The idea
Remove the unnecessary requirement for shops, offices and other public buildings to display a sign stating that smoking is against the law. There are lots of laws that apply all the time and we don't need signs reminding us what is illegal and what is not, so why do the owners of premises have to put up a special sign for this particular one?
Why is it important?
The requirement is totally unnecessary. If removed it would save time and money for businesses which have to observe it, and local authorities and the courts which have to enforce it, leaving them time to pursue more important issues of public protection.
