Unicameral By Stealth: Tony Abbott's Senate Referendum Call

The Australian (Tony Abbott calls for Senate referendum, warns 'we are turning into Italy') reports that relevance-deprived ex-PM Tony Abbott has called for a referendum to reduce the power of the Senate to obstruct government legislation.

As outlined, the plan would allow for a deadlock between the Houses to be broken by a joint sitting of both Houses without the need for a prior double-dissolution election.  It appears that this follows one of two options outlined in this 2003 discussion paper on resolving deadlocks.  These options were:

1. A joint sitting can be convened after a bill has been rejected twice with three months between rejections
2. A joint sitting can be convened after every election for the full House and half the Senate, rather than requiring a double dissolution

It appears Abbott favours the first option, but this is not yet totally clear.  The 2003 proposals were killed off based on a finding that they would not pass a referendum.
