CIADI Panel Keeps Lima Metro Line 2 Award on Hold, Denies Claimant’s Guarantee Request

The decision shields Peru from paying over $200 million during annulment proceedings by citing good‑faith conduct plus the risk of prejudice from a parallel review.

Overview

  • The ad hoc annulment committee on November 1 maintained the suspension of enforcement of the CIADI award in Case ARB/17/3 concerning Metro de Lima Línea 2.
  • The committee rejected the concessionaire’s bids to lift the stay or force Peru to post a financial guarantee, finding no risk of nonpayment and affirming the State’s solvency.
  • It noted Peru’s request for annulment filed on March 4, 2025 was not dilatory and reflected serious compliance with international obligations.
  • The panel warned that executing the award now could cause substantial prejudice to Peru and undermine institutional coherence because the same award faces a parallel review.
  • Peru continues to seek annulment through its Special Commission with counsel from Squire Patton Boggs, which has been contracted for S/9.9 million for the defense.
