That's not the issue. The issue is whether administrators should tell professors what they can or can't mention in a class.
Suppose an administrator said that no economics course could mention Adam Smith ... or that no economics course could mention Karl Marx? Either way, it's a question of control over the content of courses.
Nevertheless, as a past chairman of our University's Academic Standards Committee, I can answer your question. The curricula are established by the University Faculty Senate, or a subset thereof: The Academic Standards Committee. The chief admninistrator is responsible to oversee that the curricula are followed. Putting non-scientific content, such as the super-naturalism of ID or creationism, into science courses violates the academic standards.
