The newly revised National Sports Promotion Act will come into effect on Martch 28, 2016. This new law intends to integrate two main sports related institutions into one legal entity. In the result, new Korea Olympic Committee will be launched even though its exact name of entity has not yet been decided. This new KOC is bring some legal problems related with breach of the Olympic Charter. On the basis of such awareness, this paper deals with a legal status of the Olympic Charter and IOC, effect of Olympic Charter as a source of law, domestic meaning of the Olympic Charter in Korea, legal status of new Korea Olympic Committee, relationship between KOC and Olympic Charter, legal effect by infringement of the Olympic Charter, dispute resolution. On the basis of the above analysis, this paper tries to introduce a desirable solution to harmonize new KOC and its article of association with the Olympic Charter. In conclusion, it is difficult for IOC to be recognized legal personality in international law. The Olympic Charter is also hardly recognized as a source of law in international law. However, the Olympic Charter can be recognized as a soft law. Domestically, IOC can be dealt as a foreign corporation because IOC is a non-profit corporation body established in Switzerland and under Swiss law. Within such context, legal personality of IOC can be admissible according to Act on Private International Law in Korea. Basically, new KOC or its expected article of association are not expected to violate the Olympic Charter on the whole, as long as it will observe the Olympic Charter, especially §28.3 on quorum for voting. Korea should keep making an effort to observe the Olympic Charter in constituting and operating KOC.
