An Alexandria court suspended the sentence handed down to leftist activist Mahienour al-Massry on Sunday, ordering her release.
A request for the suspension was filed at the Misdemeanors Court on Thursday, which scheduled a review for Sunday.
Massry was jailed last May after an appeals court affirmed a two-year sentence against her and eight others for breaking the Protest Law by demonstrating outside a court that was trying two policemen accused of killing Khaled Saeed.
Last July however, the court reduced her two-year sentence to six months and a LE50,000 fine.
On August 25, Massry started a hunger strike in solidarity with Alaa Abd El Fattah and other political detainees.
Since her detention, she has won the French 2014 Ludovic Trarieux International Human Rights Prize, given annually to a lawyer for contributions to the defense of human rights. The first award in 1985 was given to South African leader Nelson Mandela during his imprisonment.
Massry is also on trial in the Raml police station case, in which she is accused, along with 12 others, of damaging and storming the police station and injuring policemen.
