Pretext for absence (5)

I believe the answer is:

alibi

(Other definitions for alibi that I've seen before include "Defence against accusation - was seen elsewhere at the time" , "that gets him off the hook?" , "Defence against charge - was seen elsewhere" , "Legal proof of innocence" , "Excuse - plea of being elsewhere" .)

I've seen this clue in the Sydney Morning Herald.
