As I've said before, if the voter cannot cast his or her ballot in the full knowledge of what is going on in government--whatever the party positions are--then it's a fundamental right terribly diminished.
There's a crisis in the information management of government related to this--that's in one of my reports--but that's curable through administrative means, money, and resources. If anything, this fuels the apathy of citizens. The institutions lose credibility, and to some degree I think Parliament loses credibility if it cannot influence the executives to take needed action--I'm not saying all of the action. But you as parliamentarians lose some credibility when you get this kind of response.
