Justice Field delivered the dissenting opinion in Stewart v. Platt, arguing that the majority had misconstrued the law and failed to consider certain facts of record. He argued that under California's Civil Code, a married woman was not required to join her husband in conveying real estate unless she had an interest therein; thus, Mrs. Platt should have been allowed to convey her separate property without joining with Mr. Platt as co-grantor or otherwise being bound by his acts or liabilities on such conveyance. Furthermore, Justice Field noted that there were no allegations of fraud against either party and therefore it would be unjust for Mrs. Platt to suffer any loss due solely to Mr. Platts' negligence in failing properly execute a deed of trust securing payment of his debt prior to executing a deed conveying title from himself and wife jointly as grantors when he knew they held separate interests in said property which could only be conveyed by them separately if at all . In conclusion, Justice Field believed that since both parties acted honestly throughout this transaction then neither should suffer any detriment because of their respective mistakes concerning execution of deeds transferring title between themselves alone or together with others
