Narrative:
On taxi-out I was the first officer checking the flight controls. I could feel a definite hang-up in the ailerons as I displaced the yoke. We returned to the gate and maintenance checked the control wheel movement. After looking at the cables and cleaning some of the actuators they cleared the controls as ops checked good. When we checked the ailerons the restriction to movement had not changed. Even though the aircraft had been cleared to fly we refused the aircraft as un-airworthy. I am concerned that a noticeable and unidentified problem in the flight controls was released to fly.
