In the 1894 case of Bergemann v. Backer, the U.S Supreme Court ruled on a dispute involving property rights and inheritance laws. The plaintiff, Bergemann, was an heir to a piece of land in Wisconsin that had been purchased by his father from the defendant's (Backer) grandfather. After his father's death, Bergemann claimed ownership over this land but faced opposition from Backer who also asserted claim over it based on an alleged will left by her grandfather leaving all properties to her. The main issue before the court was whether or not there existed a valid will which could override existing property rights established through purchase agreements. The lower courts found no evidence supporting existence of such a will and hence upheld Bergemann’s claim as rightful owner. Upon appeal at the Supreme Court level however, it was determined that while there may have been no physical proof for existence of said will; testimonial evidence provided by witnesses familiar with its contents were sufficient enough to establish its validity under Wisconsin law. Consequently, despite having previously acquired legal title via purchase agreement; due process required recognition of testamentary dispositions made prior thereto - thus ruling in favor of Backer.

In the dissenting opinion for Bergemann v. Backer, it was argued that the court erred in its interpretation of the law and application to this case. The dissenting justices believed that there were significant issues with how evidence was handled during trial proceedings, which they felt had a direct impact on the outcome of the case. They also disagreed with majority's interpretation of certain legal principles related to contract law and property rights, arguing that these interpretations were inconsistent with established precedent. Furthermore, they expressed concern about potential implications for future cases if such an approach is allowed to stand unchallenged.
