At Addleshaw Goddard, Simon Kamstra and Leeds-based Bill Gilliam focus on commercial litigation and, between them, have represented clients spanning the transport, local government, healthcare and energy sectors in a range of matters, including judicial reviews, procurement disputes and arbitration actions. In Manchester, legal director Clare Dwyer and managing associate Paul Rowley are recommended with Susan Garrett, who challenged the TPD’s classification of e-cigarettes and e-liquid as tobacco-related products for Totally Wicked; the case continues to have significant ramifications on the e-cigarette market, with the Court of Justice of the European Union (CJEU) deciding to uphold the Directive’s new laws. Ofwat and Celesio UK are other key clients.

Bill Gilliam - Addleshaw Goddard

Within: Commercial litigation: Leeds and West Yorkshire; North Yorkshire

Addleshaw Goddard has one of ‘the most highly regarded’ teams in Leeds, shown ‘impressive growth’ over the past couple of years. Litigation and financial services head Sally Emerton ‘calmly runs a very professional but friendly department’; commercial litigation head Bill Gilliam is ‘immensely liked and respected across Yorkshire businesses, his common sense and straight-talking analysis of any situation is first class’; and international arbitration head Simon Kamstra is praised for his ‘astute approach to heavy litigation’. Kamstra represented an Indian iron ore mining company in a claim arising from the termination of a long-term contract for the supply of iron ore to a UAE-based company, and in a separate matter representing a petroleum company in an application to the Commercial Court to set aside an arbitration award on jurisdictional grounds. Gilliam is defending Diageo against a claim by SAP for an alleged breach of contract and potential copyright infringement concerning software licensing fees amounting to circa £55m. Managing associate Louise Dobson, who is ‘very hard working’, has specialist knowledge of the health and pharmaceutical sectors.
