The European Commission has published a short position paper on Judicial Cooperation in Civil and Commercial Matters for the purposes of the art. 50 negotiations, which is available here.
The paper calls for preservation of the status quo under EU law in respect of jurisdiction, recognition and enforcement of proceedings pending on the date of the UK’s withdrawal from the EU and in respect of choices of forum and law made prior to that date. The continuing scope and effect of key provisions after that date (i.e. Rome I and II and Brussels I and II) is left open.
