室町幕府においては、守護（守護大名）に対して、既存の大犯三箇条に加えて、苅田狼藉検断、使節遵行権、段銭徴収権などの広範な権利が付与されていたが、幕府御家人は、足利将軍家の威光を背景に守護使不入の特権を得て、守護からの段銭徴収を拒絶し、幕府からの段銭要求に対しても幕府への直接納付（京納）が認められて守護からの加重徴収の危険を免れる事を可能とした。
In the Muromachi bakufu, extensive rights were given to shugo (or shugo daimyo, shugo that became daimyo, which were Japanese feudal lords), such as Karita Rozeki Kendan (the shugo's right to suppress provincial warriors who entered shoen unlawfully to harvest rice, and to prosecute and convict them), Shisetsu Jungyo Ken (a right empowered to shugo to implement shisetsu jungyo, in which shugo who received orders from the bakufu sent jungyo-shi, emissaries, to a region and have them execute the orders) and Tansen Choshu Ken (a right to collect surtax), in addition to the existing Taibon Sankajo, but bakufu gokenin (an immediate vasal of the shogunate in the Kamakura and Muromachi through Edo periods) who had been granted the shugoshi-funyu privilege backed by the authority of the Ashikaga family positioned to accede to the shogunate, refused collection of tansen (surtax) from shugo, and responded to one from the bakufu as direct payment to the bakufu (known as kyono) was approved, which enabled them to escape from a danger of being surcharged by the shugo. - Wikipedia日英京都関連文書対訳コーパス
