Anyone else here remember when there was a thing called ministerial accountability and ministers would. Step aside while these enquires were in progress or even actually resign?
examples of the 'ministerial accountability' you're pining for... the "step asides, the resignations"?
Used to be the established practice back in the seventies and before, now it is hang on until you are dragged out. Not a Liberal phenomena, it's common to all parties now.
so ya gots nuthin then, hey!
