If there are objections, there is a difference between an objection made within the stipulated period by a qualifying person and an objection by anyone else.
The objections are considered by the minister, who may disregard invalid objections. If there remain one or more objections from qualifying persons that have not been disregarded or withdrawn, then the minister must arrange a public inquiry (unless all the remaining objectors agree that the remaining objections can be dealt with in writing).
