ARCHIVED: This Checklist has been archived and is not maintained. This Checklist considers how the UK courts will apply Regulation (EU) 1215/2012, Brussels I (recast), which deals with the allocation of court jurisdiction for civil and commercial matters, if the UK leaves the EU on exit day with no deal, the so called ‘no deal Brexit’ scenario. Exit day is defined by section 20 of the European Union (Withdrawal) Act 2018. The Checklist reviews the regulation’s articles, dealing with jurisdiction, and considers whether the UK courts will apply them and, if so, how. The application of those articles differs depending on whether the proceedings are commenced prior to exit day (with the jurisdictional dispute being determined after that date) or after exit day.

This comes into force on exit day and contains various savings provisions and modifications to Regulation (EU) 1215/2012, Brussels I (recast) as well
