The question propounded, by the Court of Appeals consists of a copy of the petition in a ease, with the exception of the formal parts, including a contract attached to the petition as an exhibit, and concludes with the inquiry: “Under the facts and circumstances set forth in the petition, did the defendant national bank have the power to make the above-stated contract?” The only question raised in the case is whether the trial court erred in “sustaining the general demurrer of the defendant and dismissing the petition of plaintiff.” A proper ruling upon the assignment of error on that judgment depends solely upon a determination of the question, “did the defendant national bank have the power to make the above-stated contract?” To answer that question is to decide the entire ease which involves a mixed question of law and fact; and under repeated rulings of this court, “where a certified question of law does not propound a distinct issue of law, but in effect calls for a decision of the whole case, this court need not . . answer it.” No unmixed question of law beifag presented, we do not answer the question propounded.
