Ten men act together in passing a law (9)
I believe the answer is:
enactment
'a law' is the definition.
(I've seen this before)
'ten men act together in passing' is the wordplay.
'ten men act' anagrams to 'ENACTMENT'.
However, I'm not clear how this is indicated.
Can you help me to learn more?
(Other definitions for enactment that I've seen before include "validation" , "A played-out" , "Command" , "Process of passing a law" , "The passing of a bill into law" .)
