In the case of Elder v. Horseshoe Mining and Milling Company in 1903, the United States Supreme Court was tasked with determining whether a mining company had unlawfully taken possession of a claim owned by another party. The plaintiff, Elder, alleged that he had been deprived of his rightful ownership to a mine located in Idaho due to fraudulent actions by the defendant, Horseshoe Mining and Milling Company. He claimed that they manipulated him into signing an agreement under false pretenses which transferred ownership rights to them without any compensation for him. The court ruled against Elder stating there was insufficient evidence proving fraud or deceit on part of the defendants. They found no proof showing that Elder did not understand what he was signing or that he signed it under duress or undue influence from others involved in this transaction. Furthermore, they noted even if such claims were true; it would be irrelevant as per law because once an individual signs a contract voluntarily (even if deceived), they are bound by its terms unless proven otherwise through legal proceedings.

The dissenting opinion in the case of Elder v. Horseshoe Mining and Milling Company argued that the majority's decision to uphold a lower court ruling, which found in favor of Horseshoe Mining and Milling Company, was incorrect. The dissent disagreed with the interpretation of mining law applied by both courts, arguing it did not adequately protect miners' rights or interests. They contended that under existing legislation, Elder should have been allowed to continue his work on an unpatented claim without interference from another party who had obtained a patent for adjacent land but had not yet begun operations there. This view held that granting such broad powers to patent holders could potentially stifle competition and innovation within the mining industry by discouraging independent prospectors from undertaking new explorations or developments out of fear they might be halted at any time due to overlapping claims.
