In Ruesch v. Commissioner, 25 F. 4th 67 (2d Cir. 1/27/22), GS here, the Court affirmed the Tax Court's holding that the § 7345 proceeding was moot where the IRS withdrew the "seriously delinquent tax debt" certification to the Secretary of State. The Tax Court opinion is Ruesch v. Commissioner, 154 T.C. 289 (2020), TC here at Dkt #25 and GS here.
In addition to holding that the § 7345 proceeding was mooted by the withdrawal of the certification, the Tax Court also held (from the syllabus):
Held: We do not have jurisdiction, under IRC sec. 7345 or otherwise, to consider in this case petitioner's challenge to her underlying liability for the penalties.
Even if the Tax Court had jurisdiction to assess the validity of Ruesch's underlying debt, Ruesch had already received the only relief she could obtain under the statute, namely, reversal of her certification as an individual with "seriously delinquent tax debt." See 26 USC § 7345(e)(2). Since there was no further relief the Tax Court could have provided under the statute, and since the statute provided Ruesch's only claimed basis for relief, it should have determined that Ruesch's remaining claims were moot. n3
n3 We note that Ruesch may yet have the chance to challenge her underlying liability in Court. That liability is currently the subject of an IRS appeals process that has still to run its course. See 26 USC § 6320. After receiving a final determination through that process, Ruesch will be able, if necessary, to "petition the Tax Court for review of such determination (and the Tax Court shall have jurisdiction with respect to such matter)." Id. § 6330(d)(1); see id. § 6320(c). If Ruesch continues to object to the IRS's position regarding her underlying liability, she will eventually have her day in Court. For now, however, there is nothing further for our Court or the Tax Court to do.
