CONSTITUTION*
Lawrence B. Solum**
In his book, America's Unwritten Constitution, Akhil Reed
Amar contends that to properly engage the written Constitution,
scholars and laymen alike must look to extratextual sources: among
them America's founding documents, institutional practices, and
ethos, all of which constitute Amar's unwritten Constitution. In
this Article, I argue that contemporary originalist constitutional theo-
ry is consistent with reliance on extraconstitutional sources in certain
circumstances. I establish a framework for revaluating the use of ex-
tratextual sources. That framework categorizes extratextual sources
and explains their relevance to constitutional interpretation (the
meaning of the text) and constitutional construction (elaboration of
constitutional doctrine and decision of constitutional cases). I con-
clude by applying the framework to a question posed by Akhil Amar:
Can vice presidents preside over their own trial upon impeachment?
A negative answer to this question is consistent with an originalist
constitutional theory that carefully cabins the use of extratextual
sources in constitutional interpretation and construction.
