Where does tenure lie?

Does the university have the right to fire tenured faculty in the case of the elimination of departments, or must it reassign faculty members? The fundamental issue is where does tenure lie- at the department level, the school level, or the university level? What sort of salary protections come with tenure; at what point does a pay cut for a tenured professor effectively constitute discharge? How might some form of post-tenure review be implemented? What are the sanctions for a negative review, and is the ultimate penalty dismissal?
