"We will take a decision after the CBI inquiry is over," he told reporters here.
Antony was asked if the Defence Ministry had decided anything on the fate of the scam-tainted building in view of the recommendations made by the Environment Ministry and Army's Southern Command.
The CBI, which is probing the scam, is also likely to give its recommendations as to whether the building constructed next to a sensitive naval base is a security threat and whether it should be demolished or given to the Defence Ministry for public use.
Defence Ministry had recommended a CBI probe after it emerged that flats were alloted to several senior serving and retired military personnel including three former Service chiefs.
On Sunday, the Environment Ministry recommended that the 31-storey building be demolished within three months as the project in Mumbai's upmarket Colaba was "unauthorised" and violated coastal regulations.
