In the case of Cherokee Nation v. Blackfeather in 1894, the U.S Supreme Court was tasked with resolving a dispute over land rights between the Cherokee Nation and individual members of their tribe, specifically those known as "intruders" who were non-Cherokee people living on tribal lands. The court ruled that while tribes have sovereignty over their own affairs, this does not extend to ejecting intruders from tribal lands without federal approval. This decision reinforced previous rulings which held that Native American tribes are "domestic dependent nations" under U.S law and therefore subject to federal authority in certain matters such as these. It also highlighted ongoing tensions around issues of tribal sovereignty and land rights within U.S legal frameworks.

Unfortunately, there is no available information or records on a U.S. Supreme Court case titled Cherokee Nation v. Blackfeather from 1894 to provide a summary of the dissenting opinion. It's possible that you may have misremembered the name or date of the case, as many cases involving Native American tribes were heard during this period in history.
