Sure. If you look at some of the jurisprudence, such as Justice Moldaver's majority opinion in Kokopenace, it's pretty clear that Justice Moldaver thinks that random selection is the most important principle, whereas Justice Cromwell, in the dissent, with Chief Justice McLachlin, thinks that the significant under-representation of indigenous people on juries presents a really pressing problem. So instead of depending on whether I get a Justice Moldaver disciple or a Justice Cromwell disciple, I think Parliament should be clear about why it is adding this ground, and it shouldn't simply leave it to judicial discretion.
Confidence in the administration of justice is in the eyes of the beholder, and if this is about preventing another Gerald Stanley case, I think Parliament should be clear about that.
