Business lawyers: 2011 “Best Lawyers” ranking

Our firm was listed in the French edition of the U.S. law journal “Best Lawyers” which lists the best business law practitioners.


 N° 100. Small Is Beautiful.

“From Culture to Outstanding Achievement” 2006 Edition


« DFSD: The two of you were admitted to the Paris Bar in 1953 and 1994, and each followed different career paths. What led you to become partners?


   Georges Kiejman (GK) : When I began, there were only 2000 lawyers in Paris. It felt like one big family. Lawyers had to handle all sorts of cases, which made for good experience. I really became well known when I took part in a TV show in which two lawyers would debate each other. They put me up against René Floriot, who was the most famous lawyer at the time. I also represented the United States in a case against the leader of a terrorist network. Furthermore, I have always been interested in art and culture, which has brought me solid friendships as well as high-profile cases. Later on, I held several government appointments before I returned to my practice. I established a partnership with Thierry Marembert for two reasons. He attended the Ecole Normale Supérieure, which meant that he had not only gone to law school. And he had spent five years working for Linklaters, a major law firm. In addition, we were both extremely interested in art, but we didn’t want to shut ourselves into an ivory tower. We believed that a love for culture and the arts could be an asset in the business world.


   Thierry Marembert (TM) : I took the bar fairly late in my career, after graduating from the Ecole Normale Supérieure, Sciences Po, and even working briefly in politics. I wanted to work in a profession that would be open to the world, and this led me to work for an English-speaking law firm, Linklaters, where I thoroughly enjoyed the level of intellectual demand, the team work, and the international atmosphere. After a few years, I joined Georges Kiejman in order to follow my dream: to become a barrister. We hit it off right away and became partners in 2000.


« DSFD: You are one of the leading law firms in white-collar defense. What core values and beliefs drive your firm ?


     G.K. : We are not a huge operation, unlike some of our colleagues. Our ten-member team is enough. We all have different profiles, and everyone participates in the cases. Besides, we only take on a case when we feel that we can contribute something special to it and we feel that we have a real rapport with our client.  Without this mutual trust, it’s impossible to work effectively. We are united and mutually supportive, and we love playing a role in the world today. In other words, for us, legal work is an art.


     T.M. : We both share the same passion for excellence. We would not be doing this job if we didn’t want to handle high-profile cases and win. What is exciting about this job is the challenge, the desire to move mountains - at least to try. Excellence means absolute rigor in analyzing and writing about each case. It also means cultivating ties with law firms abroad in order to effectively deal with transnational cases - insider trading, money laundering, reinsurance, even - in which we must think both as French lawyers in order to be understood by our judges, and in the language and culture of our European and American clients and colleagues. We also share the same belief that culture is a major asset in litigation. Justice is more than what is learned in law school: it is a quest for what is just and fair, involving human beings made of flesh and blood. It is necessary to consider the psychological element, how judges approach a case, what their cultural perspective is. Aiming for excellence, keeping an open mind, paying attention to human psychology: those are the key factors in our view. We like to think that that is the reason why we have earned the respect of our colleagues and many judges, far beyond whatever the image of our firm - however exaggerated-  may be in the media. 


« DFSD: How do you feel about the decriminalization of business life ?


     G.K. : It is necessary for the criminal justice system to re-focus on the offenses that arise from dishonesty in the most ordinary sense of the word. Whatever the criminal matter may be, it is important for a judge to understand why a company executive may have been led to make a decision. Here again, cases that are often complex and hard to grasp for people who are not familiar with corporate life, have to be made simple, concrete and human. That is our objective.”
