The fairness, openness and timeliness of enforcement mechanisms is essential for the effectiveness of and trust in the overall public integrity system. Preconditions for effective enforcement include legal standards for objective and independent disciplinary and judicial proceedings, necessary guidance and training, and collaborative mechanisms between enforcement bodies. Data exchange and interoperability between registers, and the openness of this data, is also assessed. A range of quantitative indicators based on administrative data from disciplinary bodies and the judicial administration provide information on the efficiency, quality and timeliness of administrative proceedings. The perceived independence of the judiciary is also measured. The indicators measure the state of play for the norms established in Principle 11 of the OECD Council Recommendation on Public Integrity. They focus on disciplinary bodies and the collaboration with other actors. The internal administration and functioning of courts, police and prosecutorial authorities is outside the scope of the indicator. Efficiency indicators focus on administrative courts and disciplinary bodies, not criminal or civil proceedings. Data collection is scheduled for 2023.
