But with the new laws coming in about the compulsory enforcement of by-laws, one can argue that the letter of the by-law be enforced (or CTTT enforced) which goes further than the Regulation.
The regulation states – Restricting the playing of loud musical instruments and sound systems that disturb neighbours after 10 pm Sunday to Thursday, rather than after 12 midnight.
The fact that it disturbs neighbours at all (and at any time) would be in the by-laws.
