Liberty By Law

In the run-up to my sister's wedding and the trip around it, I somehow allowed it to slip my mind that we were passing the 800th anniversary of the Magna Carta.

But, to give it its full name, Magna Carta Libertatum (my italics - I don't think they had 'em back then) gets it the right way round. It was in some respects a happy accident. In 1215, a bunch of chippy barons were getting fed up with King John. In those days, in such circumstances, the malcontents would usually replace the sovereign with a pliable prince who'd be more attentive to their grievances. But, having no such prince to hand, the barons were forced to be more inventive, and so they wound up replacing the King with an idea, and the most important idea of all - that even the King is subject to the law.

On this 800th anniversary, that's a lesson worth re-learning. Restraints on state power are increasingly unfashionable among the heirs to Magna Carta: in America, King Barack decides when he wakes up of a morning what clauses of ObamaCare or US immigration law he's willing to observe or waive according to royal whim; his heir, Queen Hillary, operates on the principle that laws are for the other 300 million Americans, not her. In the birthplace of Magna Carta, a few miles from that meadow at Runnymede, David Cameron's constabulary leans on newsagents to cough up the names and addresses of troublesome citizens who've committed the crime of purchasing Charlie Hebdo.

The symbolism was almost too perfect when Mr Cameron went on TV with David Letterman, and was obliged to admit that he had no idea what the words "Magna Carta" meant. Magna Carta Libertatum: The Great Charter of Liberties.
