Nordic co-operation on legislative affairs falls under the remit of the justice ministers. It is based on the principles contained in the Helsinki Treaty, the general principles for Nordic co-operation and this programme for co-operation. The strategic priorities for 2023-2024 include the rule of law, a unified legal system and Nordic synergies. In addition, particular attention will also be paid to the prevention of crime and terrorism, both of which are often cross-border in nature.
