Opinion by
The policy stipulates that the insurance under it shall begin at noon and expire at noon of the days named. Such an agreement is entirely lawful and, of course, becomes the special rule for the fixing of dates so referred to. But it is by no means clear that it is intended to apply as the rule for all computations of time under the policy. The object of the clause is to fix with precision the term covered by the insurance and thereby to avoid possible dispute on the fundamental basis of any liability for loss. The same reason does not apply with equal force to the question of time on collateral matters, such as the stipulated protection for five days of property removed on account of danger of fire, the sixty days after adjustment of amount when the loss is to become payable, or the five days’ notice of cancelation as involved here. The application of such a special rule for computation might be extremely inconvenient and doubtful, as for example if goods had been removed in this case to save them
But the other assignments must be sustained. The affidavit of defense sets up clearly and specifically in the established and approved form that defendant “ is informed, believes and expects to be able to prove ” that the plaintiff’s loss in respect of equipment was not $228,734 as claimed but did not exceed $60,000, and the amount of defendant’s liability, if liable at all, was not $2,099 as claimed in the statement but would not exceed $1,035. This was sufficient to prevent judgment and put the plaintiff to proof of the amount of its loss. The plaintiff relied on the appraisement, but that is never conclusive, and is not even evidence at all unless made so by the parties uniting in it. It gets its entire force from the joint act of the parties through their agents, and where it is ex parte and, though averred by plaintiff in his statement, is denied by defendant, it goes for nought and is not evidence at all either on the motion for judgment or at the trial.
But the court below was of opinion that by defendant’s refusal to join in the appointment of appraisers, coupled with a total denial of liability, defendant was estopped from disputing the amount of the loss as estimated by appraisers appointed by other insurance companies and by plaintiff, ex parte as regards this defendant. This was a serious error. There was no element of estoppel in such action. The policy provides that, in case of disagreement as to the amount of loss, it shall be ascertained by appraisers, and further that no action shall be brought on the policy until after compliance with all its requirements,
But it has been held that the condition of the policy as to appraisement before suit is in substance no more than an undertaking to refer to arbitrators to be chosen in the future, and therefore revocable. Suit by the insured without preliminary appraisement has been sustained because the agreement being revocable could not bind him: Mentz v. Ins. Co., 79 Pa. 478; Commercial Union Assurance Co. v. Hocking, 115 Pa. 407; Yost v. McKee, 179 Pa. 381. The same rule must apply to the other party to the contract, and therefore if the defendant company omits or refuses to join in an appraisement, its rights cannot be prejudiced thereby, and it certainly cannot be es-topped by a denial of liability from requiring that if its liability is established, the amount of it shall be proved by competent evidence.
The learned judge below refers to McCormick v. Ins. Co., 163 Pa. 184, but that case falls far short of sustaining the present judgment. .If a defendant by his action misleads the plaintiff as to a certain line of defense he may be estopped from bringing forward that defense at the trial, but he is not thereby estopped from requiring the plaintiff to prove the ground on which he is allowed to recover. The principles by which the subject of waiver by estoppel, in regard especially to insurance companies, is governed, were carefully considered and intended to be settled in Gould v. Ins. Co., 134 Pa. 570, and the authority of that case has been affirmed in Everett v. Ins.
Judgment reversed and procedendo awarded.
