The decision is expected to be announced in the coming days.
A review was launched in August after a crackdown by the authorities on supporters of ousted President Mohammed Morsi left hundreds of people dead.
On Sunday, more than 50 people were killed in clashes between Morsi supporters, opponents and security forces in several cities.
Thousands of members of the Muslim Brotherhood have also been detained in the past two months. Several senior figures, including Mr Morsi and the movement`s general guide Mohammed Badie, are being held on charges including incitement to violence and murder.
The authorities portray the crackdown as a struggle against "terrorism".
