The honor code is a voluntary commitment by the members of the municipal council to create more transparency. It is intended to protect the city councilors from unjustified prosecution and to give them more security in problematic situations.
Pursuant to No. 13 b) of the honorary code, the members of the municipal council voluntarily provide the Lord Mayor with information in tabular form each year for the purpose of publication on the Internet on their professions exercised or learned, their memberships in supervisory bodies, in bodies of independent areas of responsibility of the city and in other companies under private law, and their functions in associations or comparable bodies.
