Whistleblowing: Confidentiality, Data Protection and Record-Keeping

WB-Art.16
Duty of confidentiality

The identity of the reporting person shall not be disclosed, without their explicit consent, to anyone beyond the authorised staff competent to receive or follow up on reports, except where this is a necessary and proportionate obligation under Union or national law in the context of investigations or judicial proceedings (with prior information to the reporting person where possible).

Artefacts an auditor will ask for

  • Process for informing the reporter before any required disclosure
Where this commonly fails

  • Disclosure without the legal-obligation basis
WB-Art.17
Processing of personal data

Any processing of personal data carried out pursuant to the Directive, including the exchange or transmission of personal data, shall be carried out in accordance with Regulation (EU) 2016/679 (GDPR) and Directive (EU) 2016/680; personal data manifestly not relevant to a specific report shall not be collected or, if accidentally collected, deleted without undue delay.

Artefacts an auditor will ask for

Where this commonly fails
  • External channel without integrity/confidentiality safeguards
WB-Art.13

Where this commonly fails
  • No periodic review of procedures

Whistleblowing: Internal Reporting Channels

WB-Art.7
Reporting through internal reporting channels

Member States shall encourage reporting through internal channels before external reporting where the breach can be addressed effectively internally and the reporting person considers there is no risk of retaliation; entities shall provide information on the use of internal channels.

Artefacts an auditor will ask for

Where this commonly fails
  • No guidance steering reporters to internal channels first
WB-Art.8
Obligation to establish internal reporting channels

Artefacts an auditor will ask for
  • Established internal reporting channel(s) (e.g. hotline, portal, in-person)
  • Confidentiality controls restricting access to authorised staff
Where this commonly fails
  • No internal channel despite 50+ workers
  • Channel that exposes reporter identity to unauthorised staff

Where this commonly fails
  • Employment terms or NDAs purporting to waive reporting rights
WB-Art.25
More favourable treatment and non-regression clause

Member States may introduce or retain provisions more favourable to reporting persons than those in the Directive, and implementation shall not constitute grounds for reducing the level of protection already afforded.

Artefacts an auditor will ask for
  • Confirmation that national/organisational measures do not lower pre-existing protection
Where this commonly fails
  • Using transposition to reduce existing whistleblower protections

Whistleblowing: Protection Measures

WB-Art.19

  • Access to free information/advice and assistance for reporters
Where this commonly fails
  • No support or advice route for reporters
WB-Art.21
Measures for protection against retaliation

Protected persons shall not be considered to have breached restrictions on disclosure and shall not incur liability for reporting or public disclosure made in accordance with the Directive; in proceedings concerning detriment suffered, where the reporter shows they reported and suffered a detriment, it shall be presumed the detriment was retaliation and the burden shifts to the person who took the measure to prove it was based on duly justified grounds.

Artefacts an auditor will ask for
  • Process implementing the reversal of the burden of proof and liability exemptions
Where this commonly fails
  • Placing the burden of proof on the reporter
  • Treating protected disclosures as a breach of confidentiality
WB-Art.22
Measures for the protection of persons concerned

Persons concerned (those referred to in a report) shall fully enjoy the right to an effective remedy and to a fair trial, the presumption of innocence and rights of defence, including the right to be heard and to access their file; their identity shall be protected while investigations are ongoing.

Artefacts an auditor will ask for

Where this commonly fails
  • No safeguards for the rights of persons named in a report

Whistleblowing: Public Disclosures

WB-Art.15
Public disclosures

A person who makes a public disclosure qualifies for protection where they first reported internally and externally (or directly externally) without appropriate action being taken within the prescribed timeframe, or where they have reasonable grounds to believe the breach may present an imminent or manifest danger to the public interest, or that external reporting risks retaliation or is unlikely to be effectively addressed.

Artefacts an auditor will ask for
  • Policy describing the conditions under which public disclosure attracts protection
Where this commonly fails
  • Denying protection to public disclosures that meet the Article 15 conditions

Whistleblowing: Scope and Conditions for Protection

WB-Art.4
Personal scope

The Directive applies to reporting persons working in the private or public sector who acquired information on breaches in a work-related context, including workers, self-employed persons, shareholders, members of administrative/management bodies, volunteers, paid/unpaid trainees, and persons working under the supervision of contractors, subcontractors and suppliers; it also covers facilitators, third persons connected to the reporting person, and legal entities the reporting person is connected with.

Artefacts an auditor will ask for
  • Mapping of categories of persons eligible for protection in the organisation's whistleblowing policy
Where this commonly fails
  • Policy limiting protection to direct employees only
WB-Art.5
Definitions

Defines the key terms (breaches, information on breaches, report, internal/external reporting, public disclosure, reporting person, facilitator, work-related context, person concerned, retaliation, follow-up, feedback, competent authority).

Artefacts an auditor will ask for
  • Consistent use of the directive definitions in the whistleblowing policy and procedures
Where this commonly fails
  • Ambiguous or absent definitions of report, retaliation, follow-up
WB-Art.6
Conditions for protection of reporting persons

Artefacts an auditor will ask for
  • Criteria in the policy for when a reporter qualifies for protection (reasonable-grounds and scope test)
Where this commonly fails
  • Conditioning protection on the report being ultimately proven correct
  • Requiring proof of motive
