The Twenty-seventh Amendment was proposed by the First Congress in 178
9 but not adopted until 1992, when Michigan became the thirty-eighth s
tate to ratify it. The history of the Twenty-seventh Amendment poses a
constitutional problem: Can a proposed amendment be ratified over a p
eriod of 202 years? Professor Paulsen argues that the amendment proces
s is best understood as a set of formal rules requiring ''concurrent l
egislative enactment '' of a Proposed amendment by a two-thirds majori
ty of Congress and three-fourths of the state legislatures. This model
assumes that the proposal and ratifications of a constitutional amend
ment continue to have legal force over time. Paulsen concludes that th
e Twenty-seventh Amendment is valid. Paulsen similarly argues that sta
te applications for a constitutional convention may be cumulated over
time. He maintains that applications reciting a ''purpose ''for which
a state seeks a convention, but not explicitly conditioned on the conv
ention being limited to consideration of a particular subject, should
be considered as applications for a ''general,'' not a ''limited,'' co
nvention. Paulsen concludes that Congress is currently obliged to call
a constitutional convention, unlimited in the amendment proposals it
may consider.
