I think it would be very worth while considering that. It's not within my realm, of course, but it is a problem, and if it becomes an increasing problem.... I struggled with the Thibault case for a long time, putting out the report. As you know, I found technically that he had contravened the code in the sense that it was a private interest. Of course the reaction of the House was to amend the code slightly.
I personally feel that disclosure is the important thing. The issue there was disclosure and recusal in the House. Personally, I feel that disclosure is always a good idea. Recusal is not necessarily always a good idea. That's my take on this Thibault situation.
I would have no problem contemplating there being some rules in legislation to circumscribe libel suits with respect to MPs.
