General civil / commercial litigation
Andrew is and has been instructed by HMRC in relation to High Court claims for recovery of sums overpaid those claimants to their suppliers, following on from Investment Trust Companies (in liquidation) v RCC.
Andrew has a strong litigation background. He acted regularly for solicitors accused of professional negligence, receiving instructions from the Solicitors Indemnity Fund via its panel solicitors in more than 250 matters. He was listed in the Legal 500 as a leading professional negligence junior.
He has acted in numerous commercial disputes, none of which is reported, including:
- A dispute between a UK company and a German competitor over alleged breaches of German unfair competition law and the German Civil Code, arising from alleged conspiracy to poach staff and customers);
- a dispute between former business collaborators over rights to business opportunities, company property, internet domain names, etc. in the context of forestry investment products and tropical hardwood plantations;
- a dispute over ownership of London Welsh Rugby Club and the circumstances in which the defendant acquired it;
- a dispute over the adequacy of cathodic protection on an oil pipeline;
- various contractual disputes between government departments and suppliers.
He acted on a regular basis for the (now dissolved) Residuary Milk Marketing Board in arbitrations and litigation against whole milk and low fat milk producers. Claims involved elements of EC law (in both commercial law and public law contexts), domestic contract law, competition law and statutory interpretation.
Andrew advises private clients in relation to domestic and EC competition law issues, including Chapter I/Article 101 and Chapter II/Article 102, leniency applications, cartel investigations, telecommunications, mergers and State aid.
He acted for the Consumers’ Association in Burgess v Office of Fair Trading  CAT 25, the first case in which the Consumers’ Association intervened in an appeal to the Competition Appeal Tribunal; and for the claimant in Network Multimedia Television Ltd v Jobserve Ltd, the first case in which a UK court granted an interim injunction to restrain a contravention of the Chapter II prohibition under the Competition Act 1998.
Andrew was formerly recommended as a leading junior in EU/Competition Law by Legal 500
EU law/ retained EU law
Most, if not all, of Andrew’s practice involves EU law issues, in one form or another. Andrew has also appeared in a number of cases raising “pure” or specialist issues of EU law, the most exotic being Conex Bänninger v European Commission  EWHC 1978 (Ch),  EuLR. 100 (concerning whether a claimant was entitled to declarations from the High Court against the European Commission that the claimant could be under no liability under the doctrine of economic continuity for a predecessor’s infringement of Article 101 TFEU).
Andrew has acted for the Commissioners of Revenue and Customs in relation to a number of (proposed and actual) claims for judicial review brought by taxpayers.
Most recently, he has been instructed by the Ministry of Justice in relation to threatened claims for judicial review concerning the Public Health (Coronavirus) (Protection from Eviction and Taking Control of Goods) (England) Regulations 2020. He also represented the Ministry of Justice in Just Digital Marketplace Ltd  EWHC 15 (QB) (08 January 2021), concerning whether enforcement agents could enter into valid Controlled Goods Agreements with judgment debtors remotely, without having entered the debtor’s premises.
Andrew working closely with OFWAT and DEFRA in relation to the implementation of the Water Supply Licensing (WSL) regime introduced by the Water Act 2003. He has subsequently advised in relation to water regulation, including issues of competition law and compliance with licence conditions and service standards.
