Some flipping yob's appropriate court punishment (4)
I believe the answer is:
asbo
'punishment' is the definition.
(I've seen this before)
'some flipping yob's appropriate court' is the wordplay.
'flipping' says the letters should be written backwards.
'some' indicates a hidden word (some of the parts of the word are used).
'obsa' is hidden in the letters of 'yobs appropriate court'.
'obsa' back-to-front is 'ASBO'.
(Other definitions for asbo that I've seen before include "Acronym for a legal restraint" , "Award for bad behaviour?" , "Court restraining order" , "Court order to prevent bad behaviour" , "It restrains hooligan" .)
