To achieve a fair trial, the role of the Guardian Council as the interpreter of the Constitution is of great importance. In fact, the fair trial concept in the constitution is an ideal that requires the determination of standards that the constitutional judge expresses during the examination of legislative approvals. Accordingly, this research seeks to answer the question: what are the  requirements for achieving an optimal fair trial according to the opinions of the Guardian Council? This study, using library data and an analytical-descriptive method, aims to identify the requirements of an optimal trial in three stages of judicial proceedings: 'before the judgment is issued,' 'issuing the judgment,' and 'executing the judgment.' The research concludes that the Guardian Council has implicitly and explicitly determined the guarantees and requirements for a fair trial and has deemed the legislative approvals of the Majlis incompatible with these standards in several instances.
