Undoubtedly, one of the most important tools of the law science for setting the relations between the citizens in any country is the legal institution of contracts that is used mostly in economy, trade and commerce and it is one of the common legal institutions in all contemporary legal systems with its unique characteristics. On the other hand, this legal institution has been used not only by the private sector but also by the governmental organizations and departments by concluding it in various forms such as administrative and public contracts that has left some daily affairs to the private sector and continues its specialized supervision. One of these common contracts is gas station contractual contracts and establishment of gasoline, oil, gas, single-purpose and dual-purpose CNG stations. A look at the legislative system indicates that the Islamic Council has avoided legislation in this field and left this important task to the Ministry of Petroleum and the National Oil Products Distribution Company.. The results of the research prove that these types of contracts are close to administrative and government contracts and by distancing from the balance of contracts in private law, there will be a type of contractual inequality when concluding a contract between the employer (National Iranian Oil Products Distribution Company) and the contractor (private broadcast) that the employer considers this type of contracts from the position of power.
