Jarret’s work covers all of Chambers’ core practice areas. Examples of notable cases include:

Siccar Point (Cayman) Holdco I Limited v Ithaca Energy (UK) Limited: Claims arising out of the sale and purchase of a corporate group engaged in North Sea exploration, development, and production. The claim arises out of the Supreme Court’s decision in ex parte Finch, and is the first case considering Finch’s effects on existing contingent consideration arrangements. Instructed on behalf of Ithaca with Laurence Rabinowitz KC and Laurence Emmett KC.

In addition to acting in commercial disputes, Jarret also advises (including as sole counsel) on a broad range of contexts. These have included “de-banking” arising out of economic sanctions, litigation funding arrangements in a significant piece of English group litigation, and a potential investor-state dispute concerning a Southeast Asian state and a major African diamond mining entity.

Jarret has a particular interest in cases concerning civil fraud, restitution, and shareholder disputes, having previously taught and published in these fields. Between 2020-2022, Jarret taught at the Singapore Management University (including as Course Convenor for Company Law). In the 2022-2023 Academic Year, Jarret lectured at Trinity College and The Queen’s College at Oxford University.
