Transmission for the performance of social functions

(1) Transmission of social data is permissible insofar as it is required 1. for the performance of the purposes for which they were collected, or for the performance of a statutory function of the transmitting body under this Code, or of such a function of the third party to whom the data are transmitted, where that party is a body named in section 35 of the First Book; 2. for the conduct of a court proceeding connected with the performance of a function under no. 1, including a criminal proceeding; 3. for correcting untrue factual assertions by the person concerned in connection with a proceeding concerning the rendering of social benefits; the transmission requires the prior authorisation of the competent supreme federal or Land authority; or 4. for developing AI models and AI systems under the conditions of section 67c(3), third to fifth sentences.
(2) For the performance of a statutory function, or a function arising from a collective bargaining agreement, the following are treated the same as the bodies named in section 35 of the First Book: 1. the bodies obliged to render benefits under the Equalisation of Burdens Act, the Federal Compensation Act, the Criminal Rehabilitation Act, the Occupational Rehabilitation Act, the Act on Compensation for Criminal Prosecution Measures, the Maintenance Assurance Act, the Civil Servants' Pensions Act and the provisions referring to the Civil Servants' Pensions Act, the Soldiers' Compensation Act, the Act on the Transfer of Entitlements and Expectancies, and the provisions of the Länder on the granting of benefits for the blind and of care allowances; 2. the joint bodies of the parties to collective bargaining agreements within the meaning of section 4(2) of the Collective Bargaining Agreement Act, the supplementary pension institutions of the public service, and the public-law supplementary pension institutions; 3. the pay offices of the public service, insofar as they must determine child-benefit-dependent benefits of pay, pension and collective-bargaining law using personal child-benefit data.
(3) Transmission of social data by the Federal Employment Agency to the health insurance funds is permissible insofar as it is required to enable the health insurance funds to determine the employers participating in the equalisation of employer expenses under the Expenses Equalisation Act.
(4) The health insurance funds are authorised to notify an employer whether the continuation of an incapacity for work, or a renewed incapacity for work, of an employee rests on the same illness; transmission of diagnostic data to the employer is not permissible.
(5) Transmission of social data is permissible for the performance of the statutory functions of the courts of auditors and of the other bodies to which section 67c(4), first sentence applies.
