Powell v. Maguire
California Supreme Court · 1872-01-05 · cited 17×
In Powell v. Maguire, the plaintiff alleged a pre-existing verbal agreement with the defendant to jointly obtain and operate a legislative franchise for a steam ferry between Vallejo and Mare Island, claiming he helped secure the 1866 grant in the defendant's name and was entitled to a half-interest, but the defendant built and operated the ferry alone after refusing to transfer any share. The trial court ruled for the plaintiff and ordered an accounting, but the Supreme Court reversed, holding that the agreement amounted at most to an unlaunched partnership with no joint operations or contributions by the plaintiff. The core reasoning was that public policy bars equitable enforcement of secret antecedent deals to divide a legislative franchise not disclosed to the granting body, as this could enable undisclosed combinations and improper influence; the plaintiff's remedy, if any, was limited to a contract action at law, and precedents like Miles v. Thorne were distinguished because they involved post-grant ratification and actual participation.
