The upper house consisted of seventy-two members, the first purchasers of 5,000 acres or more in the colony. The lower house consisted of smaller landowners. It is important to mention that this advanced system of representation still lacked social equality in representation. Besides, it created as a complement four different branches in the provincial Council: a committee of plantations, "to situate and settle cities, ports, and market towns, and high-ways, and to hear and decide all suits and controversies relating to plantations," a committee of justice and safety, "to secure the peace of the Province, and punish the mar-administration of those who subvert justice to the prejudice of the public, or private, interest," a committee of trade and treasury, which, "shall regulate all trade and commerce, according to law, encourage manufacture and country growth, and defray the public charge of the Province," and, a committee of manners' education, and arts, that "all wicked and scandalous living may be prevented, and that youth may be successively trained up in virtue and useful knowledge and arts." It also granted the governor veto power in the legislative process. Moreover, it included an amendment process where six-sevenths of legislative branch and the governor could approve change. Furthermore, the Frame pioneered the idea that unconstitutional laws should be nullified. Additionally, this Charter of Liberties guaranteed free and fair trial by jury for all, justice in imprisonment and free elections. This guarantee gave Indians in trials with colonists, a jury composed of half Native Americans. .
In 1701, the Pennsylvania assembly started resisting Penn's proprietary authority and governance. Thus, he passed a new Frame called the Charter of Privileges enhancing the colony's governing. Thus, the new Frame strengthened the assembly's power, and gave it more constitutional parliamentary privileges.
