Tax Payments Made Voluntarily Cannot Be Recovered Under a Mistake of Law Theory/Supreme Court Should Not Raise a “Non-Subject-Matter-Jurisdiction” Defense Sua Sponte

The Third Department determined Supreme Court properly denied petitioner’s request for a refund of real estate taxes paid re: optic cable installations located on private rights-of-way because petitioner had not protested the tax payments and made them voluntarily.  In addition, the court noted that the court should not have raised the statute of limitations defense sua sponte because the defense did not implicate subject matter jurisdiction:

… [U]nless subject matter jurisdiction is implicated, a court should not raise an issue sua sponte when a party is prejudiced by its inability to respond … . Here, because respondent Essex County failed to raise the statute of limitations as an affirmative defense in a pre-answer motion to dismiss or in its answer (see CPLR 3211 [a] [5]; [e]; 7804 [f]), it was improper for Supreme Court to raise it sua sponte … . * * *

… [W]e find no reason to disturb Supreme Court’s partial denial of the petition on the ground that petitioner failed to demonstrate that it paid the taxes involuntarily. To recover payments made under a mistake of law, as in the present case … , a taxpayer is required to show that the payments were made involuntarily … . This requirement ensures that governmental entities have notice that they may need to provide for tax refunds … . Here, petitioner fully paid all of the relevant taxes and offered no proof that it did so under protest or that such payments were otherwise involuntary … . Indeed, petitioner did nothing to indicate that its payments were involuntary until nearly 18 months after the final contested tax bill was paid, when petitioner submitted its RPTL 556-b correction applications … .
