The case, which has made headlines around the world, outraged much of Pakistan and threw the spotlight on the country's tribal courts, where women are stuck in the middle of feudal disputes driven by honor and revenge.
This year alone, dozens of rapes and "honor" killings of women have been registered in Punjab, with women slain by fathers, brothers and husbands for "crimes," including failing to conceive a child and refusing to become a prostitute.
In the latest incident, four men convicted of murder agreed to marry eight young women related to the men of the victims' family to settle the blood debt. (Full Story)
But in the case currently being heard in the Pakistani court, elders are alleged to have ordered rape as punishment for an alleged affair between the girl's younger brother and a woman from a tribe considered higher caste, the Matsoi clan.
Government prosecutor Ramzan Khalid Joiya told Reuters: "This incident was shocking for people in general."
The girl's father said he was forced to witness the incident in the village of Meerwala in the southern Punjab province while begging for it not to happen.
The defense denies that the tribal council, or panchayat, ordered the rape.
Mukhtaran Mai, a 30-year-old divorcee, says she was repeatedly raped after approaching the tribal council in Meerwala to settle the family dispute.
Parts of Pakistan still have a tradition of tribal justice where some crimes are punished outside the framework of the Pakistani legal system.
Mai, from the poorer Gujar family, says she pleaded with the Mastoi men to free her brother, who was kidnapped after they accused him of having an illicit affair.
While teenager Abdul Shakur denied the accusation, three Mastoi men, none of them involved in the current trial, sodomized him, wire reports quoted the Gujar family as saying.
She begged the council for mercy, but instead four men raped her and made her walk home semi-naked in front of hundreds of people, according to the prosecution.
