An Islamic practice permitting men to instantly divorce their wives has been declared unconstitutional by India’s supreme court after decades of campaigning by women’s groups and victims.

The “triple talaq” has allowed Muslim men to dissolve marriages by pronouncing the word “divorce” three times.

A national survey conducted in 2015 by the BMMA found roughly 1 in 11 Muslim women were survivors of triple talaq, the vast majority receiving no alimony or compensation.
