I don’t have the book I’m looking for handy but the consensus opinion of historians of Iran is that it was an illegitimate move, as explained by Ervand Abrahamian in “ Evolving Iran: An Introduction to Politics and Problems in the Islamic Republic”. Tellingly his first act after seating a half empty Majlis was to have them grant him emergency powers that allowed him to dictate laws. This is not a democratic system.
