Mutual legal assistance is to assist prosecutors in different countries to access evidence for criminal prosecutions. There's a wide variety of things that could be sought to be of assistance in pursuing a prosecution. It could be witness testimony; it could be documentary information. A lot of the time it involves Internet service provider information, such as telephone records, texting records and email records. That's increasingly important in criminal prosecutions. It may be access to a particular item—a murder weapon, for example—that could be transferred across the border pursuant to a mutual legal assistance request.
Those are the general types of things. It could be anything, basically, that is relevant as a piece of evidence in a prosecution.
