His doctoral thesis for Kookmin University, "Effect of Proprioceptive Neuromuscular Facilitation (PNF) on Flexibility and Isokinetic Muscle Strength in Taekwondo Player", came to the attention of the public media in South of Korea as a "copy-and-paste" plagiarism.
There are a number of "copy-and-paste" paragraphs in introduction, literature review, and discussion section of the thesis.
In April 2012, the research ethics committee of the Kookmin University announced: "The research subject of the doctoral thesis by Moon Dae-sung and part of the purpose of the research of his thesis overlap with those of a doctoral thesis by a person surnamed Kim at Myongji University. Not only that but a significant portion of the writing in the introduction, the theoretical background and the arguments in the two theses are so identical that we concluded this goes beyond what is normally permitted by the academic community."
Minutes after the school’s announcement, Moon issued a statement to announce his departure from the ruling party.
In March 2014, Kookmin University officially canceled his Doctor of Philosophy. Moon launched a nullification lawsuit, which his opponents believe is a tactic to keep his seat in the International Olympic Committee as well as the ruling Saenuri Party.
