Ahmadis are an end-times sect who consider themselves Muslim, but in a 1974 constitutional amendment were decreed a non-Muslim minority. They're not formally banned but live under severe restrictions and are not allowed to hold any gatherings.
According to the Jinnah Institute, nine cases of blasphemy were brought between 1929 and 1982 but surged into the thousands under the “Islamization” rule of Zia-ul-Haq.
In 2009, Pakistan's government approved a deal with the Taliban to implement Sharia law in the Swat Valley of the country's North-West Frontier Province. Yet Pakistan already has a Sharia court to deal with violations of the Hudood Ordinances, now know as the Women's Protection Bill. Extramarital sex for married Muslims carried a maximum punishment of death by stoning under the laws, with 100 lashes for unmarried couples or non-Muslims. The maximum punishment for drinking alcohol is 80 lashes, and theft can result in the right hand of the perpetrator being cut off. Rape or kidnapping a woman with the intent to commit sexual crimes carry the death penalty. However, unless a woman could provide four male witnesses to rape she could be tried herself under adultery charges.
When Pakistan revised the Hudood Ordinances with the Women's Protection Bill in 2006, the crime of rape was taken from the sharia jurisdiction and put under the civil law framework of the Pakistan Penal Code, eliminating the requirement for four male witnesses. The bill also outlawed statutory rape with an age of consent of 16. It also changed the punishment for someone convicted of having consensual sex outside marriage to imprisonment of up to five years and a fine. These reforms were criticized as un-Islamic by conservative groups and as not going far enough by human-rights groups, and are widely considered an attempt by the government to address criticism of its Islamic law by the international community.
Islamic parties have tried to pass legislation in Pakistan that would make apostasy -- when a Muslim leaves the religion -- a crime punishable by death. Under Islamic law, the apostate would have three days behind bars to repent before being executed.
