Conservative religious lawmakers in Afghanistan blocked legislation on Saturday aimed at strengthening provisions for women's freedoms, arguing that parts of it violate Islamic principles and encourage disobedience.

The fierce opposition highlights how tenuous women's rights remain a dozen years after the ouster of the hard-line Taliban regime, whose strict interpretation of Islam once kept Afghan women virtual prisoners in their homes.

Khalil Ahmad Shaheedzada, a conservative lawmaker for Herat province, said the legislation was withdrawn shortly after being introduced in parliament because of an uproar by religious parties who said parts of the law are un-Islamic.

"Whatever is against Islamic law, we don't even need to speak about it," Shaheedzada said.

The Law on Elimination of Violence Against Women has been in effect since 2009, but only by presidential decree. It is being brought before parliament now because lawmaker Fawzia Kofi, a women's rights activist, wants to cement it with a parliamentary vote to prevent its potential reversal by any future president who might be tempted to repeal it to satisfy hard-line religious parties.

The law criminalizes, among other things, child marriage and forced marriage, and bans "baad," the traditional practice of exchanging girls and women to settle disputes. It makes domestic violence a crime punishable by up to three years in prison and specifies that rape victims should not face criminal charges for fornication or adultery.

Kofi, who plans to run for president in next year's elections, said she was disappointed because among those who oppose upgrading the law from presidential decree to legislation passed by parliament are women.

Afghanistan's parliament has more than 60 female lawmakers, mostly due to constitutional provisions reserving certain seats for women.

There has been spotty enforcement of the law as it stands. A United Nations analysis in late 2011 found only a small percentage of reported crimes against women were pursued by the Afghan government. Between March 2010 and March 2011 — the first full Afghan year the decree was in effect — prosecutors filed criminal charges in only 155 cases, or 7 percent of the total number of crimes reported.

Protecting rape victims contentious

The child marriage ban and the idea of protecting female rape victims from prosecution were particularly heated subjects in Saturday's parliamentary debate, said Nasirullah Sadiqizada Neli, a conservative lawmaker from Daykundi province.

Neli suggested that removing the custom — common in Afghanistan — of prosecuting raped women for adultery would lead to social chaos, with women freely engaging in extramarital sex safe in the knowledge they could claim rape if caught.

Another lawmaker, Mandavi Abdul Rahmani of Barlkh province, also opposed the law's rape provision.

"Adultery itself is a crime in Islam, whether it is by force or not," Rahmani said.

He said the Quran also makes clear that a husband has a right to beat a disobedient wife as a last resort, as long as she is not permanently harmed.

"But in this law," he said, "It says if a man beats his wife at all, he should be jailed for three months to three years."

Lawmaker Shaheedzada also claimed that the law might encourage disobedience among girls and women, saying it reflected Western values not applicable in Afghanistan.

"Even now in Afghanistan, women are running from their husbands. Girls are running from home," Shaheedzada said. "Such laws give them these ideas."

More freedoms for women are one of the most visible — and symbolic — changes in Afghanistan since the 2001 U.S.-led campaign that toppled the Taliban regime. While in power, the Taliban imposed a strict interpretation of Islam that put severe curbs on the freedom of women.

For five years, the regime banned women from working and going to school, or even leaving home without a male relative. In public, all women were forced to wear a head-to-toe burqa, which covers even the face with a mesh panel. Violators were publicly flogged or executed.

'We will bring it back'

Since the U.S.-led invasion in 2001, women's freedoms have improved vastly, but Afghanistan remains a deeply conservative culture, especially in rural areas.

Saturday's failure of the legislation in parliament reflected the power of religious parties but changed little on the ground, since the decree is still the law of the land, however loosely enforced. Kofi said the parliament decided to send the legislation to committee, and it could come to a vote again later this year.

"We will work on this law," she said. "We will bring it back."

Some activists, however, worry about potential changes to the law. Bringing the legislation before parliament also opened it up to being amended, leaving the possibility that conservatives will seek to weaken it by stripping out provisions they dislike — or even vote to repeal it.

"There's a real risk this has opened a Pandora's box, that this may have galvanized opposition to this decree by people who in principle oppose greater rights for women," said Heather Barr, a researcher for Human Rights Watch.

That's true for lawmaker Rahmani, who said President Hamid Karzai should never have issued the decree and wants it changed, if not repealed.

"We cannot have an Islamic country with basically Western laws," he said.
