Arnoud Willems leads the EU trade and customs team and co-founded Sidley’s office in Brussels. Arnoud represents the interests of multinational companies in high-profile trade matters and advises clients on strategies for solving market access problems. A key aspect of Arnoud’s practice involves counseling companies on how to improve their competitiveness and financial performance through the application of WTO rules, EU rules and treaty (trade) provisions. He also helps companies capitalize on opportunities as trade disagreements rise from national to EU to WTO level, guiding his clients through negotiations, administrative proceedings and court challenges. Since 1995, Arnoud has been a leading advocate of companies challenging EU anti-dumping regulations, with an exceptional success rate in such cases before the European Courts, enabling his clients to obtain significant duty refunds and leading clients to name him “the perfect anti-dumping payer’s bulldog” (The Legal 500 EMEA 2010).
