The fourth purchase attempt took place about 12.30pm, about the time of a security-staff changeover and the booth staff were unaware the new staff had not checked the ages as had been happening Mr Lawson said.
Citing legislation allowing a discharge if the impact could unduly outweigh the significance of the offending, Mr Lawson said that as a not-for-profit organisation, relying on sponsorship, charitable trust grants and proceeds from such big-match ventures as liquor sales, a conviction could harm the associations prospects for future fundraising.
Sergeant Flood accepted the offence was at the lower-end of the range of offending of its type, and said the association had not produced any evidence from organisations whose future support might be affected by a conviction against the association.
JPs Sandra McNeil and David Compton agreed a conviction had potential to adversely affect cricket association funding, the offending was at the lower end, and that "knowing" some of the people concerned they were sure the association had "learnt from this".
Police are expected to review the case before deciding whether to appeal the JPs' decision.
