The Barcelona Provincial Council approved the Institutional Integrity System along the Anti-Fraud Measures Plan for the Barcelona Provincial Council and the entities within its public sector, and an institutional declaration affirming its highest-level commitment to combating fraud, by resolution of the Plenary Session of 24 February 2022.

The Institutional Integrity System was updated on 23 February 2023. Furthermore, the Anti-Fraud Measures Plan is updated and approved on an annual or biennial basis. Each review of the Plan includes an assessment of the implementation status and progress of the actions carried out during the reporting period.

The Institutional Integrity System integrates the good governance instruments that the Barcelona Provincial Council had already incorporated into its day-to-day operations in compliance with the legislation in force on transparency, together with the instruments and actions arising from the new requirements of the current European regulatory framework—particularly Regulation (EU, Euratom) 2020/2092 on the protection of the Union budget and Regulation (EU) 2021/241 establishing the Recovery and Resilience Facility (RRF)—and the national regulatory framework governing the management system of the Recovery, Transformation and Resilience Plan (RTRP).

As a whole, the Institutional Integrity System consists of eleven elements, structured around the Anti-Fraud Measures Plan (AFMP), constitutes the core instrument of the System and is organised around the four pillars of the anti-fraud cycle: prevention, detection, correction and prosecution.

The Anti-Fraud Measures Plan also includes the validation, formal approval, implementation, and monitoring of the procedure for managing cases involving suspected fraud.
