Narrative:
The controller was relieved by a supervisor for normal relief. Later a handoff was taken by the supervisor (MD80) and vectored behind other aircraft to follow (T34). Both aircraft were established on final to NAS corpus with adequate separation. However; the closure rate was compressing to less than standard separation. The supervisor attempted to slow the MD80 but O no avail; less than standard separation occurred without visual separation. Finally; NAS corpus tower requested an emergency climb out for the MD80. The MD80 upon frequency change to the supervisor questioned the go around and re-sequence.

Title: CRP CTLR DESCRIBED CONFLICT AS SUPVR WORKING POSITION ALLOWED FASTER TFC TO OVERTAKE SLOWER TFC ON FINAL.
Narrative: THE CTLR WAS RELIEVED BY A SUPVR FOR NORMAL RELIEF. LATER A HDOF WAS TAKEN BY THE SUPVR (MD80) AND VECTORED BEHIND OTHER ACFT TO FOLLOW (T34). BOTH ACFT WERE ESTABLISHED ON FINAL TO NAS CORPUS WITH ADEQUATE SEPARATION. HOWEVER; THE CLOSURE RATE WAS COMPRESSING TO LESS THAN STANDARD SEPARATION. THE SUPVR ATTEMPTED TO SLOW THE MD80 BUT O NO AVAIL; LESS THAN STANDARD SEPARATION OCCURRED WITHOUT VISUAL SEPARATION. FINALLY; NAS CORPUS TWR REQUESTED AN EMER CLBOUT FOR THE MD80. THE MD80 UPON FREQ CHANGE TO THE SUPVR QUESTIONED THE GAR AND RE-SEQUENCE.
