According to Amnesty International, the public prosecutor called for 29-year-old Ghomgham and other defendants to be beheaded. Most people executed in the Gulf kingdom are beheaded with a sword, according to Reprieve, an international charity focused on the death penalty.
The charges against the group that Ghomgham is part of include incitement to protest, chanting slogans hostile to the regime, attempting to inflame public opinion, and providing moral support to rioters.
Women have been granted permission to drive and more freely work outside the home, and the country's fearsome religious police have been defanged.
Meanwhile, President Donald Trump and Jared Kushner, his son-in-law and senior adviser, have embraced the crown prince as a close and crucial partner in the administration's Middle East strategy. Trump went to Saudi Arabia — an absolute monarchy where political parties and protests are banned — in his first foreign trip as president.
Rights groups worry that the execution of a woman for non-violent offenses would set a precedent.
Zayadin added that Ghomgham's case “provided a window” to an intensifying crackdown that had already swept up peaceful women’s rights campaigners.
Samah Hadid, Amnesty's Middle East director of campaigns, said the death sentence would "send a horrifying message that other activists could be targeted in the same way for their peaceful protest and human rights activism."
The prosecution of Ghomgham was reported earlier this week by Berlin-based European-Saudi Organisation for Human Rights and ALQST, a London-based rights group.
The charges are related to Ghomgham's involvement in huge demonstrations in Saudi Arabia's Eastern Province — where most of the country's Shiites live — that started in 2011.
She was arrested in December 2015 with her husband, Moussa al-Hashem, who is also charged. Their next court date is scheduled for Oct. 28.
Shiites have long complained of widespread discrimination by Sunni Muslim authorities, who deny unfairly cracking down on the minority.
The Saudi government also accuses arch-rival Iran of being behind unrest.
In Jan. 2, 2016, Saudi authorities executed 47 prisoners including Nimr al-Nimr, a revered Shiite cleric and government critic from the Eastern Province who had been convicted of sedition and other charges.
