Senior Grandmaster Phap Lu's Open Email Senior Master Phap Lu stated on October 22, 2002, in an Open email to Taekwon-Doists that,
"General Choi did not speak his last words with the constitution in mind. He spoke as a CREATOR of the art. When he was alive what he said was law, in death are his words are no longer valid?" It is here that he explains the background behind General Choi's reason for choosing Chang Ung as a successor. :
"That was why General Choi handpicked Mr. Russell MacLellan as the Senior Vice-president to fulfill the role as acting President if anything happened to General Choi. At this time Mr. Chang Ung’s name was never mentioned. Our beloved Founder still waited for his son to visit him at the hospital in Pyongyang, but his last hope TOTALLY vanished when the nine people visited Gen. Choi without his son’s presence in mid of June 2002 after the International Gen. Choi’s Cup in Ottawa, Canada...Since February 2002 there has been a recent rapid change in the political situation in both KOREAs. After General Choi was admitted to the hospital in North Korea, General Choi saw the light of unification in both TAEKWON-DO and North and South KOREAs. With Mr. Chang Ung’s I.O.C. experience, knowledge and talents, as well as his relationship with Mr. Ung Yong Kim, his various meetings with both North and South Koreans TaeKwon-Do Committees members, General Choi Hong Hi, handpicked Mr. Chang Ung as his successor before his departure. The sudden appearance of Mr. Chang Ung surprised much of the PRESENT CORE ITF MEMBERS as he was never spoken of by General Choi." :
"Our beloved Founder General Choi Hong Hi DID NOT PICK Mr. Chang Ung in favor of North Korea, but he picked him up as successor because OF THE PRESENT POLITICAL CLIMATE as well as his leadership qualities. This was the BRILLIANT FUTURE VISION of our beloved Founder and Father. If you were Mr. Chang Ung I believe that regardless of whether you were a Canadian, Italian, Korean or Argentinian you would be picked too. THAT IS OUR GENERAL CHOI, everything fits for Taekwon-Do. If it fits he would use it, because he believed that these were gifts from Heaven to him. Gen. Choi used to tell us that his Parents gave his name CHOI HONG HI and HEAVEN gave his name TAEKWON-DO. He was even afraid that nobody would know what Taekwon-do would be, he asked people to cover his coffin with the words TAEKWON-DO. I believe that whatever the outcome will be: IT IS THE LAST WISHES OF GENERAL CHOI HONG HI. We at least own him for these."'
Regarding the Legal Status of Chang Ung's ITF Shortly after Chang's ascension to the ITF presidency, the legality of the organization was put into question. However, these issues have since been resolved. She stated, "
I wish you would support Prof. and Dr. Chang Ung, and be with him with one mind and one will for the brighter future of the ITF". Chang was also the president of
International Martial Art Games Committee. Chang has been an advocate for Asia's third Winter Games, stating that it would help the development of winter sports in the region which are "still far behind" Europe and North America. In 2015, Chang resigned and was replaced by Ri Yong-son as the President of ITF. At the end of 2018 Ung ceased to be a member of the IOC retiring as per protocol after turning 80. ==Death==
