New York Court of Appeals
John Walls, Respondents v. George Bailey, Appellant
May 28, 187249 N.Y. 464
Summary
The Court reversed the trial court's judgment, holding that evidence of a local plastering custom was admissible to interpret the ambiguous contract, that the custom was reasonable and could be part of the contract, and that the trial court erred in excluding the defendant's testimony on his knowledge of the custom, necessitating a new trial.
