Citations to the Preamble
In reading through Bushrod Washington’s opinions, one practice of note was his citation of the Preamble as authority. For example, in a case involving a state law, he said something along the lines of “This law cannot be valid because the Constitution was meant to create a more perfect union.”
Makes me wonder if there’s a paper (perhaps already written) on the original public meaning of the Preamble. Or the way in which the Preamble was cited.
