If you've drunk the REST koolaid (or like me drained the entire pitcher :-) ) 
you should always be thinking of leveraging HTTP features as much as 
possible and that would mean using status codes.  I would suggest 400 
('Bad request')

An error message in the body is good for providing additional info to 
humans but the API of your web service should not depend on it in any way.
