Trying to get judgement changed is attractive (9)
I believe the answer is:
appealing
'attractive' is the definition.
(similar in meaning)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for appealing that I've seen before include "Asking for donation to charity" , "Challenging a judgment" , "Taking a case to a higher court" , "Those wrongly convicted may be" , "Charming" .)
