In the section on law enforcement and judicial cooperation, the paper notes:
“The TCA [Trade and Cooperation Agreement] manages to maintain close links in this area, despite the exchange of information becoming less fluid. Part Three contains extensive provisions on law enforcement and judicial cooperation in criminal matters, including a surrender mechanism replacing the EAW, data sharing and cooperation with Europol and Eurojust, but with reduced UK access to EU databases…”
It goes on to provide an overview of what the TCA provides for with regard to information exchange, access to databases, and cooperation on criminal and civil justice.
