Perhaps the licensee (with others recently affected) can first explore if there any alternatives, other than closing the session or obtaining the PEL?

Remember that the Council have to prove that the participants were 'performers' and that more than two, will have automatically made these licensed premises unsafe for the public, dispite the pub having to be inspected (by the same Council) and hold a justices's licence.

If you are unsafe now, why did the Council fail to protect you before?
