In each case, when they got to the point of establishing a pilot project, there were reports a year or so after the first year of operations. That was a report to Parliament, around which there was a determination made as to whether they would go forward, and in some cases what changes or modifications they would make.
In terms of the span of time, a committee looking at this would need at least several months—there's a ton of information out on this—to put together an initial set of proposals. They would need to get it out for input and consultation—that's perhaps another half year—and then try an experimental or pilot project, all broadly within the framework of one Parliament. Then, perhaps at the end of that Parliament or some time shortly after, there would be a report on its utility and its usefulness to Parliament, and only after that—probably in the Parliament after that—an adoption, if Parliament chose to make it a permanent part of the institution.
