The Fiscal Affairs Department (FAD) supported the Government of Mauritius through the Ministry of Finance and Economic Development (MoFED) to undertake a diagnostic review of the existing legal framework for Public Financial Management (PFM) and supporting fiscal institutions with a view to advise on design options and implementation requirements for fiscal responsibility legislation (FRL). The technical assistance report proposes a comprehensive FRL framework that incorporates fiscal responsibility principles, numerical and procedural fiscal rules, mandates the development of a detailed medium-term fiscal framework (MTFF), and establishes robust transparency requirements and corrective mechanisms to facilitate effective implementation. Reinforcement or reform of several priority fiscal institutions, such as macro-fiscal forecasting, MTFF, budget preparation process, fiscal risk management and fiscal reporting is required to support effective implementation of the FRL.
