Miller v. Todd, a parenting case between two parties who were never married, raised the issue of whether Supreme Court Rule 3 is unconstitutional because it treats married and unmarried parents differently for the purposes of an appeal. At the time, only parents who were married were entitled to a mandatory appeal from an initial determination of parental rights and responsibilities. A mandatory appeal provides that the case “shall be accepted by the supreme court for review on the merits.” Although an appeal from a final divorce decree or final decree on legal separation is a mandatory appeal, an initial determination of parental rights and responsibilities between unmarried parents was not.

In Miller v. Todd the Supreme Court declined to address the issue by declaring it moot. In other words, because the Supreme Court had accepted the father’s discretionary appeal for review, the issue was purely academic because he had not been harmed by having his appeal declined. The Court noted, however, that “any consideration regarding amending Rule 3 should be accomplished in accordance with the rule-making procedures set forth in Supreme Court Rule 51, thereby providing the public, the bench and the bar an opportunity to offer comments and suggestions.”

On April 4, 2014, the Supreme Court adopted new rules, including an amendment to Supreme Court Rule 3 that now provides a mandatory appeal for “the first final order issued in, or arising out of, a domestic relations matter filed under RSA Title XLIII (RSA chapters 457 to 461-A).” The comments to the new rules identify the change results from the claim raised in Miller v. Todd that “providing for mandatory review of appeals involving married parents but discretionary review of appeals involving non-married parents raises constitutional concerns."
