Another significant initiative introduced by Teymourtash during his tenure as the Minister of Public Works was the introduction of legislation annulling the French monopoly concession for excavating antiquities in Iran in a bid to usher in an open door policy whereby excavators from other countries could assist in unearthing Iranian national treasures and antiquities. As Murray, the American Minister to Tehran noted at the time, “Meanwhile the indefatigable Sardar Moazzam, Minister of Public Works, has introduced to the Medjliss his bill which proposes the abrogation of all Imperial firmans and concessions obtained thereby, which will of course include that held by the French”. Although the bill was originally conceived and drafted while Teymourtash served as Minister of Public Works, it finally secured passage through the Majles in 1927.
