In the 1897 case of Bacon v. The Poconoket, the U.S Supreme Court addressed a dispute over land ownership in Rhode Island. The plaintiff, Bacon, claimed that he had purchased land from an individual who was allegedly part of the Wampanoag tribe (referred to as "The Poconoket" in court documents). However, it was disputed whether this person had any right to sell tribal lands at all. Furthermore, there were questions about whether or not these lands were actually part of a reservation protected by federal law and thus exempt from such transactions. Ultimately, the Supreme Court ruled against Bacon's claim on two grounds: firstly because they found no evidence that his seller held any authority within their tribe; secondly because even if they did have such authority - which remained unproven - Native American tribes cannot alienate their own reservation lands without explicit Congressional approval.

The dissenting opinion in the case of Bacon v. The Poconoket is not available or was not recorded. This 1897 Supreme Court case involved a dispute over land ownership, with the plaintiff asserting that they had purchased the land from Native Americans who were its rightful owners. However, there are no records indicating any dissenting opinions issued by justices on this particular case.
