The controller does not enforce business rules.

Business rules are enforced in the business logic layer.

The controller reside in presentation layer or service layer
or control layer.

Model is either the business logic layer or (better IMHO)
a facade for the business logic layer residing in
presentation layer or service layer
or control layer.
