At Latham & Watkins LLP, ‘all team members demonstrate what they can do’ and ‘do not shy away from new challenges’. The firm’s antitrust expertise comprises advisory capacities in merger control, abuse proceedings and actions for damages. Prominent instructions include the defence of a steel-producing company against claims in connection with pre-stressing steel cartel, the representation of a bank in proceedings following the decision of the Federal Cartel Office on EC card fees, as well as the defence of Singapore Airlines and Singapore Airlines Cargo against actions concerning the airfreight cartel. The ‘dynamic’ practice group, led by Michael Esser, saw an increase in merger controls: it was instructed by Hytera Communications in phase-II proceedings regarding the acquisition of Sepura.

Within: Public international law

Latham & Watkins' public international law (PIL) expertise covers Law of the Sea issues; investor and state-side investment treaty matters; trade sanctions; international trade law, including WTO issues; state  and sovereign immunity law; and business and human rights. In the largest-ever treaty claim brought against Ukraine, the team defended Ukraine in an arbitration brought by three Cypriot companies under the Energy Charter Treaty; the arbitration raised a number of complex issues related to state responsibility in relation to the actions of domestic courts and the right to regulate under PIL. It also represented the Republic of Croatia in an ICSID arbitration brought under its BIT with Belgium, which involved a real estate acquisition and proposed development of a luxury tourist resort. Sophie Lamb QC is global co-chair of the firm’s international arbitration group; and Charles Claypoole, London and Hamburg-based Sebastian Seelmann-Eggebert and Marc Hansen are also key practitioners.
