NILES' WEEKLY REGISTER, Baltimore, March 20, 1819  Close to eight pages are taken up with what one website lists as number 3 of "The Ten Most Significant Supreme Court Decisions Of All Time" (#2 is Roe vs. Wade; #1 is the Dred Scott Decision).
This is the case of McCulloch vs. the state Maryland, the text headed: "Bank of the United States - In the Supreme Court of the United States", with the lengthy text containing the Chief Justice's opinion, he being John Marshall. This landmark decision concerns the right of Maryland to tax a branch of the federal bank operating within its borders.
This fundamental case established the following two principles: 1) that the Constitution grants to Congress implied powers for implementing the Constitution's express powers in order to create a functional national government and: 2) that state action may not impede valid constitutional exercises of power by the federal government.
Nice to have this report in a newspaper so close to Washington, D.C.
Sixteen pages, 6 1/4 by 9 1/2 inches, very nice condition.

As noted in Wikipedia, this title: "...(was) one of the most widely-circulated magazines in the United States...Devoted primarily to politics...considered an important source for the history of the period."
