Public law concession agreements, contracts between administrative and private law real or legal entities. Contracts aimed at ensuring the provision of services without undergoing high financial "burdens". In the case of disputes concerning public service concession agreements, preference is given to settlement disputes with arbitral jurisdiction rather than the settlement of court disputes, usually by private contracting parties. In our work, firstly we will give information about the concept of public service concession agreement and arbitration, then, in the Turkish administrative law, the "obstruction of arbitration", which will rule until 1999, and the elimination of the ban will be discussed. Later, the elements and procedure of the arbitration will be examined in detail in the context of "recent changes", followed by the determination of the substantive rules of law to be applied to the merits of the dispute in the arbitration proceedings, and finally, to be given information about the decisions to be made on the basis of the arbitration proceedings.
