9.45: Session one: Intra-EU BITS: The struggle between courts and arbitrators 

As the dust from the Achmea decision and Micula saga swirls, courts and arbitrators are taking differing views of limitations on states’ rights and duties under EU law. Where is this leading investor-state disputes? What can we expect going forward?

Among other things, the panel are expected to discuss:

  • The risks for parties and the enforceability of awards;
  • What are the risks for the investor-state dispute settlement system and the continuing friction and the issues of legitimacy and credibility;
  • Should arbitrators take greater account of court practice; and should courts take great account of arbitral practice?

11.30: Session two: The GAR Live symposium

Our espresso version of the popular Tylney Hall format.

The moderators will consider issues such as:

  • Is the UNCITRAL Working Group III going in the right direction?
  • What are the most important issues sovereign states should take into account when deciding whether to enter into investment treaties and negotiating their terms?
  • Will the proposed ICSID rules changes serve their purposes?
  • Which direction is the pendulum moving on a proposed investment court?
  • How have panels performed this year on quantum issues?

12.45: Networking lunch 

14.15: Session three: What will the US-Mexico-Canada agreement mean for NAFTA and investor-state arbitration?

President Trump was faced with much debate on whether the US should revamp or withdraw from NAFTA, and after down-to-the-wire negotiations he was able to produce USMCA. This new agreement retains some of the old provisions in NAFTA. However, it attempts to curtail the ISDS system and, more importantly, reframes NAFTA. 

Questions the panel are expected to discuss include:

  • What are the prospects of USMCA being ratified?
  • What are the main procedural and substantive differences between NAFTA and the USMCA?
  • What is the effect of having a regime without reciprocity within the USMCA?
  • What is the response to investor-state arbitration being unavailable between the US and Canada?
  • Can the Comprehensive and Progressive Trans-Pacific Partnership (TTP-II) fill the ISDS gap in the USMCA with respect to Canadian and Mexican investors?
  • Will environmental or labour critics of NAFTA be happy with the change?

16.00: Session four: The GAR Live debate

In Oxford Union style, we will hear teams of debaters argue in favour of, or against, a motion. A panel of judges will then voice opinions on what has been heard, before choosing which side to support and giving reasons for their decisions.

Motion: “This house believes that the current format of investment treaty awards undermines the legitimacy of an investor-state arbitral dispute settlement”

Questions the panel are expected to discuss are:

  • Does the procedural detail and extensive recitation of arguments hide the crux of the matter from a lay audience and therefore undermine the legitimacy of the decision making to the public?
  • If so, is it too late to change, or can steps be taken to improve the situation?
  • Can arbitral awards be refashioned without adversely affecting the due process rights of the parties?
  • Would it be beneficial to make executive summaries a mandatory feature of investment treaty awards?
  • Is there some other respected institution that could be entrusted with responsibility for making ISDS decisions more accessible and understandable to the public?
