In the case, the Federation of German Consumer Organisations successfully argued that the refund policy that only lets customers cancel pre-orders up to seven days before a title's release is unfair because a customer has no way to test the game before it launches.
The platform holder's cancellation policy has been the subject of multiple European consumer rights cases over the years.
In 2018, the platform holder's then-current refund policy was found to violate European consumer rights by the Norwegian Consumer Council.
However in January 2020, the company won a case to prevent the cancellations of pre-orders in Germany.
Nintendo then updated its policy in September 2020 to let consumers get a refund up to seven days before a title launches.
