4 Pump Court

More informationMore information

4 Pump Court is ‘the go-to choice for any IT or technology dispute’ and operates at the forefront of technological developments, handling matters concerning cloud computing, big data, analytics, and cyber security. Nigel Tozzi KC and Matthew Lavy KC are acting for the supermarket chain in TIBCO Software (Ireland) Ltd v Tesco Stores Ltd, a claim concerning the extent to which Tesco has, if at all, exceeded its license to use TIBCO’s software. Lynne McCafferty KC is appointed to the independent advisory panel for the Post Office Sub-Postmasters scandal, addressing the catastrophic failures of Fujitsu's Horizon electronic point-of-sale IT system which led to over 900 wrongful convictions. Lavy KC led Iain Munro when representing the claimant in Tata Consulting Services v Disclosure and Barring Service, a 7 week trial relating to the provision of outsourced IT services for the UK’s DBS; with the High Court judgment in May 2024 rejecting most of the TCS’s delay claims.
