Did ewe turn up outside department? Au contraire (6)

'did ewe turn' is the definition.
The definition suggests a past participle verb which matches the answer.

'up outside department? au contraire' is the wordplay.
I cannot really understand how this works, but
'up' is found in the answer.
'department?' could be 'd' (abbreviation eg in MOD Ministry of Defence) and 'd' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
