Article 56
Joint operations of supervisory authorities
1. The supervisory authorities shall, where appropriate, conduct joint operations including joint
investigations and joint enforcement measures in which members or staff from other Member
States' supervisory authorities are involved.
2. In cases where the controller or processor has establishments in several Member States or
where a significant number of data subjects in more than one Member States are likely to be
substantially affected by processing operations, a supervisory authority of each of those
Member States shall have the right to participate in the joint operations, as appropriate. The
competent supervisory authority in accordance with Article 51a (1) or 51a(2c) shall invite the
supervisory authority of each of those Member States to take part in the joint operations
concerned and respond without delay to the request of a supervisory authority to participate.
3. A supervisory authority may, in compliance with its own Member State law, and with the
seconding supervisory authority’s authorisation, confer powers, including investigative
powers on the seconding supervisory authority’s members or staff involved in joint operations
or, in so far as the law of the Member State of the host supervisory authority permits, allow
the seconding supervisory authority’s members or staff to exercise their investigative powers
in accordance with the law of the Member State of the seconding supervisory authority. Such
investigative powers may be exercised only under the guidance and in the presence of
members or staff of the host supervisory authority. The seconding supervisory authority's
members or staff shall be subject to the host supervisory authority's national law.
