The ICSID annulment decision in LBKM v. Armenia “stands as the operative outcome” for the purposes of enforcement, and must be given full effect by domestic US courts.
On 14 July 2025, the US District Court for the District of Columbia confirmed the legal effect of an ICSID annulment decision in LBKM LLC v. Republic of Armenia (ICSID Case No. ARB/20/35). The ruling offers rare judicial guidance on the enforceability of annulment decisions under the ICSID Convention.
The underlying arbitration arose under the Armenia–Italy BIT. LBKM’s claim was initially dismissed by the tribunal for lack of jurisdiction, with costs awarded against the investor. However, in 2023, an ICSID ad hoc committee annulled the award, reinstating LBKM’s claim and vacating the costs order. LBKM then applied to confirm the annulment decision in the US, while Armenia objected on the grounds that annulments are not “awards” and are thus unenforceable.
Judge Walton rejected this argument, holding that under the ICSID Convention, “once annulled, the initial award no longer exists for enforcement purposes… The Committee’s ruling stands as the operative outcome.” The Court affirmed that annulment decisions, though not awards per se, are an integral part of the ICSID system and must be given full effect by domestic courts.
This judgment is significant in three ways:
- It clarifies that annulment decisions are binding and enforceable in recognition jurisdictions.
- It reaffirms the self-contained nature of the ICSID system and the limited scope of domestic judicial review.
- It underscores the importance of procedural integrity in ICSID proceedings, as the annulment committee cited serious departures from fundamental rules of procedure.
For both investors and states, LBKM v. Armenia is a timely reminder that ICSID annulment proceedings are not mere formalities—they are decisive instruments of procedural control with concrete legal consequences.
