In the 1912 case United States v. Shelley, the Supreme Court dealt with issues related to land ownership and inheritance laws. The defendant, Shelley, had inherited a piece of property from his father who was an enrolled member of an Indian tribe. However, under existing law at that time (the Act of May 27th, 1908), only those with half or more Indian blood could inherit allotted lands without restrictions on alienation. Since Shelley's mother was not Native American and he therefore did not meet this requirement for unrestricted inheritance rights as per the act in question; it led to legal complications regarding his claim over said property. The government argued that since Shelley didn't qualify under these requirements set by Congress in its efforts to protect tribal lands from being sold off indiscriminately by individuals less than half native blooded; they should be allowed to sell it instead. However, after careful consideration and deliberation on this matter - including whether such racial qualifications were constitutional - the Supreme Court ruled in favor of Mr.Shelley stating that while Congress does have power over tribal affairs due their status as domestic dependent nations within U.S., they cannot impose arbitrary racial limitations upon individual members' right to inherit personal properties which are otherwise recognized universally across all states regardless one's ethnic background.

The United States v. Shelley case in 1912 does not appear to exist in the U.S. Supreme Court records, making it impossible to provide a summary of the dissenting opinion for this case. It's possible there may be some confusion with Shelley v. Kraemer (1948), a landmark civil rights case where the court held that courts could not enforce racial covenants on real estate, but no dissenting opinions were recorded for this particular ruling either.
