I think that's a pretty narrow interpretation of "deny".

Definition #2 of "deny" from reads "to refuse to agree or 
accede to: to deny a petition", but definition #3 reads "to withhold 
thepossession, use, or enjoyment of: to deny access to secret information".

I think returning NODATA falls under definition #3.
