Right up until he was about to lose an election, then he suspended counting votes and tried to dissolve the Majlis in alliance with the communist party.
Not sure what you mean. In the -52 election he stopped the vote counting when enough of the majlis was filled that it could legally do work, and then tried to form a government which the shah blocked. This is what led to the proposal that the majlis give him six months of emergency powers.
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.
