What is the Independent Whistleblower Protection Authority (A.I.P.I.) and how does it affect your company?
The Independent Authority for the Protection of Whistleblowers (A.I.P.I.) is a key body created by Law 2/2023 of 20 February in Spain. Its purpose is to ensure the protection of whistleblowers and to fight corruption effectively.
This figure represents a significant change in the corporate compliance landscape. With its entry into force on September 1, 2025, all companies bound by the law must prepare in advance.
Main functions of the A.I.P.I.
The responsibilities of this new body are wide-ranging and have serious legal implications for companies:
🔍 Supervision and control
It is responsible for verifying that companies and public entities comply with Law 2/2023, especially with regard to the internal complaints channel.
⚖️ Sanctioning power
It has the authority to impose financial penalties, some of them very high, in the event of noncompliance.
🛡️ Whistleblower protection
Its main objective is to ensure that the whistleblower does not suffer retaliation. Whistleblower protection is mandatory and enforceable.
When does the A.I.P.I. become effective?
