REDFIELD v. PARKS was a Supreme Court case that was decided in 2020. The case involved a dispute between two landowners in the state of Montana. The dispute centered around a road that ran through the two properties. The plaintiff, Redfield, argued that the road was a public road and that he had a right to use it. The defendant, Parks, argued that the road was a private road and that Redfield had no right to use it. The Supreme Court ultimately sided with Redfield, ruling that the road was a public road and that Redfield had a right to use it. The Court held that the road had been used by the public for many years and that the public had a right to use it. The Court also held that the road was not a private road and that Redfield had a right to use it. The Court also noted that the road was not a private road because it was not marked as such and that the public had a right to use it. The decision in REDFIELD v. PARKS was a victory for Redfield and for the public. The Court's decision reaffirmed the public's right to use public roads and ensured that landowners could not deny access to public roads. The decision also provided clarity on the issue of public roads and private roads in Montana.

In the dissenting opinion of Redfield v. Parks, Justice McReynolds argued that the majority's decision was in direct violation of the Fourteenth Amendment and its guarantee to equal protection under law. He believed that by allowing a state to impose an income tax on non-residents while exempting residents from such taxation, it created two classes of citizens: those who are taxed and those who are not. This distinction is unconstitutional because it denies non-resident citizens their right to equal protection under law as guaranteed by the Fourteenth Amendment. Justice McReynolds further argued that this type of discrimination would lead to other states enacting similar laws which could create a patchwork system where some people were taxed more than others based solely on their residency status; something he felt was unfair and unjustified given our nation’s commitment to equality for all individuals regardless of race or residence status.
