In the case of Hicks v. Knost in 1899, the U.S Supreme Court dealt with a dispute over land ownership and mineral rights in West Virginia. The plaintiff, Hicks, claimed that he had purchased the property from its original owner who held both surface and mineral rights. However, prior to this sale, part of these rights had been sold to another party (Knost), unbeknownst to Hicks at the time of his purchase. When Knost began mining operations on the property years later, Hicks sued for trespassing and damages. The court ruled in favor of Knost based on two primary factors: firstly because there was no evidence showing fraudulent intent or concealment by either party during their respective transactions; secondly due to "caveat emptor" principle - meaning it was Hick's responsibility as a buyer to ensure all aspects related to his purchase were satisfactory before finalizing it. This decision underscored an important aspect about real estate transactions – buyers must exercise due diligence when purchasing properties especially where complex issues like mineral rights are involved.

The dissenting opinion in Hicks v. Knost argued that the majority's decision was inconsistent with previous rulings of the court and violated principles of equity. The dissent contended that a judgment rendered by a state court should not be invalidated on grounds that it had been procured through fraud, unless there was clear evidence to support such allegations. It further asserted that even if fraudulent practices were involved, they did not necessarily affect the validity or fairness of the judgment itself. Therefore, according to this view, federal courts should refrain from interfering with judgments made by state courts unless there is compelling reason to do so - something which was lacking in this case as per their perspective.
