A gazette notice appointing the five member commission was issued Saturday night.
The commission has been entrusted to carry out an impartial and complete investigation into the attacks and identify persons and organisations directly or indirectly connected to the terrorist attacks.
It has also been tasked with identifying officers and authorities who failed to anticipate that terrorist activities of this nature would take place within the country. The commission is required to submit an interim report in three months, a subsequent interim report in the next two months and the final report in six months.
The Presidential commission has been appointed just weeks ahead of the Presidential election scheduled for November 16.
President had appointed a three-member committee to investigate the incident following the Easter Sunday attacks and the committee handed over its report to the President in June.
The report was not made public but was handed over to Attorney General office for action. The country’s police chief and former defence secretary have been charged with criminal negligence for the tacks which killed over 260 people including 45 foreigners.
Meanwhile, a Parliament Select Committee was also appointed to record statements related to the attacks and the committee will submit its report next month.
