Why was clause 61 left out of later versions of Magna Carta?

Clause 61 of the 1215 Magna Carta established a "form of security" by tasking 25 barons with ensuring the preservation of the charter's enumerated rights and liberties. This clause effectively authorized subjects to declare war on their king if he failed to uphold the agreement.12

When the charter was reissued in 1216 by the council of the young King Henry III, this clause—along with others deemed temporary, political, or restrictive to the crown's ability to raise funds and forces—was omitted. The council sought to stabilize the realm and recall rebellious barons to their allegiance, and they viewed the "security clause" as an impediment to royal authority. Rather than replacing the clause, the council postponed the omitted matters for future consideration, though they were never reinstated in later versions of the document.3
