At the NJI, we have a number of lawyers on staff. They're responsible for working with the judges to plan the programming, and they do a great deal of research. When we look at a course, they will consult with academics, do their own independent research, and then bring to the judges some of the information, ideas, and new work that's out there to help design the program.
In terms of education for judges' research assistants, and so on, I can only speak to my court. They are all provincial employees, so the training would be dealt with through the province.
