Invalid court case (8)

I believe the answer is:

mistrial

(Other definitions for mistrial that I've seen before include "bad hearing" , "legal process going wrong" , "Court case invalidated by procedural error" , "Invalid hearing" , "Inconclusive or invalid court proceedings" .)

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