Majestic Casino LTD was granted conditional permission for the change of use request by Donegal County Council but that has now been appealed.
The business, which currently operates as a casino, is located on the Port Road in Letterkenny.
This planning case has been criticised by Letterkeny Town Councillor Gerry McMonagle who had questioned why the premises continued to operate as a Casino while a change of order application had been made.
A Michael O'Neill of Solomons Hill formally opposed the application - he said the planning laws were being made a mockery of as An Bord Pleanala had refused a similar Casino development for which the council had also granted permission.
As it relates to the Magestic Casino application on the Ramelton Road - the council refused permission for the retention of advertising signage but permitted the change of use subject to a number of conditions.
Mr O'Neil has appealed that decision to An Bord Pleanala - the board is expected to make a decision by August.
