A great many new developments needed to be considered for the fourth edition of this popular book on international arbitration. To name only a few:
- The recent revision of Chapter 12 of the Swiss PILA which will enter into force on 1st January 2021, and in the drafting of which both authors have been heavily involved;
- the revision of the Legal Framework of the Court of Arbitration for Sports in Lausanne;
- the inclusion of more than 80 new decisions of the Federal Supreme Court, many of them sending important messages to the arbitration community;
- the most recent revisions of the numerous institutional rules covered by this book, such as of the ICC, LCIA, DIS, SCC, SIAC, HKIA, and VIAC.
