Sui generis
A similar case that led to the use of the label "sui generis" is the relationship of New Caledonia relative to France, because the legal status of New Caledonia can aptly be said to lie somewhere between a French overseas collectivity and a sovereign nation. Although other examples of such status for other dependent or disputed territories may exist, this arrangement is unique within the French realm.
Fourth International
In the wake of the World Congress, the line of the International Leadership was generally accepted by groups around the world, including the U.S. SWP whose leader, James P. Cannon, corresponded with the French majority to support the tactic of entrism "sui generis". At the same time, however, Cannon, Healy and Mandel were deeply concerned by Pablo's political evolution. Cannon and Healy were also alarmed by Pablo's intervention into the French section, and by suggestions that Pablo might use the International's authority in this way in other sections of the Fourth International that felt entrism "sui generis" was not a suitable tactic in their own countries. In particular, minority tendencies, exemplified in Britain by John Lawrence and in the U.S. by Bert Cochran, to support entrism "sui generis" hinted that Pablo's support for their views indicated that the International might also demand Trotskyists in those countries adopt that tactic.
