What are the most important fatwas regarding Islam's view of democracy, and what is the practical evidence for the failure of the idea of a democratic system, excluding evidence from the Quran and Sunnah?

The answer to this question requires extensive research and falls outside the specialization of the Fatwa Team. You may find an article titled: "Democracy from a Western Perspective," or refer to Fatwas No. 10238 and No. 39372, or consult an Islamic library.
