Law and order broken by TNT menace (9)

I believe the answer is:

enactment

I'm a little stuck... Click here to teach me more about this clue!

'law' is the definition.
(I know that enactment is a type of law)

'order broken by tnt menace' is the wordplay.
'tnt menace' can be anagrammed to 'ENACTMENT'.
But, I am unsure how this is indicated.

'and' is the link.

Can you help me to learn more?

(Other definitions for enactment that I've seen before include "Command" , "Theatrical performance" , "Portrayal" , "Legal process" , "Law that's been passed" .)

I've seen this clue in The Irish Independent.
