The bench expressed the surprise after hearing a writ petition challenging the legality of the conviction of Kurigram journalist Ariful Islam by a mobile court.
The court also set Monday to deliver its order on the writ.
Earlier on Saturday midnight, soon after picking Ariful up from his residence, a district mobile court sentenced him to one year imprisonment in a drug case.
The court awarded Ariful the jail term on charge of possessing half a bottle of liquor and 150 grams of hemp from his house.
