Narrative:

The problem arose when the high altitude controller failed to stop the aircraft at the coordinated altitude (coordination was done 3 times). I, as the super high altitude controller, failed to catch the mistake on initial contact with the aircraft. As soon as I realized the aircraft was assigned a higher altitude, I tried to stop him, and descend him back down. Separation was lost while trying to do this.

Title: ACFT WAS CLIMBED THROUGH ALT OF ANOTHER ACFT. LESS THAN STANDARD SEPARATION RESULTED.

Narrative: THE PROBLEM AROSE WHEN THE HIGH ALT CTLR FAILED TO STOP THE ACFT AT THE COORDINATED ALT (COORD WAS DONE 3 TIMES). I, AS THE SUPER HIGH ALT CTLR, FAILED TO CATCH THE MISTAKE ON INITIAL CONTACT WITH THE ACFT. AS SOON AS I REALIZED THE ACFT WAS ASSIGNED A HIGHER ALT, I TRIED TO STOP HIM, AND DESCEND HIM BACK DOWN. SEPARATION WAS LOST WHILE TRYING TO DO THIS.
