At the 1787 Constitutional Convention, a proposal to include the phrase, "new States shall be admitted on the same terms with the original States", was defeated. It was feared that the political power of future new western states would eventually overwhelm that of the established eastern states. Once the new Constitution went into effect, however, Congress admitted Vermont and Kentucky on equal terms and thereafter formalized the condition in its acts of admission for subsequent states, declaring that the new state enters "on an equal footing with the original States in all respects whatever." Thus the Congress, utilizing the discretion allowed by the framers, adopted a policy of equal status for all newly admitted states. With the growth of states' rights advocacy during the antebellum period, the Supreme Court asserted, in Lessee of Pollard v. Hagan (1845),. that the Constitution mandated admission of new states on the basis of equality.
