If it was something really important to your chapter, then it probably needs to be called to the attention of your judiciary board so that the person can be formally reprimanded.(I'm assuming you have a J-board, I think most organizations do.) Usually each chapter has certain judiciary procedures that must be followed when disciplining a member. The steps that need to be taken should be outlined in chapter bylaws/rules & regulations manuals. If you don't have a copy, then someone on your executive board or an alumni advisory board member should have one. Good luck!
