Arbitration analysis: In a recent judgment of August 29, 2023 (Amsterdam Court of Appeal ), LC Corp, an investor, was authorized to proceed with its intra-EU investment arbitration against Poland, despite the by-now well-known decisions of the European Court of Justice on the incompatibility of arbitration agreements with intra-EU investment protection sources. Poland tried to convince the Dutch courts in various proceedings that the investor should withdraw the investment arbitration commenced against it, first by commencing an injunction procedure and, subsequent, by commencing main proceedings with the same claim.
