I hate to inform you of this, but unfortunately, the department just realized that the university did not grant me a full graduate faculty status. Therefore, I was technically not authorized to teach a PhD seminar. This means that you will not be able to count this class as satisfying your requirements and you will need to retake it again next Spring with a different instructor.
I understand that for some of you, this jeopardizes your chances of graduation and I am very sorry about that. I hope that you still enjoyed your experience and we can discuss your options further on Monday.
