9.45: Session one: investment arbitration and the climate emergency

Climate change and the environment are never far from the headlines in 2020 but how will this affect investment arbitration. Our esteemed panel will examine recent developments and trends including:

  • Should investors expect host states to take measures affecting their investments in order to preserve a healthy environment?
  • The challenge of quantifying damages in environmental cases;
  • Will environmental regulations lead to mass claims?
  • Should provisions be included to address environmental issues and protect investors against environmental changes?

11.00: Coffee break 

11.30: Session two: The year in review

The return of a GAR Live favourite, our panel will examine all of the latest developments in international investment arbitration, including:

  • The state of enforcement and contradictory decisions in solar awards against Spain;
  • The latest Micula developments;
  • EU intervention in enforcement proceedings;
  • 1782 discovery requests and investment arbitration;

12.45: Networking lunch

14.00: Fireside chat

14.30: Session three: Settling investment disputes – more achievable than commonly thought?

Received wisdom says that states find it almost impossible to settle disputes – even when doing so would make a lot of sense. It is easier to “leave it to the next guy” than to take a politically unpopular decision. But does the received wisdom still hold true? A series of anecdotes have reached the GAR offices in which states have been willing and indeed able to reach a rational conclusion with investors – before an arbitrator ordered them to. In this session our panel will examine how some counsel have found ways around this traditional problem.

  • Difficulties for the state to settle such as transparency, domestic law and political hurdles;
  • First hand accounts from counsel who have persuaded states to settle cases early;
  • Cases where this has been seen such as Boonyanit.

15.45: Coffee break

16.15: Session four: The GAR Live Debate – This house believes that big tech will embrace investment arbitration

With large technology companies showing signs of threatening claims under investment treaties. Is it time to consider the practicalities such disputes would present? In Oxford Union style, we will hear teams of debaters argue in favour of, or against, the motion. A panel of judges will then voice their opinions on what has been heard, before choosing which side to support and giving reasons for their decisions.
