Attorney initially rejected case for appeal (10)
I believe the answer is:
attraction
'appeal' is the definition.
(I've seen this before)
'attorney initially rejected case' is the wordplay.
'attorney' becomes 'att' (abbreviation for attorney).
'initially' indicates taking the first letters.
'case' becomes 'action' (synonyms).
The initial letter of 'rejected' is 'r'.
'att'+'r'+'action'='ATTRACTION'
'for' is the link.
(Other definitions for attraction that I've seen before include "Pull" , "Magnetic force" , "Draw, allure" , "Popular building/place" , "Interest" .)
