In the Merritt v. Cameron case of 1890, the U.S Supreme Court ruled on a dispute involving land ownership in Washington D.C. The plaintiff, Merritt, claimed that he had purchased a piece of property from one Mr. Barry and later discovered that it was already mortgaged to Cameron by Barry's wife before his death. When Mrs. Barry died intestate (without leaving a will), her children inherited the property and sold it to Merritt without disclosing its existing mortgage status. Merritt sued Cameron for not revealing this information during their transaction but lost at both trial court level and upon appeal at the Supreme Court due to lack of evidence proving fraud or misrepresentation on part of Cameron. The Supreme Court held that since there was no proof showing any fraudulent intent or concealment by either party involved in selling the property - neither by Mrs.Barry’s children nor by Mr.Cameron who held an earlier mortgage over it - they could not be held liable for damages sought by Merrit.

In the dissenting opinion for Merritt v. Cameron, it was argued that the majority's decision to uphold a lower court ruling in favor of Cameron failed to properly consider key aspects of contract law. The dissenting justices believed that there was sufficient evidence showing an agreement between both parties and thus, Merritt should have been entitled to compensation as per their agreement with Cameron. They contended that the majority had erred by not giving enough weightage to this contractual obligation and instead focusing on technicalities related to property rights which were less relevant in this case. Furthermore, they disagreed with the interpretation of certain legal principles used by the majority in reaching its conclusion.
