I like Frank Field. Perhaps more accurately, I should say I don't utterly despise him and would at least consider pulling him from a burning building. He is part of the Labour monstrosity that has pulverised, and still is pulverising, this country, but he's one of the honest ones. At least, he appears honest, which is more than can be said for MPs in general.

His expense claims were low in comparison with most of the others. He is surprised, therefore, to find that he is being asked to repay some. Well, you know, just because you didn't claim it all doesn't mean that the bits you did claim were entirely legitimate. 'Only' £7000-12000 per annum is an expense account most of us can only dream about. There are many who would love to have that as a wage! I have no expense account. Not one bean. Anything I want, I have to earn the money and pay for it. I do believe there may be a few others like me in the country in that situation, Frank, and who aren't going to be all that sympathetic, not even to one of the better MPs.

The excuse Frank put up is based on a motoring metaphor. Here's his version:

Criticising the decision by Sir Thomas to impose a £2,000-a-year limit on claims for cleaning and £1,000-a-year on claims for gardening, Mr Field said: "Imagine that you have been driving, perfectly legally, through a 30mph zone at a speed of 25mph. Imagine then your reaction when, five years later, you receive multiple fines as a decision has been taken to change, retrospectively, the speed limit to 20.

That's terrible, Frank. How can anyone do such a thing? Oh, but wait, let's reword your metaphor slightly:

Imagine that you have been driving, perfectly legally, a road-taxed vehicle with the tax always up to date. Imagine then your reaction when, five years later, you receive multiple fines as a decision has been taken to change, retrospectively, the tax rate you'd already paid to a higher one.

Are you getting the picture yet, Frank? Retrospective charges were your party's idea. You fight this and even you, Frank Field, one of the less despised members of that party, can look forward to the Twilight Zone of politics for the rest of your life.

Don't think the Tories can be let off with this either. They, too, are bleating about the unfairness of retrospective charges but I don't recall them fighting any of Labour's retrospective taxes at the time, nor have I heard any promises to repeal them and repay the unfairly-stolen money.

Retrospective lawmaking is a ridiculous concept. What I'm writing here isn't illegal now but tomorrow, who knows? Perhaps the tin of anchovies in my cupboard will be contraband tomorrow and my credit card checked retrospectively to see if I broke the law in the past. Even if I've eaten them and they're gone, I broke the law three months before it existed and so must pay.

This is not '1984'. This is not 'Minority Report'. This is not 'Nazi Germany'. This is far worse. Retrospective legislation means that laws can be applied or repealed at will and their effects extrapolated into the past. It means that all laws are irrelevant because they might not exist in the future and if they are repealed in the future, they've been repealed in the past. On the basis that any and all laws could potentially be repealed in the future and their repeal applied retrospectively, it can be logically argued that there are no laws now.

Imagine the society of the year 2500. It doesn't matter what you imagine it to be because all futures are equally possible at this point. What are the laws of that society? Well, they applied all their laws retrospectively so those laws are the ones that apply today. Imagine another, entirely different, future society. Their laws are retrospective so they apply today too. Applying retrospective legislation to the likely possibility of future societies could tie a prosecution lawyer into more knots than a Boy Scout could ever untie. Although there are no Boy Scouts in the future. There are the Gender Neutral Scouts, and the Girl Guides, thanks to 'equality'. But that's a different argument.

It is nothing short of disgusting to hear members of the Parliament that has applied all sorts of retrospective taxes to us all bleating now, when the same rules are applied to them. There cannot be a single person out there with an IQ above 'rabid leftie' who can have any sympathy with them at all.

You know how many of our current MPs I'd like to see retake their seats after the next election? None of them. Not one. They think they are Timelords now and can change the past by making its existence illegal. Get them out. Every last one of them.

Then pass a law that makes membership of their parties illegal and punishable by hanging.

And make it retrospective.
