Something in the syllabus is not automatically a ruling. For example, Minor did not rule that “The word “citizen “ is often used to convey the idea of membership in a nation.”
The ruling of Minor was:
“Being unanimously of the opinion that the Constitution of the United States does not confer the right of suffrage upon any one, and that the constitutions and laws of the several States which commit that important trust to men alone are not necessarily void, we AFFIRM THE JUDGMENT.”
