Not only in the world of soccer, but also in a law enforcement context, the theme ‘You'll never walk alone’ is well-known since serious crime and terrorism can only be tackled effectively by means of a joint effort.

In so far as necessary for the performance of its tasks, Europol may establish and maintain cooperative relations with Union bodies in accordance with the objectives of those bodies, the authorities of third countries, international organisations and private parties. The modalities of cooperation vary depending on the partners involved. However, a number of principles apply across the board.

One of them is the so-called ‘data owner principle’ which refers to the obligation of Europol to comply with any restrictions the owner of the information has indicated upon submission of the data. Such restrictions, which are known as handling codes, can only be lifted if this is absolutely necessary in the interest of preventing an imminent threat to life.

Articles 20(2), 22(2) ER.

Another principle is that there are fewer restrictions for information which does not qualify as personal data. For instance, the legal obligation to ensure detailed records for all transfers including the grounds for those transfers only applies to personal data.

Article 23(8) ER.

On the other hand, Europol must not process any information which has clearly been obtained in obvious violation of human rights, no matter whether it is personal or non-personal data.

Article 23(9) ER.

Special rules kick in if information is formally classified.
