Narrative:
Upon completion of cockpit scan/inspection; the stall protection #2 cutout switch guard was found to not function; it did not spring back to the guarded position and stayed open unless closed manually. Maintenance control was contacted with the discrepancy write-up; maintenance control controller advised the captain several times that per director of maintenance this item does not affect airworthiness and to make it an 'information to maintenance' item. Upon arriving at ZZZ later that day; crew was advised by maintenance that this item was a grounding item and; therefore; it was illegal for maintenance control to tell the captain to make it 'information to maintenance;' and for the aircraft to have continued with this discrepancy.
