It considers personal licence applications when there are objections or unspent convictions, and premises licence applications for new licences, variations, or club premises certificates when representations are received or the police object. The sub-committee also reviews existing premises licences, club premises certificates, and considers objections to temporary event notices, impacting businesses and individuals seeking or holding alcohol and entertainment licences.
