Jury Instructions in Roberts v. Harkness, [Law papers].
Appears to be in Lincoln's hand.
Summary: Harkness gave Isaiah Roberts three promissory notes in 1834 totaling $1,080. Isaiah assigned the notes to Henry Roberts, who sued Harkness in the Peoria County Circuit Court after Harkness failed to pay. Harkness argued that Roberts for $1,440 sold him an idea for an invention to manufacture bricks. Harkness refused to pay because he discovered that the invention was useless, which broke the consideration of the promissory notes. The court granted a change of venue to Tazewell County Circuit Court, and Harkness retained Lincoln. The first jury failed to reach a verdict, but a second jury found for Harkness. Roberts motioned for a new trial, but the court overruled the motion.
