Dismiss Parisian from law officer's team, lacking heart (6)
I believe the answer is:
depose
'dismiss' is the definition.
(I've seen this before)
'parisian from law officer's team lacking heart' is the wordplay.
'parisian from' becomes 'de' ('from' in French).
'law officer's team' becomes 'posse' (posse can mean a legal team).
'lacking heart' means to remove the middle letters.
'posse' with its centre removed is 'pose'.
'de'+'pose'='DEPOSE'
(Other definitions for depose that I've seen before include "Set down" , "Oust from throne" , "Attest and force off a throne" , "Dismiss" , "Remove from power or testify on oath" .)
