Court finally finds nothing within the law (7)
I believe the answer is:
solicit
'court' is the definition.
(I know that court can be written as solicit)
'finally finds nothing within the law' is the wordplay.
'finally' says to take the final letters.
'nothing' becomes 'o' (looks like zero - 0).
'within the law' becomes 'licit' (I've seen this in another clue).
The last letter of 'finds' is 's'.
's'+'o'+'licit'='SOLICIT'
(Other definitions for solicit that I've seen before include "Tout" , "Ask (someone) for something" , "Proposition" , "Ask (favour)" , "Make request (for business etc)" .)
