Breaking a rule or law (9)

I believe the answer is:

breaching

'breaking a rule or law' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for breaching that I've seen before include "Breakers are" , "Breaking a rule or law" , "Transgressing, rules say" , "Breaking or failing to observe a law" .)

I've seen this clue in the Irish Times (Simplex) and The Irish Times.
