Liberal stagehand John Mraz suggests a legislated end to heckling.

Ironically, Parliament ought to legislate itself into silence. Just as an alcoholic has lost the right to that first drink, our politicians have the lost the right to heckle.  They clearly can’t handle the responsibility.  A private member’s bill banning heckling outright should be drafted, introduced and passed by unanimous assent — and then enforced.  No doubt some traditionalists and rabid free-speechers would be aghast.  But I challenge any MP to declare that they believe they should have the right to shout at work.   Because aside from rock stars, floor traders and a few other crazed specialists, 99% of civilized society does not.
