Dual Criminality in Crypto Crimes

Dual criminality is a legal principle requiring that an act must be considered a crime in both the requesting and the requested jurisdiction for extradition or legal assistance to occur. In the context of crypto crimes, this can be problematic because different countries have vastly different definitions of digital assets.

For instance, an activity might be classified as securities fraud in one country but remain unregulated or legal in another. If the requested state does not recognize the activity as a crime, it may refuse to provide evidence or extradite the suspect, creating a significant loophole.

This requirement necessitates that prosecutors carefully build their cases to demonstrate that the underlying conduct, such as theft or fraud, is universally recognized as illegal, even if the specific label for the digital asset varies. As international law evolves to address the unique nature of crypto, some treaties are being updated to lower the threshold for dual criminality.

This is essential to prevent suspects from finding refuge in countries that have not yet updated their laws to include digital asset offenses. Understanding this principle is crucial for any legal strategy involving international cooperation in crypto-related matters.

It remains a fundamental hurdle that reflects the slow pace of legal adaptation compared to the rapid innovation of blockchain technology.
