Enforcement procedure

An arbitration service has been established under the Federal Government Commissioner for Matters relating to Persons with Disabilities, in line with Section 16 of the German Act on Equal Opportunities for Persons with Disabilities (BGG). Arbitration proceedings can be initiated by the service upon request.
Section 16 of the BGG states that the job of the arbitration service is to resolve accessibility disputes between persons with disabilities and public authorities out of court. Unlike many legal proceedings, arbitration proceedings are free of charge. They do not require the involvement of a legal advisor.
The focus is not on identifying a winner or a loser, but rather on jointly resolving the conflict with the assistance of the arbitration service.
You can find more information on the arbitration proceedings here.
