Dicky's exempt from ordinary jurisdiction (8)
I believe the answer is:
peculiar
This clue is a double definition.
'dicky's' is the first definition.
(both can mean unsound or unreliable)
'exempt from ordinary jurisdiction' is the second definition.
(exempt from the jurisdiction of the local diocese)
(Other definitions for peculiar that I've seen before include "Strange or eccentric, quite odd" , "Odd - individual" , "Unusual" , "Characteristic" , "I clear up, being odd" .)
