The commission argued against the transfer of Derry to the Free State on basis that, whilst it had a Catholic majority, at 54.9% this was not large enough to justify such a decisive change to the existing frontier. Furthermore, whilst acknowledging that the economies and infrastructure of Derry and County Donegal were interlinked, it was deemed that transferring Derry to the Free State would only create similar problems between Derry and the remainder of County Londonderry, as well as counties Tyrone and Fermanagh. The commission judged that Derry's shirt and collar making industries would also suffer being cut off from their predominantly English markets. The proposal to redraw the boundary so as to follow the river Foyle was also rejected as it would divide the eastern and western parts of the town of Derry.
