This Supreme Court case involved a dispute between Henry Brewer, the lessee of certain lands in Pennsylvania, and Jacob and Daniel Blougher. The Bloughers had purchased the land from its owner but were unaware that it was already leased to Brewer. When they attempted to take possession of the property, Brewer sued them for trespass. The lower court found in favor of the Bloughers on grounds that their title was superior to any leasehold interest held by Brewer. On appeal however, the Supreme Court reversed this decision finding that as long as a tenant holds legal possession of land under an unexpired lease he has priority over subsequent purchasers who are not aware or informed about such leases. As such, they ruled in favor of Henry Brewer and ordered damages be paid for his loss due to trespass committed by Jacob and Daniel Blougher

In this case, the plaintiff in error (lessee of Henry Brewer) argued that a deed given to him by Jacob Blougher and Daniel Blougher was invalid because it had not been properly acknowledged before a justice of the peace. The Supreme Court disagreed with this argument, finding that there was sufficient evidence to prove that the deed had been validly executed. In his dissenting opinion, Justice Catron argued that although there may have been some evidence indicating validity of execution, it did not meet all requirements necessary for such an instrument under Pennsylvania law. He further noted that even if these requirements were met at one point in time they could be rendered void due to subsequent events or changes in circumstances surrounding them. Therefore he concluded that since no proof existed as to when and where the deed was actually executed or whether any witnesses were present at its signing then it should be considered null and void according to Pennsylvania law.
