A developer planning to build a large holiday resort in Cornwall is facing a public inquiry into the scheme.
Planning permission was first granted for the scheme in 1991
Ampersand has planning permission for more than 500 holiday flats at Carlyon Bay near St Austell.
But opponents have won a public inquiry into proposed sea defences at the £200m beach complex.
They are concerned the sea wall would require enormous quantities of imported sand and there would be a need to keep replenishing it for years.
Planning permission to build 511 holiday homes was granted in 1991 and renewed in 1996.
Company Director Tim Renwick said: "Ampersand is disappointed that the government has decided to order a public inquiry into its plans to improve the sea defences for which it already has planning permission.
"We are convinced that better sea defences and improved public access is by far the best solution for the beach."
The company had offered to carry out sea defence work worth £3m last May.
However, Ampersand could press ahead, relying on a smaller sea wall because it already has consent.
Any public inquiry is unlikely to take place before summer this year.
