In the 1890 case of Ames v. Moir, the United States Supreme Court dealt with a dispute over land ownership in Kansas. The plaintiff, Ames, claimed that he had purchased the land from an individual who obtained it through a preemption claim under federal law. However, defendant Moir argued that this was invalid as the original owner did not meet residency requirements for such claims and thus could not legally sell it to Ames. The court ruled in favor of Moir on appeal after initially siding with Ames at trial level. The Supreme Court found that although there were discrepancies between state and federal laws regarding preemption rights (rights to settle public lands), these differences didn't affect this particular case because both required actual residence on claimed property - which hadn't been met by initial claimant according to evidence presented during trial proceedings. This decision underscored importance of meeting all legal criteria when claiming or purchasing property under specific provisions like preemption rights; failure to do so can result in loss of said property if challenged later on grounds of non-compliance with relevant laws.

The dissenting opinion in the Ames v. Moir case argued that the majority's decision was incorrect because it failed to properly interpret and apply existing laws regarding property rights. The dissent believed that Mr. Ames had a valid claim to the disputed land, as he had purchased it from its original owner who held legal title to it at the time of sale. They contended that any subsequent changes in ownership did not invalidate this initial transaction, and therefore Mr. Ames should retain his rights over the property despite later developments or claims made by other parties such as Mr. Moir.
