About Elliott:
Elliott specialises in criminal and regulatory matters, including health and safety, business crime, transport regulatory and sports regulation.
When your organisation faces suspicion of wrongdoing, it is vital to take swift and decisive action. The benefits of conducting an internal investigation are numerous, and include understanding the issues in greater detail, insulating management and the board from stakeholder criticism and loss of confidence, and giving the best possible chance of reducing regulatory risk exposure further. If the investigation is conducted appropriately, it may also attract legal professional privilege, which shields an investigation from onward disclosure.
Our team of expert internal investigation solicitors is dedicated to helping businesses navigate complex regulatory and criminal risks with confidence.

We are able to mobilise a core investigatory team quickly to assist an organisation at a time of crisis. We can advise on the scope of the investigation quickly and seamlessly, and engage with other members of core teams and third parties to support the investigation.
Many organisations elect for Weightmans to conduct their internal investigations as we can provide unravelled and independent expertise. The involvement of external lawyers may enable the investigation to be undertaken under legal professional privilege which can protect the investigation and the materials produced as part of the investigation from disclosure to third parties.
We understand that when a crisis begins to dissipate, organisations want to ensure that business is disrupted to a minimum. We work with and structure internal investigations in such a way that we conduct investigations discreetly, advise organisations pragmatically throughout the investigation, and produce clear findings and recommendations to instigate positive change within an organisation, whilst allowing an organisation to return to business as usual.
Clients often turn to us to review their operations after a period of time has elapsed to consider whether improvements have been properly and sustainably implemented.
For some internal investigations, a parallel law enforcement/regulatory agency investigation will be taking place simultaneously. We have expertise in managing the relationship with the appropriate authorities given our wide-ranging expertise, with the primary objective of protecting an organisation’s best interests.

An internal investigation is an investigation conducted by an organisation, typically after wrongdoing is discovered within that organisation. That investigation is internal in that the organisation is managing, conducting or otherwise instructing a third party to undertake that investigation on their behalf. A parallel external investigation may be taking place, by law enforcement or another investigative agency involving the same wrongdoing.
There are numerous benefits, which include:
Any regulatory risk or other concern / suspicion of wrongdoing within an organisation. This may include very obvious issues (fraud, theft, workplace fatality), or more covert (whistleblowing report, a near-miss incident, a customer complaint, or an event which may present a significant risk to the organisation’s reputation).
An internal investigation may also be triggered in an organisation where they have been the victim of crime, such as a fraud. An internal investigation is often undertaken with a view of considering civil recovery, onward reporting to law enforcement or a private prosecution.
We would recommend that internal investigations are conducted by experienced investigators, with close supervision and control. Often organisations would like an independent investigation to be conducted by a law firm or equivalent for impartiality reasons and for the investigation to attract legal professional privilege (LPP), which may protect the documents created by an internal investigation being disclosed to third parties. Weightmans is ideally suited to assist organisations conduct their internal investigations, due to our deeply engrained expertise in a wide number of regulatory risks and our experience of conducting legally privileged complex internal investigations to buy organisations critical time in understanding the issues before third parties do.
An internal investigation often begins shortly after the investigation trigger such as the discovery of wrongdoing. Often an organisation will seek independent legal advice at this stage. The investigation needs to be suitably scoped, and key teams identified who will work as part of the internal investigation team. Governance arrangements need to be implemented as part of the scoping exercise. This should be codified into a plan or terms of reference. Once an investigation is scoped, the investigation can commence which will usually involve collating and reviewing documentary evidence, undertaking interviews with investigation subjects, and producing an investigation report.
The length of time to complete an internal investigation varies considerably. In our experience, very simple investigations can take a number of weeks, whereas complex multi-faceted investigations can take several months to complete.
The final stage of an internal investigation is the production of an investigative report/advice. This may include a number of recommendations to prevent or mitigate against the risk occurring in the future. Weightmans works with organisations, not only throughout the internal investigation lifecycle, but assisting the organisation with the adoption of recommendations.
