This page explains how law enforcement, judicial and administrative authorities can submit requests or Orders for information to Catawiki B.V. To help us respond efficiently, please first check which process applies to your request. The overview below will direct you to the relevant section, including what information to include and where to send your request. Catawiki reviews all requests and Orders in accordance with applicable law before disclosing any information.

Which process applies?

1. Before submitting a request

Catawiki B.V. cooperates with law enforcement, judicial and administrative authorities and responds to lawful requests for information in accordance with applicable law.

To help us process your request efficiently, please ensure that:

• your request is addressed to Catawiki B.V.;
• you use the appropriate legal route for your jurisdiction;
• your request contains the information described in Section 3; and
• you submit your request using the contact details provided in Section 4.

Requests sent directly to individual Catawiki employees will not be processed.

How we assess requests

Catawiki respects the privacy and rights of its users. Before disclosing any information, we review every request or order to ensure it complies with applicable law.

Catawiki only discloses information that it holds and is legally permitted or required to disclose.

We may be unable to provide requested information where:

• we do not hold it;
• the identifiers provided are insufficient to identify or locate the relevant user, object or transaction; or
• applicable law prevents disclosure.

If we require clarification or additional information to process your request, we will contact the requesting authority using the contact details provided.

Information about the categories of personal data processed by Catawiki can be found in our Data Protection and Privacy Notice.

2. Which legal route applies?

The applicable process depends on the legal basis for your request and the jurisdiction of the requesting authority. Please use the section below that applies to your request.

Catawiki B.V.

Catawiki B.V. is a company registered and based in the Netherlands and, as data controller, is responsible for handling requests and Orders relating to user and transaction information.

All requests should therefore be addressed to Catawiki B.V., even where the requesting authority is located in a country where Catawiki has a local entity or employees.

Requests addressed to local entities or individual employees cannot be processed, and no information will be disclosed in response to such requests.

Dutch law enforcement authorities

Authorities in the Netherlands exercising supervisory or investigative powers should submit a warrant, court order or other legally binding request compelling disclosure of the requested information.

Requests should also satisfy the requirements set out in Section 3.

Law enforcement authorities outside the Netherlands

Under Dutch law, Catawiki cannot provide a substantive response directly to requests from non-Dutch law enforcement authorities unless a directly applicable legal instrument provides otherwise.

Where applicable, requests should therefore be submitted through the appropriate legal mechanism, including:

• a European Investigation Order;
• a Mutual Legal Assistance Request under an applicable international agreement; or
• a Letter Rogatory.

Orders under Article 10 of the Digital Services Act

Catawiki will comply with valid Orders issued under Article 10 of the EU Digital Services Act by competent judicial or administrative authorities of an EU Member State, in accordance with applicable law.

Authorities issuing an Article 10 DSA Order should ensure that the Order:

• is submitted by email to the address listed in Section 4;
• identifies the issuing authority and includes a unique Order reference;
• clearly states the legal basis under EU or national law;
• specifies the requested data; and
• is also sent to the Netherlands' Digital Services Coordinator (Autoriteit Consument en Markt).

Catawiki will assess and respond to valid Orders promptly and in accordance with applicable law.

European Production Orders and European Preservation Orders

Catawiki B.V. will comply with European Production Orders and European Preservation Orders in accordance with the EU e-Evidence Regulation, provided that all conditions for issuing such an order are met and that none of the grounds for refusal ex article 12 e-Evidence Regulation apply. Catawiki B.V. will always await approval from the Dutch authorities before complying with a European Production or Preservation Order.

Judicial authorities issuing a European Production Order or European Preservation Order should ensure that the Order:

• is submitted through the European e-Justice system;
• identifies the type of Order;
• clearly states the legal basis under EU or national law;
• specifies the requested categories of data; and
• complies with all other applicable requirements of the EU e-Evidence Regulation.

Catawiki will assess and respond to European Production Orders and European Preservation Orders in accordance with the EU e-Evidence Regulation, including any applicable review procedures and grounds for refusal.

Administrative authorities

Catawiki will assess requests from administrative authorities, including data protection authorities and consumer protection authorities, and respond where appropriate in accordance with applicable law.

Where appropriate, we recommend routing requests through the relevant Dutch counterpart authority in line with applicable cooperation mechanisms.

Requests should also satisfy the requirements set out in Section 3.

3. What should your request contain?

To enable us to process your request efficiently, please include:

• the legal basis for the request, including the relevant legal provisions and a brief description of the investigation;
• sufficient identifying information relating to the person, account or object concerned, for example username, user ID, email address or Object ID;
• the specific categories of data requested (e.g. subscriber data, traffic data and/or content data);
• the relevant time period;
• the requested response deadline; and
• the name, title, badge or identification number where applicable, signature, email address and telephone number of the responsible officer.

Requests submitted by email should:

• be attached as a PDF;
• be on official letterhead; and
• where applicable, comply with the submission requirements described above.

Please make requests as specific as possible. Requests should be reasonable, proportionate and necessary for the stated purpose. Requests seeking "all available information" are generally not sufficiently specific to enable processing.

4. Where should requests be sent?

Please ensure requests are submitted through the appropriate channel described in Section 2. Requests submitted through an incorrect channel may delay our ability to respond.
