This Supreme Court case involved a dispute between two parties, appellants Dunlap and another, and respondents Dunlap and others. The appellants argued that the lower court had erred in its decision to grant an injunction against them from selling certain lands belonging to their father's estate. They claimed that they were entitled to sell these lands as part of their inheritance rights under Virginia law. However, the respondents contended that such sales would be detrimental to other heirs who had not yet received their share of the estate due to debts owed by it at the time of death. After considering both sides' arguments, the Supreme Court ultimately ruled in favor of the respondents on grounds that allowing any sale before all creditors were paid off could potentially harm those still waiting for payment from said estate.

In the case of Dunlap and Another v. Dunlap and Others, the Supreme Court had to decide whether a deed was validly executed by an individual who lacked mental capacity due to old age. The majority opinion held that since there were no witnesses present at the time of execution, it could not be proven that he had sufficient mental capacity when signing it. However, in his dissenting opinion Justice Story argued that although there were no witnesses present at the time of execution, evidence from other sources such as family members or acquaintances should have been considered in order to determine if he did indeed possess sufficient mental capacity when signing it. He further argued that even if this evidence was insufficient for establishing legal validity under common law principles then equity should still apply so as to uphold its validity given all circumstances surrounding its execution.
