As I've said before, independent reporting is at the heart of the assessment process. Without all that independent reporting process, you would have to have serious worries, particularly in the kind of scenario where there seems to be a lot of contestation about the actual kinds of human rights impacts.
So yes, independence is going to be a vital part of the process, and also, as I've said, worries about the frequency and scope, and finally the results in terms of the recommendations.
In terms of a report simply being laid before Parliament, your parliamentary processes may be somewhat different from mine, so please put it into your own political context, but in my past experience, the danger is that a report by Parliament is not necessarily acted upon unless there is a procedure specified, in whatever agreement or regulations in advance, about the kinds of actions that could be taken. That would be the final concern I would have regarding the current process, along with the other ones I've spoken about.
