Fair June, dice, cigs, ales - not half! (8)
I believe the answer is:
judicial
'fair' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for judicial that I've seen before include "from the bench" , "Relating to a court of law" , "Relating to the application of the law" , "Of a judge" , "Of law courts or the administration of justice" .)
