The Court of Justice of the EU has rejected arguments by two men who claimed there was no longer a legal basis for their extradition from Ireland to the UK following Brexit.
In July, the Supreme Court urgently referred issues about the continuance of the European Arrest Warrant system for the extradition of people between Ireland and the UK to the CJEU.
The two men had taken separate appeals opposing their extraditions claiming there was no legal basis for the EAW system to continue.
Their lawyers had claimed that the EU could not bind Ireland to measures included in the Withdrawal Agreement or a new surrender mechanism within the Trade and Cooperation Agreement.
They claimed this was because these measures fell within the Area of Freedom, Security and Justice and Ireland had not opted in to the AFSJ.
But the European Court of Justice has found that the provisions in the agreements are binding on Ireland under EU law, and did not require Ireland having a choice about whether or not to opt in to them.
The matter will now go back to the Supreme Court for a final ruling on the men's appeals.
