[3] As the senior member of the Chief State Council, the Yeonguijeong participated in the administration of general government affairs alongside the Jwauijeong and Uuijeong.

In 1400, the second year of his reign, King Jeongjong reformed the Dopyeonguisasa (도평의사사; 都評議使司, also known as the Privy Council),[5] which was previously the supreme administrative body of the Goryeo dynasty, to the Uijeongbu.

[3] Until April 1436, the 18th year of Sejong the Great's reign, Jwauijeong and Uuijeong concurrently served as Panijosa (判吏曹事) and Panbyeongjosa (判兵曹事) respectively, so that they governed personnel affairs of yangban (the literary and military nobility).

Yeonguijeong continued to exist as an honorary post, and so only managed to contemplate and adjust diplomatic documents or re-examine the cases of condemned people.

[3] When Prince Suyang usurped the place of his nephew, King Danjong, the function of Yeonguijeong was relegated to its previous powerless position.

This was because when the King Sejo was still a prince, his actions were greatly restricted by his political rivals, Yeonguijeong, Hwangbo In and Jwauijeong, Kim Chongsŏ.

So the power of Yeonguijeong tended to be increased or decreased, depending on the political atmosphere of the times, such as the degree of the king's power, the relationship between Uijeongbu and Yukjo, the establishment of Bibyeonsa (備邊司; Border Defense Command[16]), the later administration of Kyujanggak (the Royal Library), the conflicts between political parties, and the advancement of "in-law government" (勢道政治, Sedo jeongchi[17]), among others.
