In the Sangamon County Circuit Court, Lincoln files a bill for injunction in the case of Ball et al. v. Lockridge et al. Lincoln and John T. Stuart represent plaintiffs Japhet A. Ball, Smith Ball, John S. Ball, and David Black. The plaintiffs are suing Elijah H. Lockridge, Joseph Lockridge, and William A. Lockridge for an injunction to prevent them from executing two judgments against the plaintiffs. In the bill for injunction, Lincoln argues that the Lockridges do not hold the title to a sawmill and a lot that the Balls and Black purchased from them. The plaintiffs seek to stop payments to the defendants until or unless the defendants can prove that they hold a legal title to the property. Stephen A. Douglass, Stephen T. Logan, and John D. Urquhart represent the Lockridges. Bill for Injunction, filed 17 April 1839, Ball et al. v. Lockridge et al., Tokyo Lincoln Center, Meisei University, Tokyo, Japan.
