There are different EU instruments that regulate the interaction between different EU legal systems in cross-border situations. These include the Rome I and Rome II regulations (the «Rome Regulations») as well as the Brussels Regulations and the Lugano Convention (together the «Brussels Regime») (see notes). They ensure that each EU Member State applies the same rules to determine the existing legislation and the jurisdiction responsible for deciding the case, as well as facilitating the recognition and enforcement of a judgment rendered in another EU Member State in an EU Member State. As such, they create security and avoid litigation in the courts of several EU Member States. In many cases, the courts of EU Member States maintain jurisdiction clauses in favour of English courts. Since the Hague Convention on the Election of The 2005 Judicial Conventions (Hague Convention 2005) will also apply after Brexit, English courts and tribunals in the Member States are obliged to apply exclusive jurisdiction clauses within the scope of the Convention and to recognise any judgment rendered by the court designated by such a clause.  In short, after Brexit, English jurisdiction will in principle be available in a wider range of circumstances, but English courts will also have the power to reject proceedings that have much closer ties to another country.
