# Whistleblower law in Slovenia

Slovenia implemented Directive (EU) 2019/1937 through the **Zakon o zaščiti prijaviteljev (ZZPri)**, in force since **22 February 2023**. Slovenia gives a visible role to the **Commission for the Prevention of Corruption (KPK)** for protection and reporting oversight.

## Applicable law

- [ZZPri — official text in Uradni list](https://www.uradni-list.si/glasilo-uradni-list-rs/vsebina/2023-01-0471)
- [KPK — protection of reporting persons](https://www.kpk-rs.si/en/commissions-activities/protection-of-reporting-persons)

## Who must establish an internal channel

Employers with **at least 50 workers** must establish an internal reporting channel under the Slovenian act.

## External reporting authority

The central official institution in the Slovenian system is the [Commission for the Prevention of Corruption (KPK)](https://www.kpk-rs.si/en/commissions-activities/protection-of-reporting-persons), which provides guidance on protection measures and reporting-person status.

## Data protection authority

For GDPR complaints about whistleblower data handling, the relevant authority is the [Information Commissioner of the Republic of Slovenia](https://www.ip-rs.si/en/) and its [complaint filing page](https://www.ip-rs.si/varstvo-osebnih-podatkov/pravice-posameznika/vlo%C5%BEitev-prijave).

## Key compliance points

- The KPK can issue a certificate of eligibility for protection, which makes the Slovenian framework more institutionally concrete than a generic hotline model.
- Slovenia also expects annual reporting statistics from obliged persons and external reporting authorities to the KPK.
- Internal procedures should make clear that the statutory system is for legally defined reporting-person protection, not just any workplace complaint.
