In the 1891 case of White v. Rankin, the United States Supreme Court addressed a dispute over land ownership in Texas. The plaintiff, White, claimed that he had purchased a tract of land from one John Henry Brown in good faith and without knowledge of any competing claims to the property. However, it was later revealed that this same parcel had previously been granted by Mexico to another man named Juan Moya before Texas became part of the U.S., and subsequently sold to Rankin who then sued for possession. The court ruled against White on grounds that under Mexican law at time when Moya received his grant (which must be respected according to Treaty of Guadalupe Hidalgo), only Mexican citizens could own land; thus making Brown's sale invalid as he wasn't rightful owner due to not being recognized as such by Mexico when acquiring it initially from Moya's heirs who were non-citizens themselves too hence couldn't inherit legally either way.

The dissenting opinion in the case of White v. Rankin, 1891, argued that the majority's decision was incorrect because it failed to consider important aspects of property law and contract rights. The dissent emphasized that a mortgage is not an absolute conveyance of title but rather a lien or security for debt. Therefore, when Mr. White paid off his debt to Mrs. Rankin, he should have regained full ownership over his property without any further obligations towards her heirs or assigns as per their agreement stipulated in the deed of trust which was signed by both parties involved in this case; hence there shouldn't be any foreclosure proceedings against him initiated by them later on after Mrs.Rankin's death . Furthermore, they also pointed out that even if one were to argue about possible interests held by other parties due to inheritance laws applicable at that time , these would still need proper legal documentation supporting such claims before being considered valid under court jurisdiction - something which wasn't presented during trial proceedings thereby making its consideration irrelevant while passing judgement on this matter.
