Lawyer Yousif al-Hirbish said the decision overturned an earlier appeals court verdict acquitting the three parliamentarians Falah al-Sawwagh, Bader al-Dahoum and Khaled al-Tahous. They will be able to avoid prison time by paying 2,000 dinars bail some USD 7,000.
The sentence foreshadows what may be the return of political unrest in Kuwait after months of calm. Activist Musallam al-Barrack has called for an opposition rally Tuesday, claiming that he will reveal sensitive information about alleged government corruption.
"They believe in their cause, and have announced their participation in a political protest this coming Tuesday," he said.
The three were arrested in 2013 after participating in rallies opposing changes to Kuwait's voting rules made by the ruling emir. The arrests came during a period of an escalating crackdown over perceived political dissent in the small, oil-rich country.
OPEC member Kuwait has the Gulf's most free-wheeling political system, but denouncing the emir is illegal.
