The chief aim of the Constitution was to ensure the major role of the deputies in the Convention, which was seen as being the essential basis for political democracy. The Legislative Assembly was to be elected by direct vote cast for a single member, deputies were elected on receiving a simple majority of the votes cast, and the assembly would sit for one year. The executive council of 24 members was chosen by the Legislative Assembly from among the 83 candidates chosen by the departments on the basis of universal male

The plan also included a national judiciary. On May 30, the Convention agreed, at the request of Gouverneur Morris, "that a national government ought to be established consisting of a supreme Legislative, Executive and Judiciary". This was the convention's first move towards going beyond its mandate merely to amend the Articles of Confederation and instead produce an entirely new government. Once it had agreed to the idea of a supreme national government, the convention began debating specific parts of the Virginia Plan.

The other was intended to represent the states to such extent as they retained their sovereignty except for the powers expressly delegated to the national government. The Constitution provides that the approval of both chambers is necessary for the passage of legislation. First convened in 1789, the Senate of the United States was formed on the example of the ancient Roman Senate. The name is derived from the senatus, Latin for council of elders (from senex meaning old man in Latin). James Madison made the following comment about the Senate: "In England, at this day, if elections were open to all classes of people, 
Title: Legislative veto in the United States
Content:  Delegates to the Constitutional Convention of 1787 that drafted the U.S. Constitution considered and rejected proposals for a legislative veto designed to reconcile the states to the federal union. Edmund Randolph proposed that: "The National Legislature ought to be impowered [sic] . . . to negative all laws passed by the several States contravening in the opinion of the National Legislature the articles of Union." The provision became part of Alexander Hamilton's proposal for a new government based on national consolidation, all but eliminating state sovereignty.

The national legislature—or Congress—envisioned by the Convention embodied the key compromise of the Convention between the small states which wanted to retain the power they had under the one-state/one-vote Congress of the Articles of Confederation and the large states which wanted the weight of their larger populations and wealth to have a proportionate share of power. The upper House—the Senate—would represent the states equally, while the House of Representatives would be elected from districts of approximately equal population. The Constitution itself called for ratification by state conventions specially elected for the purpose, and the Confederation Congress 
Title: Constitutional Convention (United States)
Content:  On May 31, the delegates discussed the structure of Congress and how its members would be selected. The division of the legislature into an upper and lower house was familiar and had wide support. The British Parliament had an elected House of Commons and a hereditary House of Lords. All the states had bicameral legislatures except for Pennsylvania. The delegates quickly agreed that each house of Congress should be able to originate bills. They also agreed that the new Congress would have all the legislative powers of the Confederation Congress and veto power over state laws. There was some opposition to the popular election of the lower house or House of Representatives. Elbridge Gerry of Massachusetts and Roger Sherman of Connecticut feared the people were too easily misled by demagogues and that popular election could lead to mob rule and anarchy. Pierce Butler of South Carolina believed that 
Title: History of the United States Senate
Content:    The United States Senate is the upper chamber of the United States Congress, which along with the United States House of Representatives—the lower chamber—comprises the legislative branch of the federal government of the United States. Like its counterpart, the Senate was established by the United States Constitution and convened for its first meeting on March 4, 1789 at Federal Hall in New York City. The history of the institution begins prior to that date, at the 1787 Constitutional Convention, in James Madison's Virginia Plan, which proposed a bicameral national legislature, and in the Connecticut Compromise, an agreement reached between delegates from small-population states and those from large-population states that in part defined the structure and representation that each state would have in the new Congress.

Content:  The Convention was following the Randolph Plan for an agenda, taking each resolve in turn to move proceedings forward. They returned to items when overnight coalitions required adjustment to previous votes to secure a majority on the next item of business. June 19, and it was Randolph's Ninth Resolve next, about the national court system. On the table was the nationalist proposal for the inferior (lower) courts in the national judiciary. Pure 1776 republicanism had not given much credit to judges, who would set themselves up apart from and sometimes contradicting the state legislature, the voice of the sovereign people. Under the precedent of English Common Law according to William Blackstone, the legislature, following proper procedure, was for all constitutional purposes, "the people." This dismissal of unelected officers sometimes took an unintended turn among 
Title: Constitutional Convention (United States)
Content:  The Virginia Plan called for the unicameral Confederation Congress to be replaced with a bicameral Congress. This would be a truly national legislature with power to make laws "in all cases to which the separate states are incompetent." It would also be able to veto state laws. Representation in both houses of Congress would be apportioned according either to quotas of contribution (a state's wealth as reflected in the taxes it paid) or the size of each state's non-slave population. The lower house of Congress would be directly elected by the people, while the upper house would be elected by the lower house from candidates nominated by state legislatures.

Content:  Parliament. The U.S. adopted the Articles of Confederation, a declaration that established a national government with a one-house legislature. Its ratification by all thirteen colonies gave the second Congress a new name: the Congress of the Confederation, which met from 1781 to 1789. The Constitutional Convention took place during the summer of 1787, in Philadelphia. Although the convention was called to revise the Articles of Confederation, the intention from the outset for some including James Madison and Alexander Hamilton was to create a new frame of government rather than amending the existing one. The delegates elected George Washington to preside over the convention. The result of the convention was the United States Constitution and the replacement of the Continental Congress with the United States Congress.
