The 2005 Christ Church Commemoration ball was the first to be held by that college for fifteen years because of an incident at the 1990 ball that led to the Governing Body suspending the ball and replacing it with an annual summer party until 2005. Until 1990 the three great Oxford choral foundations of Magdalen College (first year), New College (second year) and Christ Church (third year) held their "white tie" Commemoration Balls in consecutive years on a triennial basis, each being widely regarded as the most prestigious ball being held in Oxford in that year, but the 1990 incident at Christ Church upset the tradition as various other colleges claimed Christ Church's (third year) slot, and continue to do so after the Christ Church Ball was reinstated in 2005. The cancellation of Magdalen College's (first year) Commemoration Ball in 2015, and its reinstatement in the "New College" (second) year of 2016, completed the break with tradition.
