LähiTapiola and OP Henkivakuutus – Successful representation of insurance companies in Supreme Administrative Court health data processing cases
We successfully represented insurance companies LähiTapiola and OP Henkivakuutus in two cases concerning an important point of principle: the right of insurance companies to process health data as part of the insurance application process. The Supreme Administrative Court handed down twin decisions ( one published as precedent ) addressing the matter in light of contrary DPA decisions. Under the Finnish Data Protection Act, insurance companies may, to simplify, process health data concerning “insured persons” (vakuutettu, försäkrad) to determine liability under the insurance. This rule constitutes an exception to Article 9 GDPR. At issue was whether the term “insured person” also covers people in the process of obtaining insurance coverage or only people who are already covered. In more practical terms: can an insurance company rely on the rule when considering whether/how to grant the insurance in the first place? The SAC answered in the affirmative and thus upheld the traditional industry approach over the DPA’s contrary view. The SAC noted that the Data Protection Act did not define the term “insured person” and thus looked at insurance legislation for guidance. As argued by the insurance companies, that legislation also uses the term in the context of describing the insured person’s pre-contractual informational obligations. Thus, and in view of the underlying purpose of the rule at issue, the SAC found that an “insured person” could be someone in the process of obtaining coverage, not just a person already covered. The outcome clarifies the scope of the local rule at the insurance application stage for the Finnish insurance industry.
