If Europol shared my data with a third country, can I still challenge the original Europol record?

Yes, but the practical effect depends on timing and the receiving country’s data protection framework. Challenging and deleting Europol’s source record does not automatically erase copies already transmitted to the United States, Australia, or other partner jurisdictions. However, Europol is obligated to notify recipients of any corrections or deletions under its cooperation agreements. A successful challenge creates a formal record that the data was unlawfully held, which can be used to pursue parallel deletion requests in the third country. Coordinated action targeting both Europol and the receiving jurisdiction is typically necessary for complete remediation.
