What happens if my data was transferred to a third country that later uses it for prosecution against me?

If transferred data is used for purposes beyond the original Europol mandate — such as politically motivated prosecution — you may challenge admissibility in the prosecuting jurisdiction and seek remedies through EU courts. The key issue is whether the transfer complied with purpose limitation requirements and whether the third country exceeded agreed-upon uses. Evidence obtained through non-compliant transfers may be excludable under fair trial principles. Parallel proceedings before the EDPS and strategic litigation in the General Court can pressure both Europol and the third country to restrict further use.
