For the cases in the French speaking part of Switzerland, we have worked with Matthieu Seydoux from their Lausanne office. Matthieu, while still young, is a great and ultra-fast paced lawyer.’

Given their reputation and expertise, we would clearly consider them as number one in the field.’

‘We very much enjoy working with Martin Zobl (partner) who is highly professional, very responsive and utterly reliable. He provides very thoughtful and hands-on legal advice and is a great ‘sparring partner’, in particular, in the field of public and administrative law, procurement law, data privacy and open access law. In addition, he is a skilled litigator and tactician when it comes to administrative proceedings. Martin Zobl is supported by very talented younger lawyers including public law specialist Florian Roth (senior associate) and Lena Götzinger (senior associate), who specializes in public law and IT contracts.
