The small state delegates were alarmed at the plan taking shape: a supreme national government that could override state laws and proportional representation in both houses of Congress. William Paterson and other delegates from New Jersey, Connecticut, Maryland and New York created an alternative plan that consisted of several amendments to the Articles of Confederation. Under the New Jersey Plan, as it was called, the Confederation Congress would remain unicameral with each state having one vote. Congress would be allowed to levy tariffs and other taxes as well as regulate trade and commerce. Congress would elect a plural "federal executive" whose members would serve a single term and could be removed by Congress at the request of a majority of state governors. There would also be a federal judiciary to apply US law. Federal judges would serve for life and be appointed by the executives. Laws enacted by Congress would take precedence over state laws. This plan was introduced on June 15.
