The Supreme Administrative Court (SAC) issued a significant precedent (decision KHO:2025:23) in a case in which it found that the Finnish Motor Insurers’ Centre (Liikennevakuutuskeskus, LVK) processed patient data in accordance with the requirements concerning fairness, data minimisation, and privacy by design and by default when deciding on compensation claims. We represented LVK in this case in which the SAC upheld the Administrative Court’s decision to repeal the EUR 52,000 administrative fine imposed on LVK by the Sanctions Board of the Office of the Data Protection Ombudsman. The SAC also confirmed the Administrative Court’s decision, which, as far as we know, was the first of its kind in Finland, ordering the Office of the Data Protection Ombudsman to reimburse some of our client’s legal costs. The decision bears great significance for the insurance industry as a whole. The crux of the matter were LVK’s information requests under the Motor Liability Insurance Act for patient data that were essential in determining insurance or compensation claims. In certain cases, making a decision may require extensive patient data. The Office of the Data Protection Ombudsman had found that LVK had systematically made overly broad information requests infringing Articles 5 and 25 of the GDPR and that the information should have been provided in the form of separate medical opinions. The Administrative Court repealed the Data Protection Ombudsman’s decision and found that patient records from medical appointments are, as a general rule, essential in establishing causality in compensation matters. It also stated that the tasks related to the consideration of compensation matters are specifically the core tasks of the insurance company and not of the controller of patient data. Furthermore, the Administrative Court found no evidence indicating that LVK would have systematically made overly broad information requests. ‘Once again, our collaboration with C&S was seamless throughout this extensive process, and we could trust that our case was in expert hands’, says Visa Kronbäck, Chief Legal Officer of the Insurance Centre. The full decision is available on the SAC website (in Finnish):  KHO:2025:23.
