Appeal from a judgment of the district court affirming the findings of fact, conclusions of law, and order determining heirship filed by the probate court.

As in In re Estate of Pakarinen, 287 Minn. 330, 178 N. W. (2d) 714, the issue presented is the constitutionality of that provision of Minn. St. 525.172 which requires an illegitimate to produce an attested written declaration of paternity made by decedent as a condition to inheritance. Here, appellant, the illegitimate son of the decedent, seeks to inherit from decedent under the omitted-child provision1 of the Minnesota Probate Code without producing an attested written declaration of paternity made by decedent. For reasons discussed in In re Estate of Pakarinen, supra, we hold that the challenged provision of § 525.172 is not unconstitutional.

Affirmed.
