application/resume question

Is it advisable to include your fraternity membership and offices held on a resume or application for graduate school if you either resigned from or were expelled from the chapter? I am going into my senior year and am relatively sure that I just don't have the energy to put another year into it so I think I won't be returning to the house, but I definitely want to include my membership and the numerous offices I held on my med school applications, and am not sure if it is advisable to do so if I either just resign or move out of house and get expelled (chapter policy calls for an expulsion vote to be held for any members who move out of house, and as I am not the most popular member due to my loud and confident personality I don't stand a chance of getting voted to remain a member if i move out hahaha). So my dilemma is, do I list all my fraternity involvement on my application since I know this will bolster my application, or is there too great of a risk that the med school would check with Nationals, find out that I resigned/got expelled, and actually end up hurting my application as a result?
