[Advice issued in response to an inquiry from a member of the Division 5/9/2006]

Without in any way limiting the authority of the instructor under Systemwide Senate Regulation 542 or Davis Division Regulation 527, it is a reasonable exercise of the instructor's discretion to exclude a student from a course if the student has not satisfied the stated prerequisites, the prerequisites to the stated prerequisites, and so on.  That is, "inherited" prerequisites are enforceable by the instructor.  In this case the instructor may request that the Registrar drop the student from the course after providing notice to the student.
