Maybe so but they aren't the law! Its down to W&M legislation.
Remember the who-ha in the UK when Arthur tried to prove that his stout head was part of the pint?
I think he won the case in the UK!![/quote:2hae7aoi]
I don't think the law specifies whether head is part of the measure or not, so it would take just such a case to set the precedent.
If someone were to take such a case, the publican could point out fact that brim fill pint glasses are not only considered legal, but are by far the most common glasses used to serve beer in pubs and have been for generations. As beer of any kind will have a head on it, it is impossible to serve a liquid pint + extra head in such a vessel. This would give him/her a very strong argument that the head has always been considered part of the pint by publican and customer alike. The law may not specify whether the head is part of the pint, but custom and practice has established that it is and the fact that the NSAI[/url:2hae7aoi] certifies brim fill pint glasses seems to indicate that the sate metrology service agrees.
