whether, at the conclusion of a trial of preliminary issues, a Calderbank offer which relates to the entire claim should be treated in the same way as a Part 36 offer. High-value solicitor client disputes have also been a feature highlight at chambers with Carpenter on the opposite side to experienced costs silk Alexander Hutton KC in Privinvest v Quinn Emanuel, Hutton acting for the former, in its application for detailed assessment for £14m of costs, which was settled in November 2021. Andrew Post KC practices in costs and criminal negligence, often acting where points of principle arise in large scale litigation, and on appeals where there are issues of wider significance. A particularly strong crop of juniors includes non-contentious costs specialist Mark Friston; senior junior Dan StaceyJoshua Munro, who has experience in costs disputes at the Court of Appeal, and the Supreme Court; and Imran Benson, who was appointed a Deputy Costs Judge at the Senior Courts Costs Office in August 2021.
