AS Windoor has filed for international arbitration proceedings at ICSID in Washington, D.C., seeking more than 20 million euros from the Republic of Kazakhstan

AS Windoor (“Windoor”), one of the largest manufacturers of glass and aluminium facades in Estonia has filed for international arbitration against the Republic of Kazakhstan for breach of the treaty between the Government of the Republic of Estonia and the Government of the Republic of Kazakhstan on the promotion and reciprocal protection of investments (“the Treaty”).

These breaches relate to various administrative and law enforcement actions taken by Kazakhstani authorities which have obstructed Windoor’s enforcement of an arbitral award issued in 2015 by the Stockholm Chamber of Commerce. That award ordered a Kazakhstani state enterprise to pay Windoor around 23 million euros in a dispute concerning its investment in the construction of an international business and conference centre in Astana.

For over two years after obtaining the award, Windoor pursued various legal and procedural avenues in the Republic of Kazakhstan to enforce the arbitration award. In February and October 2016, the company notified the Republic of Kazakhstan of its intention to request international arbitration if the latter failed to fulfil its obligations under the Treaty. The Republic of Kazakhstan has not fulfilled its obligations to date.

On 14 September 2018, Windoor filed a Request for Arbitration with the International Centre for the Settlement of Investment Disputes, which is part of the World Bank Group in Washington D.C. The company is represented in these proceedings by Jones Day (Washington & London) and Sorainen (Tallinn).

ICSID is an international arbitration body that supports the resolution of legal disputes between international investors and countries. ICSID is a part of the World Bank Group with headquarters based in Washington, D.C., United States of America. At present 154 countries, including the Republic of Kazakhstan, are its contracting members, have ratified the ICSID Convention and committed to enforce and uphold its arbitral awards.

Windoor's case is the first proceeding involving an Estonian company and a foreign country in the organization that has been operating since 1966, the full member of which the Republic of Estonia is since July 1992.
