A few years ago there was that thing where an MP used parliamentary privilege for good in that some really aggressive law firm (I think Carter-Ruck) had been retained by an oil company that had pumped loads of deadly sewage on to an African village (or something similar, I forget the precise details) and basically Carter-Ruck had got one of those so-called super-injunctions which, if I understand correctly is an injunction that bans someone from saying something, but also bans them from saying that they were banned from saying it - it ultimately prevents them from alluding to it and hinting and so on and is used to completely bury the terrible truth. It means that not only is that truth hidden, but the public don't even know that there is something that has been hidden. Anyway, an MP used parliamentary privilege to discuss this oil firm and the terrible things they had done, knowing that Carter-Ruck could not go after him for what he said in parliament. They tried to fight back by sending preemptive threats to newspapers saying that if they reported what was said then they would be at risk of being sued but the papers then reported that and it all blew up in their faces and the very thing that they had desperately tried to keep totally secret was front page news for a week. Ha, fuckers!
Anyway, like I said, that was parliamentary privilege used for good. It now seems that we are seeing the opposite of that - the Tories are exploiting the fact that they can't be sued for anything they say in parliament - along with the fact that parliament (in the form of the speaker Lindsey Hoyle) has made it very clear it will not make any effort to prevent them from lying - to simply slander the opposition. Maybe people have slandered people in the house before, inadvertently or spitefully, but this seems to be the first time that a party appears to have looked at the rules as they are and said "Hey guys, let's slander the opposition, the rules will protect us" - it's taken ten years or so from the above story for the penny to drop on this one. You would hope that if we have a situation where the rules protect the liar and slanderer and we can all see that happening, then maybe it will finally lead to an overhaul of the rules which are clearly not fit for purpose - the alternative is that it descends into even more of a farce than we've seen over the last few years...
