Narrative:

When we were switched to tower, they said 'cleared to land runway 14R, hold short runway 27L.' I replied 'cleared to land runway 14R, unable hold short.' the controller then said 'cleared to land runway 14R.' the controller then cleared an aircraft to take off on runway 27L. I stopped the aircraft prior to the intersection, while the other aircraft was about 50 ft over the runway. I said 'I told you unable hold short.' the controller said 'roger.' either he didn't hear me say 'unable' or he ignored it. This could have had serious implications -- particularly if we blew through, balked the landing, or if he rejected his takeoff.

Original NASA ASRS Text

Title: B727 FLC REJECTS LAHSO AT ORD BUT CTLR IGNORES THE UNABLE.

Narrative: WHEN WE WERE SWITCHED TO TWR, THEY SAID 'CLRED TO LAND RWY 14R, HOLD SHORT RWY 27L.' I REPLIED 'CLRED TO LAND RWY 14R, UNABLE HOLD SHORT.' THE CTLR THEN SAID 'CLRED TO LAND RWY 14R.' THE CTLR THEN CLRED AN ACFT TO TAKE OFF ON RWY 27L. I STOPPED THE ACFT PRIOR TO THE INTXN, WHILE THE OTHER ACFT WAS ABOUT 50 FT OVER THE RWY. I SAID 'I TOLD YOU UNABLE HOLD SHORT.' THE CTLR SAID 'ROGER.' EITHER HE DIDN'T HEAR ME SAY 'UNABLE' OR HE IGNORED IT. THIS COULD HAVE HAD SERIOUS IMPLICATIONS -- PARTICULARLY IF WE BLEW THROUGH, BALKED THE LNDG, OR IF HE REJECTED HIS TKOF.
