Restricting to people age 25+, Indian men average 8.7 years of education, and Indian women average 5.4 [1]. Add in the sclerotic nature of Indian courts, and unless I'm really misreading this data, it's hard for me to imagine that Indian women averaging an elementary school education are en masse closing this gap through legal maneuvers.

Maybe you're referring to a specific subgroup of women?
