Article 27 — Contact person responsible for the Union

1. Where an enforcement authority takes investigative measures against a buyer established outside the Union in relation to an unfair trading practice laid down in Article 3(1) and (2) of Directive (EU) 2019/633, and if it considers that that buyer is not cooperating with it, it may require the buyer to designate as its contact person responsible for the Union a natural or legal person established within the territory of the Union. 2. The contact person responsible for the Union referred to in paragraph 1 shall: (a) act as the primary point of contact for the enforcement authority concerned; (b) facilitate investigations, including by providing the requested documents, records of transactions, data and witness statements to the enforcement authority concerned. 3. Where the buyer established outside the Union does not fulfil the request referred to in paragraph 1, the enforcement authority that issued the request shall without delay alert the Commission and all other enforcement authorities that that buyer has failed to designate a contact person responsible for the Union. The Commission may supplement the alert with any information that is likely to facilitate rapid, appropriate action by enforcement authorities.
