Myers v. Fenn was a United States Supreme Court case in which the court held that an individual's right to vote is not dependent on whether or not they are a citizen of the state where they reside. The plaintiff, Myers, had been denied his right to vote in Pennsylvania because he was not a citizen of the state and argued that this violated his constitutional rights as outlined by Article IV Section 2 of the Constitution. The Supreme Court ruled unanimously in favor of Myers, holding that voting rights were independent from citizenship status and could therefore be exercised regardless if one was considered a "citizen" or "non-citizen". This decision established an important precedent for future cases involving voting rights and has since become integral to our understanding of civil liberties within America today.

In Myers v. Fenn, the Supreme Court was asked to decide whether a state court had jurisdiction over a case involving federal officers and their actions in executing orders from the President of the United States. The majority opinion held that it did not have such jurisdiction, as this would be an encroachment on executive power by judicial authority. Justice Field dissented from this ruling, arguing that while Congress has exclusive control over matters concerning military personnel and operations, there is no reason why state courts should not have concurrent jurisdiction with federal courts when it comes to civil suits against government officials for acts done under color of office or authority. He further argued that allowing states to exercise some degree of oversight in these cases would help ensure accountability among public servants and prevent abuses of power within the executive branch.
