What can stop a university from doing whatever they want and screwing students over in terms of accusing them of cheating, plagiarism, or a misunderstanding of professor authorization of essay re-submission in a second class, trying to take a student's degree or credit away after the course is completed/graduated with little evidence and no proof of circumstantial evidence that truly happened at the time of the incident? Since they are private and go by their own rules and apparently there is no standard policy for how all universities are supposed to deal with issues.
This is in St. Catharines, Ontario, Canada.
Thanks.
