Complete case dismissed, both male and female appealing (7)
I believe the answer is:
execute
'complete' is the definition.
(synonyms)
'case dismissed both male and female appealing' is the wordplay.
'case dismissed' means to look at the middle letters (the letters that encase the word are removed).
'both male and female' becomes 'sexes'.
'appealing' becomes 'cute' (I've seen this before).
The central letters of 'sexes' are 'exe'.
'exe'+'cute'='EXECUTE'
(Other definitions for execute that I've seen before include "Discharge" , "Complete - implement" , "Put to death - put into effect" , "Get it done" , "Inflict capital punishment upon" .)
