President Hamid Karzai on Saturday approved the second of two new election laws designed to pave the way for smooth transition of power in Afghanistan next year.
Mr Karzai’s signature on the law, which determines how presidential and provincial elections will be run, is expected to alleviate international concerns that the ballot could be delayed or its credibility could be at risk.
His office said Mr Karzai’s decree meant the law had come into immediate effect.
Mr Karzai on Wednesday approved a bill giving more power and independence to the electoral complaints watchdog, which was integral to unmasking massive fraud at the last presidential election in 2009.
Donor nations have been pressing Kabul to pass the election laws, seen as crucial to proving that the 12-year war and billions of dollars of aid money have not been in vain.
Afghanistan is due to elect a new President and council members for its 34 provinces on April 5, with Mr Karma’ barred from running after serving a maximum two terms.
A corrupt election and a contested result would undermine efforts to establish a functioning state in Afghanistan, where some fear the risk of another civil war as Taliban rebels fight to regain power.
US-led Nato combat troops are due to withdraw at the end of 2014, just months after the election.
