“Twilight Issues” in International Arbitration

24 April 2018

Time: 5:00am - 8:30pm
Venue: Centre for Commercial Law Studies, Queen Mary University of London, 67-69 Lincoln's Inn Fields, London WC2A 3JB UK

SIA and CICIA logosThis seminar on “Twilight Issues” in International Arbitration is organised by the School of International Arbitration, Queen Mary University of London and Columbia Law School.

This seminar discusses important non-merits issues that commonly arise in arbitral proceedings for which tribunals and counsel find little or no guidance in either the arbitration agreement, the institutional rules, or the lex arbitri. These “Twilight Issues” include:

  • arbitrability of the dispute
  • arbitration agreement and non-signatories
  • conditions precedent to arbitration
  • interim relief
  • waiver of right to arbitrate
  • anti-suit injunctions
  • privilege
  • iura novit curia
  • statutes of limitation
  • res judicata
  • rates of interest
  • cost allocation
  • sanctioning party conduct.

In addressing Twilight Issues, arbitral tribunals and counsel may resort to, among other things, the application of national law (including law of the contract, law applied by the courts of the place of arbitration, law of the place of probable enforcement, law of the country with the closest connection) or an international standard or no particular norm at all. The seminar explores how tribunals and counsel best proceed facing these questions.

The seminar is co-chaired by Professor George A. Bermann (Jean Monnet Professor of EU Law and Director, Center for International Commercial and Investment Arbitration, Columbia Law School) and Professor Maxi Scherer (School of International Arbitration, Queen Mary University of London, Chair in International Arbitration and Energy Law).
