The list of officials who have refused to report to the parliament includes acting Defense Minister Pedro Morenes and acting Development Minister Ana Pastor. Acting Interior Minister Jorge Fernandez Diaz has also said that he will follow their example.
The government will be able to avoid the court hearing in case the ministers cancel their decision and report to the parliament within a month.
Spanish parties have failed to form a government after over three months of negotiations and two unsuccessful parliamentary votes, via which the Socialists, the second-largest parliamentary faction after the Popular Party, attempted to form a coalition.
The Spanish parties have until May 2 to form a new government or elections will be held on June 26.
