The GSD says the Government can't deny that after 13 years of mismanagement, it's now having to resort to outside private investment for the Upper Rock.
It says this is an extensive area of land, and the Government has failed to explain why such a short period of time has been allowed for proposals, and why such little publicity has been given to the project.
It says many people are concluding that a preferred bidder may have already been identified.
GSD Spokesman Damon Bossino says it's shameful that Minister John Cortes has chosen to personally attack and insult him instead of dealing with these issues.
