Pagan Amum, the secretary general of South Sudan's ruling SPLM party, has petitioned the court to cancel the president's order that bars him from speaking with the media and leaving the country's capital Juba.
Besides suspending Amum, President Salva Kiir also dismissed his entire cabinet last month.
According to Amum's legal team, Kiir, who is also the chairman of SPLM, is not legally entitled to impose these restrictions.
