What best defines mutual legal assistance (MLAT) and which two forms of cooperation are typical under MLATs?

• A. Unilateral measures for domestic enforcement with no cross-border element; typical forms: domestic warrant issuance and local asset seizure.
• B. A legal framework for cross-border cooperation in criminal investigations; typical forms: gathering evidence (documents, witness testimony) and extradition requests.
• C. A treaty for military alliances; typical forms: extradition and defense pacts.
• D. A data-sharing protocol for civil cases; typical forms: filing civil complaints and sharing case notes.

Answer: (B)

Mutual legal assistance is a framework that enables countries to help each other with criminal investigations and prosecutions across borders. Under MLATs, the typical forms of cooperation are gathering evidence located in other jurisdictions—such as documents, records, and witness testimony—and extradition requests, where a suspect or convicted person is surrendered to face trial or serve a sentence in the requesting country. This combination reflects how cross-border criminal cases are often solved: you need access to foreign-held evidence and a mechanism to move suspects between countries for justice. The other choices don’t fit because they describe actions that are unilateral and domestic, military alliances, or civil data-sharing, none of which capture the cross-border criminal assistance MLATs are built to provide.
