The attendance number thresholds have not been included in the body of the Bill; the intention is to prescribe the appropriate thresholds in regulations to be made under it. This reflects the advice of fire authorities in relation to the operation of the licensing system. The thinking behind this approach is to provide for flexibility in the system for prescribing classes of indoor events within the approved thresholds into the future by the Minister as and when required. It will also enable the Minister to deal speedily with any deficiency identified in the licensing arrangements needing urgent remedy and which may be posing a risk to public safety.
