In the case of Dolan v. Jennings in 1890, the U.S Supreme Court was tasked with deciding on a dispute over land ownership. The plaintiff, Dolan, claimed that he had purchased a piece of property from one Mr. Smith who had obtained it through preemption rights under federal law. However, before transferring the title to Dolan, Smith died and his widow remarried to Jennings - who then claimed ownership of said property as part of his wife's inheritance from her late husband. The court ruled in favor of Jennings based on two key points: Firstly, at the time when Smith filed for preemption rights (which would have allowed him to purchase public lands), he did not meet all necessary requirements – specifically residing upon or cultivating these lands as stipulated by law; Secondly, even if Smith’s claim were valid despite this discrepancy (as argued by Dolan), since no formal transfer deed existed between him and Dolan prior to his death - legal possession remained with Mrs. Smith which subsequently passed onto her new husband after their marriage. Thusly establishing that mere verbal agreements without proper documentation are insufficient proof for claiming ownership under such circumstances.

In the dissenting opinion for Dolan v. Jennings, it was argued that the majority's decision failed to properly interpret and apply contract law principles. The dissenting justices believed that the plaintiff should not be allowed to recover damages because he had willingly entered into a contract with full knowledge of its terms and conditions. They contended that there was no evidence of fraud or coercion in this case, which would have justified voiding the contract or awarding damages to one party over another. Furthermore, they pointed out that both parties were experienced businessmen who understood what they were agreeing upon when signing their contracts. Therefore, according to these justices' interpretation of contractual obligations and responsibilities under common law rules, any losses incurred by either party as a result of fulfilling their contractual duties should be borne by them alone without seeking redress from courts unless clear proof exists showing violation of legal rights during formation or execution stages.
