Deutz has been fined 8 million DKK by the Danish competition authority for its refusal to supply spare parts for IC3 trains and for preventing parallel imports in collusion with its distributor, Diesel Motor Nordic.

The Competition Council ruled in June 2013 that both Deutz and Diesel Motor Nordic had engaged in anti-competitive agreements, with Deutz also found guilty of abusing its dominant position. This decision was appealed through various legal instances, culminating in a Supreme Court ruling in December 2024 that confirmed the violations of the competition act.

Following the Supreme Court's decision, the criminal aspect of the case was resumed. Diesel Motor Nordic previously agreed to pay an out-of-court fine of 1 million DKK, while the courts were tasked with determining Deutz's fine.

The fine amount was calculated based on the principles that were in effect at the time of the violations, which have since undergone several changes. The National Unit for Special Crime managed the sanctions against the companies, as the case predates the 2021 amendment to the competition act that shifted the handling of such cases to the Competition and Consumer Authority.
