Exploring the crimes of economic corruption is of great significance due to its great effect on public opinion. The request of the former head of the judiciary from the leadership to establish a special court for economic corruption can be evaluated in this regard. In this paper, an attempt has been made to study the legal jurisprudence of investigating the crimes of economic corruption in the light of a fair trial. The present paper is an analytical descriptive study, applying the library method. The results indicate that the broad jurisdiction provided for in the suggested proposal and authorization of the former head of the judiciary to establish a special economic court to deal with economic crimes violated the rights of the accused persons, which are based on jurisprudential rules and domestic and international law, to enjoy the principles of a fair trial, widely and even irreparably because determination and speed are not necessarily provided through limited means by depriving defendants of their legal rights, which have been tried for years to establish. The examples of defendants' legal rights consist of holding fair trials, a proper judicial process during the trials, the right of access and free choice of lawyer, the right to appeal, having legal notice and objections, and protesting against temporary detention, which in the obvious form was ignored by violating some of the rules of criminal procedure. The conclusion is that the establishment of special courts and authorities can only lead to justice in the proceedings if it is in line with a fair trial.
