Prosecuting, Moses Mapanga told the court that on a date unknown to the state, Jonasi appeared on a South African television channel Afro Worldview Television where he insulted Mnangagwa.
Jonasi who on Saturday raised eyebrows when he announced that he was going to arrest the President and his deputies, Vice President Constatino Chiwenga and Kembo Mohadi for governance misrule also gave president Mnangagwa a six month ultimatum to resign.
He is being represented by Ntokozo Dube-Tachiona from the Zimbabwe Lawyers for Human Rights, (ZLHR) who challenged his placement on remand.
Dube argued that the state had no authority to prosecute the accused person since they did not have consent from the Prosecutor General.
She also challenged the 48 hour detention period which she argued had already lapsed by the time Jonas was brought before the court.
