If you're a student at Cornell University and you're accused of misconduct, you should not speak to the school or others without taking the necessary precautions. Too much is at stake. Cornell University will have specific policies as to how the case will be addressed and adjudicated. Understanding and successfully navigating these policies is import key to success.
The specific policy that would apply is in part dependent upon the specific offense alleged. Is it a Title IX sexual misconduct case? Does the case involve alleged academic integrity or an academic misconduct charge? Or is it just a general disciplinary issue? Also, understanding that Cornell University, as with most schools, is often in a rush to judgment and can unfortunately not have an accused student's rights and interests in mind. That's why an experienced attorney-adviser can help navigate the process and can help potentially best allow for the most favorable outcome by protecting an accused student's rights and interests.
