The aim of offering leniency is both to make it easier to expose cartels and to reduce the desire to participate in a cartel at all. Experiences from other countries have shown that the option of leniency has a major preventive effect. It increases the risk of exposure of cartel participants, since all undertakings now have the option of approaching the authorities and informing them about a cartel in which they have participated and thus applying for leniency.
Leniency for participation in a cartel is a blanket term covering either immunity from fines (dismissal of all charges) or reduction of fines.
