newspapers once a month, displaying all the Development Plan applications (here after

developers/ owners of the plots under the council’s purview.
General public members are allowed to raise objections against the applications that appear
on those advertisements within a certain period of time, such as two weeks from the date of

application details. The council maintains all such objections even if they are from an
anonymous member of the public.
