Overview
- The arbitral partial award requires the Municipalidad Metropolitana de Lima to reimburse US$724,099.28, equal to 50% of arbitration costs, a decision reported on September 24, 2026.
- The tribunal found that the city’s January 2023 unilateral termination breached clause 17.7 of the concession and noted the decision was taken without a legal commission report, a cost‑benefit analysis, or efforts to negotiate with the concessionaire.
- The award held the municipality partially liable for failing to deliver land for the Ramiro Prialé stretch and said a separate calculation of partial compensation will be set in a later stage of the arbitration.
- Three major monetary claims by Rutas de Lima — totalling roughly US$97.6 million for inflation adjustments, 'puntos de fuga', and COVID/peaje rebalancing — were unanimously rejected by the tribunal.
- The case was heard under UNCITRAL rules (PCA Case No. 2023-34), produced a majority award with one partly dissenting arbitrator, and may prompt closer municipal compliance with procedural reports and negotiation before contract termination.
