Public procurement contracts are contracts concluded as a result of the tender process, and the tender process is regulated by the public procurement procedure laws, which form the public procurement legislation. Established as the service unit of the Ministry of Environment and Urbanization in the Turkish administrative organization, the Head of the High Science Board is the examination and decision authority that can be operated at the request of the administrations in disputes regarding public procurement contracts concluded within the scope of construction work tenders for many years.in positive law. Two additional articles have been added to the Public Procurement Contracts Law No. 4735, which entered into force as of February 20, 2020, and significant changes have been made regarding the contract dispute resolution procedure of the Head of the High Science Board, the nature of the decisions to be taken and the scope of application. In this context, contractors are now also able to operate the process in which the Head of the High Science Board can examine and make decisions in accordance with the duty and authority of resolving disputes in public procurement contracts. It is considered that a contractor right is established with this procedure. Apart from this, upon the application of the administration or the contractor to the Head of the High Science Board, all of the decisions taken regarding the contract dispute subject to application have become absolute and binding for the parties. In this wise, the influence of the Head of the High Science Board on the disputed financial terms in public procurement contracts has also increased. These legal changes are very functional arrangements in terms of disputes in public procurement contracts, which the COVID-19 epidemic has affected like many other areas. However, these two legal amendments are only valid for public procurement contracts that are tendered under Law No. 4734 and contracts concluded under Law No. 4735. In this sense, the optional nature of the decisions taken upon the applications to the Head of the High Science Board has been changed, and although these decisions have become absolute and binding, the scope of the public procurement contracts that can be subject to application has narrowed. This situation leads to the deepening of many legal issues arising from the fragmented structure of the public procurement legislation. For this reason, these new regulations that make a difference in terms of contract disputes regarding construction work tenders carried out in accordance with the public procurement procedure laws other than Law No. 4735 need to be discussed.
