10.00: Session one: International arbitration - bridging or entrenching divides?

International arbitration has evolved as a system for the resolution of disputes between parties from different countries, often operating in different languages, and whose approach to dispute resolution is informed by the perspectives of very different legal systems or cultures.

These differences manifest themselves in parties’ arbitration agreements and the approach they take once a dispute has arisen. Our distinguished panel will explore some of the day-to-day issues that arise for Turkish parties contracting internationally in today’s commercial arbitration landscape, including:

  • Appointing arbitrators: the perspectives of civil law and common law parties and counsel.
  • Evidence: Are the Prague Rules a real alternative to the IBA Rules?
  • Arguing Turkish law claims in the English language.
  • Common law (governing law) arbitrations in civil law seats.
  • The impact of economic sanctions on international arbitration: how do institutions and arbitrators deal with them?
  • The wave of regionalism in the international arbitration world. How do regional arbitration centres compare to the traditional institutions?

14.15: Session two: Investment Arbitration – A safe harbour in turbulent times?

While controversies rage about the legitimacy and future of ISDS in Europe and the Americas and the ISDS Reform agenda picks up speed at UNCITRAL, investment arbitration appears in rude health in Turkey and its environs. BIT and OIC claims continue to proliferate in the region. 

Our distinguished panel will review recent developments and hot topics: 

  • The track record of Turkish investors as claimants.
  • Domestic proceedings: more than a question of jurisdiction or admissibility for parties and Tribunals?
  • The rise of OIC Investment Agreement claims.
  • Corruption pleas: a diversionary tactic or effective shield?
  • Securing third-party funding for an investment claim: the funder’s perspective in 2019.
