Take away dude misbehaving in front of court (6)
I believe the answer is:
deduct
'take away' is the definition.
(I know that take away can be written as deduct)
'dude misbehaving in front of court' is the wordplay.
'misbehaving' is an anagram indicator.
'in front of' is a charade indicator (letters next to each other).
'court' becomes 'ct' (abbreviation used in road names).
'dude' with letters rearranged gives 'dedu'.
'dedu'+'ct'='DEDUCT'
(Other definitions for deduct that I've seen before include "Remove" , "Withhold" , "Make a subtraction" , "Knock off" , "Subtract, take away" .)
