When the fraternity incorporated in 1909 it adopted a new constitution. The Harvard chapter immediately set-forth its views that the new constitution had been illegitimately enacted and had overly vested control in the professional leadership, undermining the ability of the chapters to democratically express themselves. Though a number of other chapters initially signaled support for the Harvard position, a proposed amendment to the new document failed. In 1915 the Harvard chapter stopped paying dues to the fraternity. A further shot across the bow of the international fraternity came when Harvard requested headquarters stop sending copies of the "Delta Upsilon Quarterly" because they "littered up the house". Open revolt came when the international fraternity tried to impose discipline on Harvard. Harvard responded by declaring it didn't recognize the authority of DU headquarters as Delta Upsilon had ceased to exist in 1909. Delta Upsilon sued its rebellious chapter whose leaders included toy heir F.A.O. Schwarz Jr. Following the courtroom triumph of the DU headquarters, it expelled the rebellious members and initiated a hand-picked pledge class to continue the chapter. Its victory was short-lived, though, as the recreated chapter itself voted to disaffiliate from Delta Upsilon. The secessionist group legally reconstituted itself as "the D.U. Club", taking the chapter roll book with them, and existed as a successful finals club for many decades on the Harvard campus. In 1995, the D.U. Club closed after an assault of a football recruit occurred at its clubhouse. The D.U. Club's alumni board voted to merge its alumni with the Fly Club.
