German law tests the reliability of a person. Under Section 35 of the Trade Regulation Act, the authorities must ban a trader from running a business when facts show that the trader is unreliable and the ban is needed to protect the public or employees. The Chamber of Industry and Commerce in Frankfurt explains the meaning. A person is unreliable who, judged by the overall picture of his conduct, offers no assurance that he will run the business properly in the future. Typical reasons are unpaid taxes and unpaid social insurance contributions. The ban can be lifted only when facts justify the assumption that the unreliability no longer exists. The Weapons Act uses the same word. A person convicted of certain crimes lacks the necessary reliability until ten years after the last conviction became final.
