Narrative:
At approximately 20 mins before departure; a ramp employee brought a net from the aft pit on aircraft X into the ready room and asked if we could fix it. The fitting on the stanchion was not repaired. After some searching it was determined that a new fitting was in in the full view of the window on the door in the foreman's office which was locked. There was also a svcable stanchion inside. It was then less than 10 mins prior to departure and it became obvious that relief would have to be sought through the MEL. I pulled up the MEL and it was noted that operations had to be called. I called them and asked if I could inoperative the affected portion or the whole pit. The way it read it was the affected portion. Since the other aircraft are divided into individual compartments; it sounded reasonable to me. That meant that they could still use the baggage loading system which is separated from the doorway and aft section by a net. After the plane had pushed back but had not yet moved; station operations called to make sure that it was deferred properly (as far as loading the aft pit). I called operations back and questioned him again. He read it again; and came to the same conclusion that I had (we were in concurrence) and the aircraft was allowed to leave. When I came to work that night; I was notified that the deferral was incorrect and that the pit should have remained empty. I feel that all ambiguity should be removed from the MEL. I believe the ambiguity could be removed by changing the word from 'affected' to 'entire' forward or aft cargo compartment.

Title: AN A320 WAS DISPATCHED WITH A PORTION OF THE AFT CARGO COMPARTMENT DEFERRED AS INOP DUE TO A MISSING NET. THIS DEFERRAL WAS INCORRECT AND REQUIRED THE ENTIRE CARGO COMPARTMENT NOT TO BE USED.
Narrative: AT APPROX 20 MINS BEFORE DEP; A RAMP EMPLOYEE BROUGHT A NET FROM THE AFT PIT ON ACFT X INTO THE READY ROOM AND ASKED IF WE COULD FIX IT. THE FITTING ON THE STANCHION WAS NOT REPAIRED. AFTER SOME SEARCHING IT WAS DETERMINED THAT A NEW FITTING WAS IN IN THE FULL VIEW OF THE WINDOW ON THE DOOR IN THE FOREMAN'S OFFICE WHICH WAS LOCKED. THERE WAS ALSO A SVCABLE STANCHION INSIDE. IT WAS THEN LESS THAN 10 MINS PRIOR TO DEP AND IT BECAME OBVIOUS THAT RELIEF WOULD HAVE TO BE SOUGHT THROUGH THE MEL. I PULLED UP THE MEL AND IT WAS NOTED THAT OPS HAD TO BE CALLED. I CALLED THEM AND ASKED IF I COULD INOP THE AFFECTED PORTION OR THE WHOLE PIT. THE WAY IT READ IT WAS THE AFFECTED PORTION. SINCE THE OTHER ACFT ARE DIVIDED INTO INDIVIDUAL COMPARTMENTS; IT SOUNDED REASONABLE TO ME. THAT MEANT THAT THEY COULD STILL USE THE BAGGAGE LOADING SYS WHICH IS SEPARATED FROM THE DOORWAY AND AFT SECTION BY A NET.

WHEN I CAME TO WORK THAT NIGHT; I WAS NOTIFIED THAT THE DEFERRAL WAS INCORRECT AND THAT THE PIT SHOULD HAVE REMAINED EMPTY. I FEEL THAT ALL AMBIGUITY SHOULD BE REMOVED FROM THE MEL. I BELIEVE THE AMBIGUITY COULD BE REMOVED BY CHANGING THE WORD FROM 'AFFECTED' TO 'ENTIRE' FORWARD OR AFT CARGO COMPARTMENT.
