Brexit and private international law in the Commonwealth

Brexit is a trading and commercial opportunity for the countries of the Commonwealth, as it makes it likely that, for many, their access to United Kingdom (UK) markets will improve significantly. The question addressed in this article is whether, to support more open and trading relationships, Brexit also presents opportunities for the development of the private international law of Commonwealth countries – including the UK.Focusing on Australia, Canada, New Zealand and Singapore, as well as the UK, an account is given of the relationship between the different systems of private international law in these Commonwealth countries in the period of the UK’s membership of the European Union (EU). Accordingly, consideration is given to the Europeanisation of UK private international law and its resistance in other parts of the Commonwealth. The continuing lead that English adjudication has given to private international law in the Commonwealth and, yet, the greater fragmentation of that law while the UK was in the EU are also discussed. The conclusion considers the need to improve the cross-border enforcement of judgments within the Commonwealth, and the example given in that respect by its federations and the trans-Tasman market. Possible directions that the cross-border enforcement of judgments could take in the Commonwealth are explored.
