Narrative:
Aircraft arrived at the gate; was parked according to SOP; including chocks. Jetbridge was pulled up to the door; canopy was deployed; and aircraft began to move backwards away from the building. Ramp noticed movement; aircraft stopped suddenly as if the brakes had been applied. A supervisor; myself; was called to the gate and I assessed the situation. No damage; but aircraft had rolled about 3 ft. The nose chock remained behind the wheels; the right main rear chock had been displaced and essentially pushed out of the way of the wheel. I spoke with the captain who reported that the brakes were on the entire time and had not been released. Upon viewing the video; there is no discernible way to tell if the wheels were rolling or not and we are unsure as to what caused the movement. I'm hesitant to believe that it was a slide and not a wheel roll due to brakes being off. The ground surface contamination is minimal with typical ramp grime; sand; and no ice. We used [a standard] chock.
