Fair point! (9)
I believe this is a double definition.
'fair' is the first definition.
(objective can mean fair or unbiased)
'point' is the second definition.
(thesaurus)
(Other definitions for objective that I've seen before include "relating to external phenomena" , "Purpose" , "for neither side" , "Unbiased - aim" , "Goal, intent" .)
'fair point' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for true that I've seen before include "comfortable" , "Exact, factual" , "Honest - expression of agreement" , "Real or correct" , "Accurate, factual" .)
