John Jackson, the plaintiff in error, brought a case against Samuel Hale, George C. Many and John V. Ayer to the Supreme Court of the United States. The dispute was over an agreement between Jackson and Hale that stated if Jackson paid $1,000 for certain lands then he would receive title to them from Hale. However when it came time for payment there were complications as Many had already obtained a mortgage on those same lands from Ayer prior to any agreement with Jackson being made. This led to confusion as both parties believed they had rightful claim over these properties which resulted in this case being heard by the Supreme Court of the United States where it was determined that since no legal action was taken by either party before their respective agreements were made then neither could be held liable or have any rights granted upon these properties until one took precedence over another legally through court proceedings or other means outside of verbal contracts alone.

In the case of John Jackson v. Samuel Hale, George C. Many, and John V. Ayer, the dissenting opinion argued that a contract between two parties should not be voided due to an alleged mistake in one party's understanding of its terms if there is no evidence that either party was aware of this mistake at the time they entered into it. The dissent further argued that even if such a mistake had been made by one or both parties, it would still be unfair to void their agreement without any proof as to who was responsible for making said error or how much each side knew about it when they agreed upon its terms. Finally, the dissent maintained that since neither party could prove which individual was responsible for any misunderstanding regarding their contract's provisions nor demonstrate what knowledge each possessed when entering into it - then justice demanded upholding their agreement and allowing them both to benefit from its execution according to its original intent and meaning as written down on paper
