Can Ratification of a constitutional amendment legally change a ruling of the US Supreme Court?

Yes, the ratification of a constitutional amendment can legally change a ruling of the U.S. Supreme Court. This is because amendments to the Constitution can modify or override judicial interpretations of constitutional provisions. For example, the 14th Amendment effectively overturned the Dred Scott decision by establishing citizenship and equal protection under the law for all individuals born in the U.S. Thus, while individual Supreme Court rulings are binding, the Constitution can be amended to reflect new legal standards or interpretations.
