Although this could have apparently produced a chigaihoken (extraterritoriality) area in the domains of shugo daimyo and seems to have caused an obstacle in ruling systems of the Muromachi bakufu, in fact, contrary to that, by tightening of the shugo-ryogoku system (the system that a shugo dominates a manor), it prevented shugo daimyo from executing ryogoku ichien shihai (ruling the whole region of the territory) and suppressed expansion of his power, and at the same time, the privileged gokenin class tried to maintain this privilege by increasing dependence on the bakufu powers, which helped the bakufu form support for political, economic, and military bases to confront the shugo daimyo.
これによって一見すると守護大名の領域に治外法権地域が生まれる事になり、室町幕府の支配系統に障害が生じたかのように見られるが、実態はそれとは反対で守護領国制の強化によって守護大名による領国一円支配を阻止してその勢力拡大を抑制するとともに、特権を受けた御家人層は幕府権力への依存を強めてこの権利を維持しようと図り、幕府にとっては守護大名に対抗するための政治的・経済的・軍事的な基盤を支える支持の形成に効果があった。
