Alpha Theta was one of the first collegiate fraternities in the United States to break from its national organization over civil rights issues, and the first at the Greek-dominated Dartmouth College.

In 1951, while Dickey served as president of the college, the student body passed a resolution calling on all fraternities to eliminate racial discrimination from their constitutions.

On April 24, 1952, the members of the Dartmouth chapter voted unanimously to stop recognizing the racial clause in Theta Chi's constitution.

Subsequent owners used the candy shop as a dwelling and Theta Chi fraternity eventually bought it from J. V. Hazen in 1921.

John Trickey Jr. '33 T'34, past president of the chapter and a student at the Tuck School of Business, was elected to replace Moldenke.

In February 2011, the Alpha Theta House Corporation filed suit against a former treasurer, Bruce McAllister, alleging that he stole hundreds of thousands of dollars from the fraternity.

[15] In November 2011 McAllister, a former financial auditor at Dartmouth College, was indicted for wire fraud following an investigation by the United States Secret Service.

[16][17] McAllister was sentenced on November 26, 2012, in United States District Court in Burlington, Vermont, to eighteen months of imprisonment following his guilty plea to wire fraud.

U.S. District Judge William K. Sessions III also ordered that McAllister serve three years of supervised release after he completes his prison term and pay slightly more than $800,000 in restitution to Alpha Theta and the Meccawe Club.

McAllister's sentence was reduced due to a medical condition, which included bladder cancer, chronic obstructive pulmonary disease, and kidney blockage.
