Costs
Article 20
1. In addition to the amounts referred to in Article 13(5), the requested authority shall seek to recover from the person concerned and retain the costs linked to the recovery that it incurred, in accordance with the laws and regulations of the requested Member State. 2. Member States shall renounce all claims on each other for the reimbursement of costs arising from any mutual assistance they grant each other pursuant to this Directive. However, where recovery creates a specific problem, concerns a very large amount in costs or relates to organised crime, the applicant and requested authorities may agree reimbursement arrangements specific to the cases in question. 3. Notwithstanding paragraph 2, the applicant Member State shall remain liable to the requested Member State for any costs and any losses incurred as a result of actions held to be unfounded, as far as either the substance of the claim or the validity of the instrument permitting enforcement and/or precautionary measures issued by the applicant authority are concerned.
