According to the Islamic Republic Constitution, women are considered second class citizens, valued as less than men. These laws set the stage for series of social and legal practices that systematically disadvantage women through compulsory veiling, age for marriage, divorce proceedings, custody of children, access to birth control and abortion, tort and justice against assailants, employment and entrepreneurship, inheritance, ownership, government service and travel.
Many girls are forced into prostitution, married off early, are deprived of an education and other opportunities. Sexual assault and rape are regular occurrences. In a legal and religiously hostile environment for women and girls, poor observance of modesty rules or the hijab are often perceived as “invitations” for such violent acts.
Mandatory hijab goes beyond the physical limits that are imposed on women. Women aren't permitted to travel without the consent of a male “guardian.” Female participation in the labor force is discouraged. In colleges and universities, in the inheritance laws, and regarding child custody, women are systematically discriminated against.
