Why Whistleblowing & Investigations Processes Matter
Whistleblowing
The EU Whistleblowing Directive requires all public and private organizations with 50+ workers to establish whistleblowing hotlines and meet minimum standards for handling reports. Because the Directive had to be implemented into national laws, the resulting rules are not fully harmonized and may differ across Member States.
Welldesigned whistleblowing systems are in any case essential tools for protecting your company’s integrity, reputation, and longterm resilience. When concerns are raised — whether by employees, vendors, customers, or other stakeholders — and handled properly, your company can address issues early, keep matters contained, and demonstrate accountability before regulators or the media become involved.
A structured, compliant approach not only reduces legal and reputational risk. It also strengthens trust across your company and supports a healthier, more transparent business culture. It is, ultimately, a smart investment in your company’s public reputation.
We at Liberius see dispute resolution as more than just a legal service; we see it as a business tool. We assist our clients in avoiding conflicts whenever possible, effectively resolving them when they do arise, and successfully litigating when they cannot be avoided. Our senior-only attorneys offer lucid, resolute advocacy in court, arbitration, and negotiation, always keeping the client’s business interests front and center.

Investigations
Regulatory and law enforcement investigations have become more frequent and more complex. Stronger investigative powers, higher potential fines, and increased cooperation among regulators across jurisdictions mean that companies face heightened scrutiny.
Internal investigations now often span multiple countries, legal systems, and regulatory bodies. For companies, these matters can create significant risks — including litigation exposure, reputational harm, data protection challenges, and potential regulatory or criminal liability. Being prepared and able to respond quickly and flexibly is essential.
Liberius offers a national, pan-European or global approach to internal investigations, integrated into a single, coordinated service. We combine international and local expertise and assemble tailored teams of specialists depending on your needs. This may include trial lawyers, employment lawyers, former prosecutors, privacy experts, competition and ESG specialists, cybersecurity professionals, forensic specialists, and others.

FAQs – What Clients Ask Us
Does every company in the EU require a whistleblowing hotline?
Under the EU Whistleblowing Directive, any private and public companies with 50 or more workers must establish internal reporting channels and accept reports about breaches of EU law. So not every organisation is legally required to operate a whistleblowing hotline. However, every organisation is strongly advised to provide a safe and reliable way for people to raise concerns. A hotline is simply one of the most effective and compliant mechanisms to do so, particularly as regulatory expectations continue to rise.
Do we really need a whistleblowing system if we already have HR and compliance processes?
HR and compliance teams play an important role, but they are not a substitute for a dedicated whistleblowing channel. A structured system ensures independence, confidentiality, and proper handling of reports in compliance with applicable legal requirements of each EU Member State.
What happens if we don’t have a process for handling complaints and regulatory queries?
Without a clear process, issues can escalate quickly: complaints may be mishandled, information may leak, and regulators may view the company as unprepared and noncompliant. This can trigger regulatory investigations, attract negative media scrutiny, lead to fines, and create a range of other legal and reputational consequences. A simple, well‑defined process helps prevent small problems from becoming major risks.
Are there specific legal requirements for whistleblowing channels?
Yes. Many jurisdictions require companies to follow specific rules on how reports are received, assessed, and documented. The exact requirements may vary per country, but the expectation of a structured system is now standard.
Are there legal rules on how internal investigations must be conducted?
Yes. The rules may vary per country where the investigation takes place, and sometimes even by the type of allegation involved. Understanding which jurisdictions are in scope — and what their requirements are — is essential. A noncompliant investigation can create additional legal exposure and undermine the credibility of the findings.
Why is an investigations protocol important?
A protocol ensures that every investigation is handled consistently, lawfully, and efficiently. It defines roles, timelines, documentation standards, and escalation paths, reducing risk, strengthening the credibility of outcomes, and making the process easier for everyone involved.
How do we make sure investigations stay confidential and controlled?
Confidentiality depends on clear governance: defined access rights, secure information handling, and a disciplined approach to communication. A structured process keeps sensitive matters contained and reduces the risk of leaks, mistakes or misunderstandings.
Can you help us if a regulator or authority is already involved?
Absolutely. We support clients at every stage — from early internal reviews to responding to regulatory inquiries. Even if an authority is already engaged, a strategic, well‑managed approach can significantly reduce exposure and protect the organization.
Who should handle an internal investigation — HR, Legal, Compliance, or someone external?
It depends on the nature of the issue and the overall maturity of your organisation’s compliance framework. Routine matters may be handled internally, but sensitive, high‑risk, or senior‑level cases often require independent oversight or external support to ensure impartiality and credibility.
How quickly do we need to react when a report or complaint comes in?
Prompt action is essential. Regulators expect resolution within given deadlines, and delays can increase risk, allow issues to escalate, or undermine trust in the process. A quick, structured first response sets the tone for the entire investigation.
