the new Shia Family Law negates the need for sexual consent between married couples, tacitly approves child marriage and restricts a woman’s right to leave the home, according to UN papers seen by the Independent.

“It is one of the worst bills passed by the parliament this century,” fumed Shinkai Karokhail, a woman MP who campaigned against the law. “It is totally against women’s rights. This law makes women more vulnerable,” she added.

The law regulates personal matters like marriage, divorce, inheritance and sexual relations among Afghanistan’s minority Shia community. “It’s about votes. Karzai is in a hurry to appease the Shia because the elections are on the way,” Karokhail said.
