In the Humphrey v. Tatman case of 1904, the U.S Supreme Court dealt with a dispute over land ownership in Oklahoma. The plaintiff, Humphrey, claimed that he had rightfully purchased a parcel of land from an individual who obtained it through the Homestead Act. However, Tatman argued that this sale was invalid because at the time of purchase, there were still restrictions on alienation under federal law due to previous treaties with Native American tribes which granted them rights to these lands. The court ruled in favor of Tatman stating that any transfer or sale made during this restriction period was void and therefore Humphrey did not have legal title to the property.

The Humphrey v. Tatman case does not have a publicly available dissenting opinion recorded in the annals of U.S Supreme Court history, making it impossible to provide a summary for such. It's important to note that not all cases will have dissenting opinions; these are typically provided when one or more justices disagree with the majority ruling and wish to express their differing viewpoints on legal interpretations and implications of the case at hand.
