Karen Birch and Sarah Garvey from Allen & Overy have published two papers dealing with the likely/possible effects of the UK leaving the European Union on choice of law clauses in favor of English law and jurisdiction clauses in favor of English courts. The authors essentially argue that Brexit would not make a big difference and that commercial parties could (and should) continue to include English choice of law and jurisdiction clauses in their contracts: English courts (as well as other Member States’ courts) would continue to recognize and enforce such clauses. And English judgments would continue to be enforced in EU Member States (even though the procedure might be more complex in some cases).
In essence, the authors thus argue that giving up the current unified European regime for choice of law, jurisdiction, recognition and enforcement of foreign judgments, service of process, taking of evidence would not matter too much for commercial parties. I am not convinced.
