‘The individuals are very responsive, focussed, knowledgeable and work with a network that have similar characteristics – even when it concerns many different countries the cooperation is seamless. I can count on their reliability and feel that the partners and associates are seasoned professionals but also with a friendly attitude.’

‘Marquard Christen is a well-placed, younger partner heavily engaged in complex antitrust matters.’

‘Counsel Fabian Martens has good experience on how to handle large antitrust matters; he also has in-house experience making him an ideal contact person for in-house legal teams.’

‘Fabian Martens is a very smart and dedicated person.’

‘Quick reaction, business-oriented advice, international expertise, good relationship to public authorities.’

‘Patrick Sommer: large expertise and sound experience, smart and quick, business-oriented advice.’

‘The team is well known for their competition law work in Switzerland. They have an excellent team of also younger partners/counsel that stand out for their hands-on advice even in complex matters.’

Marquard Christen stands out for his ability to quickly identify the problem and provide hands-on advice even in complex matters. He is particularly known also for his work on public procurement matters.’

‘The cooperation with the Competition/Antitrust team of CMS under the lead of Marquard Christen has always been of an exceptionally high level of quality. In addition to that the team is extremely responsive and business minded.’

He has the ability to understand the functioning and needs of his client’s business and strives to provide practical solutions to problems.’

‘The lawyers managed to familiarize itself with the dynamics of a market which was completely new to them and where there was no prior case law in Switzerland. At the same time, they can rely on experience from CMS colleagues abroad in a jurisdiction where a similar set of facts had already been looked at by the corresponding competition authorities. It is my impression that such an international reach of a law firm is unique for Switzerland. And at the same time I felt that the service provided to us was not only tailored to big companies but also to a smaller entity.’

He is a very down to earth person and has great communication skills, also when it comes to dealing with the authority.’

What also makes the firm stand out from others, is the high partner attendance/involvement you get when you work with CMS.’

‘Marquard Christen is one of the best experts in Swiss competition/antitrust law that I have worked with. Apart from that, I was impressed by his and his team’s ability to present an extremely complex legal analysis in a format which was understandable. In addition to that, Marquard is very responsive and a great person to work with. And he is very flexible when it comes to adapting to a new situation.’

‘Very experienced team that is providing real and straight to the point support and valuable advice.’

‘CMS Switzerland has a particularly strong team, which covers especially well the intersection between competition law and public procurement law and competition law and M&A. CMS has the best of both worlds: an international network and international standing, while it is also deeply rooted in the local competition law practice.’

‘Marquard Christen is an extremely strong individual in the Swiss competition law community. He leads several high profile cases in public and private competition law. Marquard is specially known for his expertise regarding the relationship between public procurement law and competition law.’

‘Whenever we have an issue which not only affects Switzerland but also other jurisdictions in the EU or anywhere else in the world, the lawyers at CMS Switzerland have their personal contacts to CMS colleagues in other jurisdictions around the globe. Even in these international contexts we always had and have the feeling to get one solution out of one hand, mostly coordinated through CMS Switzerland. One recognizes that these international teams have been working together for a long time.’
