Switzerland Follows EU in Blocking Russian ISDS Claims

Switzerland has aligned with the European Union by introducing measures to counter what it calls “illegitimate” investment treaty claims initiated by Russian entities in connection with sanctions. This decision comes just a month after Switzerland announced that Russian investors would no longer be granted protection under the Energy Charter Treaty.

Switzerland has introduced measures to combat “illegitimate” investment treaty claims by Russian parties relating to sanctions.

The new regulations signal Switzerland’s continued effort to coordinate with EU policy responses and reinforce the broader international stance on restricting Russian access to international arbitration protections tied to sanctions disputes.

Background

The move reflects a growing trend among Western jurisdictions to limit legal recourse for sanctioned entities seeking compensation or arbitration relief under previous bilateral or multilateral investment treaties.

Context

Switzerland joins the EU’s coordinated action against Russian ISDS claims.
The Energy Charter Treaty protections for Russian investors were withdrawn earlier this year.
This marks increased synchronization between Swiss and EU legal measures on sanctions-related arbitration.

Author’s summary: Switzerland strengthens its cooperation with EU sanctions policy by denying Russian investors arbitration protections and blocking related ISDS claims.
