This webinar formed part of the Australian Arbitration Week 2021 program hosted by ACICA.

What does the seminar cover?

It explore the situations where an arbitrator might be said to have performed its office so as to be (wholly or as to particular aspects of the referred dispute) functus officio. Whether an arbitrator is functus officio is important for determining the question of the continuing arbitrator’s jurisdiction, which is fundamental to the validity and enforceability of a subsequent arbitral award.

The speakers traverse a range of issues on this topic including:

  • When an arbitrator is functus officio
  • The weight that courts give to an arbitral tribunal’s reasons for determining its jurisdiction
  • Whether courts can remit a matter to an arbitral tribunal after an award has been set aside

Who should watch?

The principles discussed will be relevant to all commercial litigators, as well as arbitration and alternative dispute resolution pracitioners.
