Narrative:
The commuter was on a heading for a visual approach descending to 4000 ft then I saw a VFR at 5500 ft. The commuter's altitude was in the coast mode because the radar was bad. Once I saw his altitude, 6300 ft descending, I amended his altitude to 6000 ft and left turn to 100 degrees because I saw the C182 altitude climbing out of 5800 ft. The commuter said that would not work. The plane was then turning towards him. I talked to the commuter pilot and he advised me, C182 was no way VFR. TCASII paperwork filed by myself and the commuter pilot.
