Narrative:

At cruise the captain's mcdu failed and the first officer's mcdu was intermittent. The decision was made after a conversation with maintenance control and dispatch to return to departure airport. During the conversation with maintenance and dispatch both parties kept telling the crew that we could reset circuit breakers (C/bs) in flight. We felt this was a clear change to our new joint operations policy. After telling maintenance we could not reset a C/B in flight they proceeded to tell us we could and that we just did not want to. After a long discussion we found that there was bold guidance in the flight manual that states specifically pilots are not allowed to reset a C/B in flight. Dispatch then suggested the captain use emergency authority to reset the C/B at which time an emergency did not exist. The captain and I declined the suggestion. The flight returned to iad uneventfully.

Title: An A320 flight crew refused to reset a popped circuit breaker in flight as directed by Maintenance Control; citing a specific bold print prohibition against doing so in the newly developed joint FOM for the two recently merged air carriers.
