BAGHDAD - Iraq's parliament pushed through a law Tuesday meant to pave the way for U.S.-backed provincial elections that will redistribute regional power. But the measure was clouded by a Kurdish boycott, and critics predicted the ballot won't be held this year.

The measure still needs to be approved by Iraq's three-member presidential council, which is led by Kurdish President Jalal Talabani, adding significance to the Kurdish objections.

Kurdish legislators, along with the two deputy parliament speakers, walked out of the chamber after lawmakers decided to hold a secret ballot that included in the law a requirement for ethnic power-sharing in the disputed oil center of Kirkuk.

Kurds' opposition to the equal distribution of provincial council seats among Kurds, Turkomen and Arabs in the Kirkuk region -- outside Kurdish territory but considered by many Kurds to be part of their historical land -- has been a major factor in stalling passage of the election law.

Holding elections for governing councils in Iraq's 18 provinces is seen by U.S. officials as another key step toward repairing Iraq's sectarian rifts. Many Sunni Arabs boycotted provincial balloting in January 2005, enabling Shiite Muslims and Kurds to win a disproportionate share of power.

A preliminary election law passed this year had been touted as a sign that Prime Minister Nouri al-Maliki's government was making progress on the political front in addition to security gains. But the Iraqis then deadlocked over the follow-up law setting guidelines and allocating funds for the vote, which had been planned to begin Oct. 1.
