Taxi ride not involved in legal handover (11)
I believe the answer is:
extradition
'legal handover' is the definition.
'extradition' can be an answer for 'handover' (as in being extradited to another country). I'm not certain of the 'legal' bit.
'taxi ride not involved' is the wordplay.
'involved' indicates anagramming the letters (involved can mean confusing or complex).
'taxi'+'ride'+'not'='taxiridenot'
'taxiridenot' is an anagram of 'EXTRADITION'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for extradition that I've seen before include "Sending back" , "Return to original state" , "Suspect removal" , "Handing over of a criminal between nations" , "Surrender of fugitive for trial in another country" .)
