Michels v. Olmstead, 157 U.S. 198 (1895)
Michels v. Olmstead
Submitted December 4, 1894
Decided March 18, 1895
157 U.S. 198
If, in an action at law upon a written contract, oral evidence offered by the defendant that the writing signed by the parties was not intended as a contract nor understood by either party to be binding as such, is excluded
by the court, upon the plaintiffs objection, as incompetent to control the written contract, he is estopped, at the hearing of a bill in equity thereupon filed by the defendant for an injunction against the prosecution of the action at law, to object that the evidence was admissible at law only.
The case is stated in the opinion.
