After the radical changes that took place in tournament structures in the late 1970s, a disillusioned Xavier left the IMCS in 1980 to form an independent referee's association, the OISMCS. To this day, the OISMCS is the approved officiating body for many national leagues. However, the IMCS refuses to recognise it as an international body. It is claimed that many high-ranking players actually prefer the traditional basis of the OISMCS to the modern approach of the IMCS.
