In 1866, Marcus Neff hired attorney John H. Mitchell to complete some legal business, but failed to pay Mitchell's bill. Mitchell sued and received a default judgment against Neff, with Neff's property sold at auction to pay the bill. Pennoyer purchased the land from Mitchell, who had purchased the land at the sheriff's auction, and later Neff became aware of the forced sale. Neff then sued Pennoyer to regain the property in a case that became the U.S. Supreme Court case of "Pennoyer v. Neff" that defined legal jurisdiction for citizens residing in different states. At the trial, federal judge and Pennoyer adversary Matthew Deady ruled in favor of Neff, with the Supreme Court affirming the decision in 1877. Pennoyer was compelled to give the land back to Neff, and the property became a part of the Willamette Heights neighborhood in later years.
