Ignorantia juris non excusat (ignorance of the law is not a lawful defence).
I think I would be more acceptable to hold a populace to the whole ignorance is no excuse argument, if the politicians weren't creating laws so damn fast, and our media wasn't making such a complete hash of the communicating the actions of parliament.
Under the labour government (not knocking them specifically but I don't have stats for the current scum), they introduced an average of 1 new offence every day. The media hasn't exactly been making a weekly listing of all the new offences we have to be aware of have they? Section 13 of the terrorism act 2003 always made me worry that it was open to abuse... the 1980 bee act has always made me concerned for the rights it give bee keepers in terms of access to my hovercraft (full of eels or not)...
And as a group that spend a lot of time in the woods, I'm guessing we could all be found guilty of an offence under Grey Squirrels (Prohibition of Importation and Keeping) Order of 1937 (now repealed)...
People are more likely to be able to rattle off a list of what they think are laws imposed by Brussels that are in fact wrong (straight bananas and acrobats wearing hard hats for example), than they are to know actual laws that have been passed by Her Majesty's Government...
And anyone who thinks that repealing the human rights act is the answer, remember, the 1689 bill of rights has been entirely repealed with the exception of the introduction... That includes your right to bear arms which was revoked by the Police and Fire arms act 1921...
But we digress. Congrats to the OP on your successful appeal, and for waking a lot of people upto what the LEZ is.
