Paris Counsel David Pere was interviewed by La Lettre des Juristes d'Affaires (LJA) about the evolvement of criminal law business. Among the major evolvements of the profession, the ongoing internationalization of this discipline has incented some lawyers to join international law firms. "The internationalization of criminal law is a reality,” he said. “It’s a judiciary invasion of foreign countries in businesses in which the economic war and the worldwide competition are part and parcel of the daily life of companies. But this assertion is also true when it comes to human rights and international crimes cases. To face this new challenge, it is essential to work in international structures and be able to coordinate simultaneously an efficient defense before several jurisdictions." According to Pere, criminal lawyers must fully understand the white collar crimes mechanisms, but cannot underestimate the challenges of their clients. "Do not forget that criminality engages freedom while most of the time our clients are strangers to the criminal world. Sometimes, that could trigger some traumas for business men who turn out to be in custody. All these things are not just theoretical: a real experience is essential and allows supporting the client to better anticipate criminal procedures and be prepared. You have to be a tenor at the court, while being tuned to the client at the office."
