The JCR is guided by a Constitution which dictates the composition of the Executive Committee and the responsibilities of its officers to Christ's students. It also governs more mundane procedural matters and the nature of the relationship between the JCR and the College. Although wordy and a little dry in places, the Constitution is a crucial document which enshrines the rights of all Christ's students and ensures that the JCR Exec is held accountable for its actions. It is regularly updated and often undergoes major revisions to suit the changing needs of the Christ's student body.
