Withdrawal is only allowed based on a case-by-case basis (e.g. medical reasons, extenuating family circumstances), and must be supported by documentary evidence such as a Medical Certificate or Certificate of Death). If you decide to pull out from the Pro Bono opportunity after you have been successfully balloted without a valid reason, you will be blacklisted. Students who are blacklisted will be denied applications for two months and be denied priority in the last year of graduation against non-graduating students.
