Narrative:
Radar controller trying to provide too much service to all eastbound traffic, getting everybody to their requested altitudes and lined up for next sector. He overlooked wbound traffic at FL310 and climbed an eastbound aircraft from FL290 to FL330. By the time we realized the situation, we lost separation.

Title: A CTR RADAR CTLR CLBED AN ACR ACFT THROUGH AN OCCUPIED ALT DURING A BUSY SESSION RESULTING IN LTSS.
Narrative: RADAR CTLR TRYING TO PROVIDE TOO MUCH SVC TO ALL EBOUND TFC, GETTING EVERYBODY TO THEIR REQUESTED ALTS AND LINED UP FOR NEXT SECTOR. HE OVERLOOKED WBOUND TFC AT FL310 AND CLBED AN EBOUND ACFT FROM FL290 TO FL330. BY THE TIME WE REALIZED THE SIT, WE LOST SEPARATION.
