Papers relating to an attempt by Elfyn Llwyd to change planning law with a 10 minute rule bill to prevent developers from keeping planning permission active for decades by carrying out a very small amount of work related to construction but never completing the development. This relates to a planning permission granted in Aberdovey in the 1960s for a development which was never completed and which affected applications for other developments in the area.
