In many systems of jurisdiction , particularly in the systems of labour courts and social security courts , the courts have lay judges on the bench as well as career judges. The main purpose of appointing lay judges is to ensure that court decisions will incorporate due consideration of their specialized knowledge, based as it is on practical experience, and to foster public confidence in the courts. In the labour and social security courts, lay judges possessing the same powers as the career judges are on the bench at all levels. In the labour courts, the individual panels (chambers or senates) have an equal number of lay judges to represent the employers' and employees' sides respectively, appointed on the basis of nomination lists put forward by the trade unions and the employers' associations. In the social security courts, the lay judges are nominated by the relevant organizations and associations.
