International arbitration definition

What does International arbitration mean? International arbitration describes an arbitration with cross‑border elements, typically where the parties are in different states, the agreed seat or place of performance is abroad, foreign law governs, or enforcement will be against overseas assets. In practice it refers to international commercial arbitration under an arbitration agreement. In England & Wales, Scotland and Northern Ireland it is a descriptive term rather than a statutory category; neither the Arbitration Act 1996 nor the Arbitration (Scotland) Act 2010 defines it. In Ireland, the Arbitration Act 2010 gives UNCITRAL Model Law force of law; Article 1(3) sets out when an arbitration is “international”...

Ethical standards for England and Wales-qualified counsel in international arbitration: regulators’ codes, seat laws, tribunal powers, party-agreed guidelines and institutional rules

Practice notes

Which ethical standards govern English and Welsh practitioners (using English and England for brevity) engaged in international arbitration will vary with the features of the arbitration, and the context in which they are retained to act within such arbitration.

The most important factors for practitioners to consider are the following:

  • the ethical requirements of their professional regulator
  • the ethical duties for lawyers and any pertinent laws of the seat’s jurisdiction, or of the place where they undertake tasks (for example, taking witness statements) connected to an arbitration seated elsewhere in relation to that work
  • any rules or guidance the parties have agreed will apply between them
  • any provisions set by a relevant arbitral institution or organisation
  • measures adopted by tribunals exercising express or implied powers to control and manage the conduct of proceedings

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
