¶1This is an appeal from an order of the circuit court refusing probate to the will of Laura E. Dada, deceased. A will of later date was offered for probate, and the decision denying probate to this will was affirmed by this court in Lyon v. Dada, 111 Mich. 340 (69 N. W. 654). That later purported will contained a clause revoking all former wills. The question presented by this appeal is whether denial of probate to this will is res adjudicata upon the question of whether it revokes the former will.
¶2This question was before the court of Massachusetts in the early case of Laughton v. Atkins, 1 Pick. 535, where the subject is treated in an able and exhaustive opinion by Parker, C. J. The principles to be extracted from that case *396are that all persons interested in an estate are parties to the probate proceedings, and bound by them, and that the disallowance of a will in toto on the ground of undue influence amounts to a determination that the revocatory clause is ineffectual. This case was cited and followed in Rudy v. Ulrich, 69 Pa. St. 177 (8 Am. Rep. 238), and is cited and approved in Wallis v. Wallis, 114 Mass. 512. In the present case it was determined on the former issue that the entire will was void on the ground of undue influence. There was no attempt to probate any part of the will, nor was the determination confined to any single clause of the will. We think the case is within the principle of those cited. See, also, Dudley v. Gates, 124 Mich. 440 (83 N. W. 97).
¶3The judgment of the circuit court will be reversed, and an order entered admitting the will to probate. The appellant will be entitled to recover his costs, to be paid out of the estate.
