Gracchi has already blasted the "Ministry of Truth" film calling for a lying by politicians to their electorate to be made illegal. He points out that one man's lie is almost always another's truth. That truth itself is an uncertain commodity in politics. Unity, at the original Ministry of Truth, argues that the programme is based upon a flawed conception of the British constitution.
When I first saw the film a couple of weeks ago I was endlessly frustrated by the programme's failure to consider the unintended consequences of such a law. The massive problems the proposed law would create seem pretty obvious but the film didn't address them at all. Here are two big ones:
1) What is a lie?
Incautious statements, mistakes, exagerrations as a result of differing priorities and values sets and simple disagreements with a heavy majority have all been termed lies over the years. These are not the outright lies that the programme clearly aimed to prohibit but disentangling straight "he said this when he absolutely knows that it is untrue" lies from statements which are more difference of opinion than lie would be an essentially arbitrary process in many cases. The massive grey area that surrounds lying would make for messy, unpredictable and possibly arbitrary legal sanction.
2) Giving the courts a veto over candidates for office
This law would mean that the courts would rule on whether a politician had lied or not and, on the basis of that ruling, whether they can stand for office. That would mean that rule by the people would be replaced by rule by the legal oligarchy. Ordinary voters would only be allowed to choose within the confines of honest and trustworthy politicians not condemned by the courts. We would be using lawyers instead of theologians but otherwise our system would bear a marked semblance to Iran's.
The legal process isn't perfect. It can be abused by those with better lawyers or the sympathies of an unrepresentative legal community (very capable of swaying juries if this is a matter for jury trial). The courts have already, in my opinion, gone too far in assuming a power to fight democratic decisions. No body so free from democratic accountability should be given such broad powers to decide who is fit for office.
