Narrative:

Air carrier X, a 727 was inbound on the STAR, level at 6000. Small aircraft Y, C-185 was VFR outbound at 5500 ft. Traffic was exchanged when the aircraft were 5 mi apart, both level at their respective altitudes. Both aircraft reported the other one in sight. As they were passing, 1/2 mi laterally, air carrier X advised 'we're climbing for traffic.' I rogered him. Air carrier X only climbed 100 or 200 ft and was never a confliction with anyone, however, I felt it was an unnecessary maneuver, since the aircraft were separated, had visual contact with each other, and were passing 1/2 mi apart.

Title: ACR X TCASII RA WITH VFR SMA Y. EVASIVE ACTION CLB. SEE AND AVOID CONCEPT.

Narrative: ACR X, A 727 WAS INBOUND ON THE STAR, LEVEL AT 6000. SMA Y, C-185 WAS VFR OUTBOUND AT 5500 FT. TFC WAS EXCHANGED WHEN THE ACFT WERE 5 MI APART, BOTH LEVEL AT THEIR RESPECTIVE ALTS. BOTH ACFT RPTED THE OTHER ONE IN SIGHT. AS THEY WERE PASSING, 1/2 MI LATERALLY, ACR X ADVISED 'WE'RE CLBING FOR TFC.' I ROGERED HIM. ACR X ONLY CLBED 100 OR 200 FT AND WAS NEVER A CONFLICTION WITH ANYONE, HOWEVER, I FELT IT WAS AN UNNECESSARY MANEUVER, SINCE THE ACFT WERE SEPARATED, HAD VISUAL CONTACT WITH EACH OTHER, AND WERE PASSING 1/2 MI APART.
