Journalist is getting to grips with court rulings (6)
I believe the answer is:
edicts
'rulings' is the definition.
(I've seen this before)
'journalist is getting to grips with court' is the wordplay.
'journalist' becomes 'ed' (short for editor).
'getting to grips with' indicates putting letters inside (one group of letters grips another).
'court' becomes 'ct' (abbreviation used in road names).
'is' placed around 'ct' is 'icts'.
'ed'+'icts'='EDICTS'
(Other definitions for edicts that I've seen before include "Decrees by authority" , "'Decrees, fiats (6)'" , "Orders proclaimed by authorities" , "'Decrees, orders (6)'" , "Official orders and decrees" .)
