Narrative:
TCASII resolution. A learjet (military) was departing hif climbing to 9000. A dc-9 was inbound to slc during an arrival bank at 10000. Traffic was heavy and frequency congested. Traffic was exchanged. After the dc-9 had passed the learjet, the dc- 9 advised he'd had an RA and had climbed. I looked and observed the dc-9 at 10600 ft. Traffic flow was affected as the dc-9 was a little high as he passed the slc airport.

Title: AN ACR DC-9 RESPONDED TO A TCASII RA AND CLBED WITHOUT CLRNC. TFC WAS CLBING TO ALT BELOW DC-9.
Narrative: TCASII RESOLUTION. A LEARJET (MIL) WAS DEPARTING HIF CLBING TO 9000. A DC-9 WAS INBOUND TO SLC DURING AN ARR BANK AT 10000. TFC WAS HVY AND FREQ CONGESTED. TFC WAS EXCHANGED. AFTER THE DC-9 HAD PASSED THE LEARJET, THE DC- 9 ADVISED HE'D HAD AN RA AND HAD CLBED. I LOOKED AND OBSERVED THE DC-9 AT 10600 FT. TFC FLOW WAS AFFECTED AS THE DC-9 WAS A LITTLE HIGH AS HE PASSED THE SLC ARPT.
