Meathook Reality

Suppose that a law school professor delegates their authority to post a syllabus to their secretary. Said secretary, instead of posting the current term’s material, posts the previous term’s material, which includes an incorrect reading assignment. This being the first day of classes, students have very little reason to believe that assignment is incorrect, and spend much of their weekend preparing for review of material and briefing cases.

Is the teacher liable for the time “wasted"? Is the secretary?

Do the students have any civil redress?
