Kanezane KUJO (the sixth generation descendant of Michinaga), who was involved in the establishment of shinsei in Jisho and Kenkyu eras as a minister and Sekkan (regents and advisers), often insisted that it was fundamental for the establishment of seifu (an official code of new laws issued by Daijokan, Great Council of State) or shinsei to "follow the example of Choho" (articles dated April 23 and June 5, 1178 of "Gyokuyo") and it follows that even two hundred years after the Choho era it was widely believed in the court noble society that Chohogannenrei should be a starting point for shinsei and that kugeho (laws issued by the imperial court) in the medieval period was greatly influenced by such a belief.
治承・建久の2度の新制の制定に大臣・摂関として関わった九条兼実（道長の6代目の子孫）は｢長保以後代々制符｣が制符（新制）策定の基本であるべきであると度々主張（『玉葉』治承2年4月23日・6月5日条）しており、長保から200年経た後世においても長保元年令が新制の出発点になるとする考え方が公家社会に広く存在し、中世公家法に対して強い影響を与えたことが分かる。
