Adopts a new stance and establishes law (6)
I believe the answer is:
enacts
'adopts' is the definition.
(I've seen this in another clue)
'a new stance and establishes law' is the wordplay.
'stance' can be anagrammed to 'ENACTS'.
But, I'm not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for enacts that I've seen before include "Appears" , "sanctions" , "Turns a bill into law" , "Passes formally into law" , "Establishes by law" .)
