If there are serious red flags raised during the application process or from evaluations from the student’s law school, there could be problems. Serious criminal law issues could present a problem, as could allegations of sexual harassment or other bad behavior. If the bar examiners in a state believe that a lawyer has been untruthful or lacked candor in the application process, then there could be problems for that candidate. If a person had an issue with plagiarism or other form of academic dishonesty, that could be cause for concern. It is hard to generalize because these issues vary from state to state.
