As per Article 243T of the Constitution of India, what is the minimum proportion of seats that must be reserved for women in every Municipality? 

Article 243T(3) mandates that "Not less than one-third (including the number of seats reserved for women belonging to the Scheduled Castes and the Scheduled Tribes) of the total number of seats to be filled by direct election in every Municipality shall be reserved for women and such seats may be allotted by rotation to different constituencies in a Municipality." Additionally, Article 243T(2) requires that not less than one-third of the SC/ST reserved seats must be reserved for women belonging to those categories. These provisions ensure robust representation of women in urban local governance and are mandatory across all States.
