In his legal treatise, Institutes of the Laws of England (1628), Sir Edward Coke wrote,
A man’s house is his castle and fortress, et domus sua cuique tutissimum refugium (and each man’s home is his safest refuge).
This general legal principle, carried into common law, implied that no one may enter a person’s home without permission. Well, those days are indeed over [see here] as the British government starts its rollout of smart gas and electricity meters for every household. The dream for this $20 billion project, (or $400 for every household), is to reduce energy consumption and possibly save the planet.
Not that we don’t want to give utopian statism its due but what could possibly go wrong. And yes, you will lower the drawbridge, empty the moat and allow Gaz and Leccy to install something you do not want. Or else.
