There is no absolute mandate to pursue an agenda that has not, at the very least, been placed out before the voting public for dissection and analysis and review.
I took the liberty of keeping a copy of every major party's policy statement PRIOR to the 2010 election, and I can safely say that not only did the incumbent party, once in power - NOT abide by its own policy as stated to the public - but actually launched on a different program entirely.
There was ZERO suggestion of any '50% women CEOs" or the equally mythical "Women in combat" in the Labor policy platform, and these were issues never aired before the general public before that election, so NOBODY got any chance to review these before that election.
This form of 'mandate' is not only a false application of the privilege of political power - it is a deliberate lie sold to the public by omission - and as such deserves to be struck down by that same public.
I have previously stated that it is the duty of the 'courts' to review legislation ( and most importantly, regulation and departmental policy) to ensure that it complies with the rule of Law - and NOT to accept the 'law as written' as automatically in effect. You saw an example of this with the Dr Haneef affair - following which striking down by the courts, the government sought to bring in legislation to change the rules in an attempt to ensure that it 'won' such issues.
That style of seeking after a solution that places all the cards in the hands of the accuser (government etc) is anathema to the rule of Law and to democracy, and should rightly ALSO be struck down by the courts.
Where the courts and the government form a single monolithic structure and work as one to ensure the enshrinement of legislation that abrogates the Rule of Law - there remains the right and the duty of The People to strike it down.
'...that whenever any form of Government becomes destructive of these ends (life, liberty and the pursuit of happiness), it is the Right of the People to alter or abolish it., and to institute new Government, laying its foundation on such principles, and organising its Powere in such Form, as to them seem most likely to effect their Safety and Happiness.
Prudence, indeed, will dictate that government long established should not be changed for light or transient Causes; and accordingly all Experience hath shewn, that Mankind are more disposed to suffer, while Evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed.
But, when a long Train of Abuses and Usurpations, pursuing invariably the same Object (abolition of the Forms to which the populace are accustomed), evinces a Design to reduce them under Despotism, it is their Right, it is their Duty, to throw off such Government, and to provide new Guards for their future security'.
