On 17 August 2020 Switzerland found itself on the responding side of an arbitration claim at the International Centre for Settlement of Investment Disputes (ICSID) in Washington D.C. This claim was originally filed on 29 May 2020, when a legal entity domiciled in the Seychelles islands and controlled by a Swiss citizen filed an arbitration claim against Switzerland at the ICSID. The Seychelles based legal entity relied on the provisions of the bilateral investment protection agreement between Switzerland and Hungary (the Swiss-Hungarian BIT) to file this claim. The legal entity has claimed to initiate these arbitration proceedings on behalf of three Italian nationals who supposedly suffered losses due to the urgent federal decree on a temporary prohibition of the resale of non-agricultural land passed by the Swiss Parliament in 1989.
