I think that we all have bear in mind that the present bill has been badly worded.
If ANY piece of legislation can be misinterpreted it WILL be sooner or later.
Test cases WILL uphold the law AS IT IS WRITTEN not as it was originally intended.
This is why protest is important. The bill needs to be rewritten (preferably all PELS scrapped but that wont happen) before it kills off spontaneous sessions, acoustic music for fun and live music generally.
Once the tradition is broken it will probably be lost forever. This is the prospect that we are fighting, or at least I am.
