The Taliban say they will temporarily adopt the 1964 monarchy constitution except for those clauses that contradict Sharia law and the values of the ruling Islamist group.
The justice ministry announced the decision to enforce the constitution that was in vogue during the reign of King Mohammad Zahir Shah with some amendments.
Taliban spokesman Qari Saeed Khosty told EFE that it might also include the functioning of the current interim government.
However, any clause that the Taliban consider contradicts Sharia law and the principles of Islamist militia would be changed or removed.
The text enforced for a brief period of constitutional monarchy from 1964 to 1973 is considered moderate and protects Muslim and democratic rights of the Afghans and is friendly to international conventions.
The constitution grants Afghan men and women the right to vote to elect MPs.
The Taliban seized power in Kabul on August 15 after president Ashraf Ghani fled to the United Arab Emirates.
The Islamist militia has pledged an inclusive approach to governance and promised that their administration would protect the rights of women.
During their previous rule from 1996 to 2001, they did not allow girls to attend schools and banned females from public life.
The Taliban formed an interim government earlier this month but they included no women in the administration.
"It is the most moderate constitution. The only problem is its monarchy part that could be suspended or amended," Zalmay Hewadmal, a Kabul University Professor, told EFE.
He recalled that the Afghan interim government formed in 2001 under Hamid Karzai in Germany also implemented the constitution but removed monarchy.
"The King Zahir Shah's constitution ensures all Islamic, national and international values and principles," said Hewadmal, who was the cultural aid of Karzai.
