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.
