The Civil Court on Wednesday ruled the state of emergency cannot be used as a reason for clamping down on the anti-government demonstrators.
The court also prohibited the use of force against the protesters, whose demonstrations have so far been conducted peacefully. This is in line with an earlier ruling by the Constitutional Court.
Former Democrat MP Thaworn Saeniam asked the Court to revoke the emergency decree invoked in Bangkok and outskirts provinces.
Yingluck government has invoked the state of emergency to handle with the anti-government protests led by former Democrat MP Suthep Thaugsuban in January.
