Sanctions internal investigations

An internal investigation is a structured process by which an organisation establishes the facts relating to a specific allegation or concern and assesses potential breaches of applicable laws, regulations, or internal policies. Internal investigations related to breaches of international sanctions (“Sanctions Internal Investigations”) conducted by organisations’ own initiative are becoming a core element of compliance frameworks. As enforcement intensifies²See, inter alia and in the EU context, European Sanctions Enforcement - performance league tables (2017-2024) October 25, 2024by Mark Handley. As of October 2024, more than 4000 enforcement actions had been initiated in all 27 EU Member States., regulators are likely to place greater reliance on companies to proactively detect, investigate, and remediate potential breaches in a structured manner, in line with internal investigation practices developed in other areas of regulatory compliance.
Whilst building on well-established principles in other practice areas, notably fraud and anti-corruption investigations, sanctions investigations present distinct challenges: violations may not be immediately apparent, often involving complex third-party relationships, opaque ownership structures, and fragmented multi-jurisdictional landscape that complicates voluntary self-disclosure strategy.

Practical implications for organisations are threefold:

* Detection should prioritise proactive controls, rigorous screening and internal audit over reactive whistleblowing channels alone.
* Investigation conduct will generally focus on systems and controls rather than individual intent, reflecting the strict liability nature of many sanctions offences in jurisdictions such as the United States (“US”) and the United Kingdom (“UK”).
* Voluntary self-disclosure, viewed favourably in most jurisdictions and even financially encouraged in jurisdictions such as the US and the UK, requires careful jurisdictional mapping and strategic sequencing with prompt, well-documented disclosure consistently yielding the most favourable enforcement outcomes.
