The essay includes two parts. The author presents the first part with the history and background of "Proof-based Consensus" and the decrees of jurists and fundamentalists over its authenticity. He concludes that most of late and contemporary jurists do not believe the proof-based consensus to be authentic, however, some of them and early and past jurists hold the contrary idea.In the second part, he evaluates the proof-based consensus considering different basis of authenticity of the consensus. He concludes that due to Imam-supported, blessed, and supposed consensus, and some of the suppositions of asserted consensus, proof-based consensus can be considered as authentic. On the other hand, he declares that due to the discovered consensus by genuine proof or based on the approval of Imam Mahdi (A.S.), and some of the suppositions of asserted consensus, proof-based consensus cannot be authentic.
