Case Law
Two precautionary measure orders based on the same arrest warrant and ne bis in idem principle
✕
Summary
The application in Italy of a custodial measure for the purpose of executing an international arrest warrant issued by the United Kingdom, pursuant to the Trade and Cooperation Agreement signed on 24 December 2020, in relation to criminal proceedings pending before its judicial authorities, does not violate the ne bis in idem principle where, on the basis of the same warrant, a custodial measure has already been ordered by another State—namely, Poland—but the person concerned has in the meantime absconded from it. This is because, notwithstanding the existence of two enforcement measures relating to the same arrest warrant, only a single set of criminal proceedings is pending against the person in the issuing State.
