GreenX Metals Limited (formerly Prairie Mining Limited) v. Republic of Poland (I)
UNCITRAL · Investment (ICSID and treaty) · England and Wales (BIT), Singapore (ECT) · 8 Oct 2024
Why it matters
This case is a landmark investor-state arbitration where the tribunal awarded substantial compensation under two separate treaties for the same investment, while ensuring no double recovery. It highlights the application of the Energy Charter Treaty and a bilateral investment treaty in parallel, and the high threshold for set-aside in England and Singapore. The award demonstrates the effectiveness of UNCITRAL arbitration in protecting foreign investors against state measures.
Summary
GreenX Metals Limited (formerly Prairie Mining Limited) brought arbitration claims against the Republic of Poland under the Australia-Poland Bilateral Investment Treaty (BIT) and the Energy Charter Treaty (ECT). The dispute arose from Poland's actions affecting GreenX's coal mining projects, Jan Karski and Dębieńsko. The tribunal, constituted under UNCITRAL Rules, unanimously held that Poland breached its treaty obligations regarding the Jan Karski project, awarding approximately £252 million under the BIT and £183 million under the ECT, with interest compounded at SONIA +1% from 31 December 2019. However, the claim for the Dębieńsko project was dismissed. To prevent double recovery, any payment under one award is set off against the other. Each party bears its own costs. The awards are final and binding, with no appeal on merits; set-aside is possible only on limited grounds in the courts of England and Wales (for the BIT award) or Singapore (for the ECT award). The case underscores the parallel application of investment treaties and the importance of the seat of arbitration for post-award remedies.
