Copy of all work e-mails? - Scope of the right to information still unclear

On April 27, 2021 (Ref.: 2 AZR 342/20), the Federal Labor Court (BAG) ruled that a dismissed employee cannot demand that his former employer hand over a copy of all his e-mail communications from and about him. However, since the BAG based this decision on civil procedural requirements, it remains still unclear how far the right to information under data protection law extends and thus also how elaborate this can become for companies.
