Narrative:
This flight was dispatched with the following MEL (captain and first officer RA display system inoperative -- 3345D) which is a non-dispatch item. Approximately 10 mins prior to landing; the maintenance controller called me to notify me that this was incorrectly deferred and that it should be deferred as a dispatch item which makes the TCAS system totally inoperative. Furthermore; the maintenance controller asked for my last name to defer this item to help correct or hide the fact that it was incorrectly deferred. Incorrect deferrals are not getting the attention they need. If you have any questions regarding intent; just pull the tapes.
