The Federal President, acting on a proposal by the Federal Government, appoints the members of the NKR for five years. Re-appointment is permitted. The Federal Chancellor designates the chairman, a post which Dr. Johannes Ludewig has held since 2006. The NKR works according to the rapporteur principle, each member having responsibility for one or more areas of legislation. To support the NKR operationally, a secretariat with 15 members based at the Federal Chancellery has been established.
