In Turkey, many of the governmental authorities shall apply to
procurement of goods, services or works under Public Procurement
Law #4734 (PPL). In the same manner, the contracts in public
purchase of goods, services and works refer to this law's
"contract principles" indicated in the Public Procurement
Contract Law (#4735) (PPCL). But it had better to lay emphasis on
an exception for defense issues under law#4734.
Exception in PPL#4734 stipulates that the procurement for
defense, security or intelligence related goods, services and works
decided by the relevant ministry and require to be treated
confidential, and procurements requiring special security measures
during the performance of the contract pursuant to related
legislation or those concerning the cases in which the basic
interests of the state's security needs to be protected shall
not be governed by this Law except prohibition and criminal
provisions.
