On Supreme Court U.S. (or is it U. S.) Citations and the Supreme Court's Tariff Opinions (2/22/26; 2/23/26)

This blog entry is a bit of a detour from the domain of federal tax procedure. Specifically, this blog presents two more or less fringe disparate subjects. I divide the blog into two sections. The first is mundane: whether to space or not to space between U. and S. in Supreme Court citations? The second is a disjointed foray into the Supreme Court’s tariff opinions handed down Friday:  Learning Resources, Inc. v. Trump, 607 U. S. ___ (2026), here (Slip Op.).

To Space or Not  to Space in U.S. (or it is U. S.) Citations, that is the Question

For those who review Supreme Court opinions in all official formats (Slip Opinion, Preliminary Print, and Final), the opinions format the citation to the official reports with a blank between U. and S.—e.g., Loper Bright Enter. v. Raimondo,  603 U. S. 369 (2024), here (Preliminary Print). I had not learned to cite without the space and had not paid attention to the Supreme Court's format (with space) until today as I was reading the slip opinion in Learning Resources, Inc. v. Trump, 607 U. S. ___ (2026), here (Slip Op.). So, I asked ChatGPT and received the following answer (with my prompt, with citations omitted):

Prompt: Please cite me authorities (judicial and otherwise) that discuss the difference between the Supreme Court's citation of its decisions as "U. S." (with a blank between U. and S. and other authorities (mostly commentary but also Courts of Appeals and case reporters) foregoing the blank between U. and S.

Chat GPT Response: 

The U.S. Supreme Court officially cites its own decisions using "U. S." with a space between "U." and "S." in the United States Reports (e.g., 5 U. S. 137), while The Bluebook, Courts of Appeals, most legal commentary, and case reporters standardize "U.S." without the space. This distinction arises from the Court's unique style conventions versus modern citation guides like The Bluebook, which enforce no space between adjacent single capital letters per Rule 6.1(a).

Supreme Court Practice ("U. S." with space)

The Supreme Court itself uses spaced citations in its bound volumes of the United States Reports, reflecting historical typography from early volumes like Marbury v. Madison, 5 U. S. (1 Cranch) 137 (1803).8 This format appears consistently in official reporter headings and the Court's published opinions.

Other Authorities ("U.S." without space)

The Bluebook: Prohibits "U.S." with a space, mandating "U.S." for United States Reports (e.g., Roe v. Wade, 410 U.S. 113 (1973)); spaces are reserved for abbreviations like "S. Ct." (Rule 6.1(a) and Table T1).

Courts of Appeals and State Appellate Guidance: U.S. Courts of Appeals briefs require "U.S." without parallels or spaces (e.g., Roe v. Wade, 410 U.S. 113 (1973)). California Courts of Appeal cite as "450 U.S. 544." Washington Supreme Court style sheet specifies "__ U.S. __" without space in examples.

Tax Court (Lauber) Rejects Bullshit Syndicated Conservation Easement (BSSCE) Valuation Claim (2/19/26; 2/20/26)

Today, Judge Lauber called out yet another bullshit syndicated conservation easement (“BSSCE”). North Donald LA Property, LLC v. Commissioner, T.C. Memo. 2026-19 T.C. No. 24703-21, here, at # 476; TN here; and GS here [to come]).The BSSCE claimed a charitable contribution of $115,391,000. The flaw that swung the case against BSSCE was, as Judge Lauber held in the opening (Slip Op. p. 3):

We conclude here, as we did in J L Minerals, LLC v. Commissioner, T.C. Memo. 2024-93, at *3, that the valuation of the conservation easement “was an outrageous overstatement,” wholly untethered from reality. Employing the comparable sales method, as backstopped by the price actually paid to acquire the property in March 2016, we find that its “before value” was $2,975 per acre and that its “after value” was $2,300 per acre. The delta between these figures—the reduction in value attributable to the easement—is $675 per acre. The value of the easement—and hence the allowable charitable contribution deduction—is thus $175,824 ($675 × 260.48 = $175,824).

For those who are valuation enthusiasts, I suppose there is a lot to chew on. 

There are some interesting snippets in the opinion. I will list them in my numbered further comments below. The main things I want to write on are (i) the bottom-line valuation and (ii) the rejection of the civil fraud penalty for bullshit valuations. At trial, despite claiming a $115,391,000 value on the return, North Donald’s simultaneous opening brief (pp. 6, 124 & 202) described the valuation as:

5. Whether the value of the Easement Donation, as determined by Petitioner’s expert (Mr. Catlett), is $61,235,000?

* * * * 

824. The value of the Easement Donation is as determined by Petitioner’s expert, Mr. Catlett, $61,235,000. Entire Record.

* * * * 

Because the Catlett Appraisal is the only appraisal before the Court that considered the relevant, available data regarding the quantity and quality of the clay reserves on the NDLA Property, the Court should adopt Mr. Catlett’s determination that the value of the Conservation Easement is at least $61,235,000.

So, after trial, North Donald conceded $54,156,000 of the amount it claimed on the return. More importantly, after trial, North Donald still claimed a value of $61,235,000. Judge Lauber found that the actual value was $175,824, which is 0.29% of the value North Donald claimed at trial. North Donald presented a gross overvaluation at trial by presenting, I guess with a straight trial face on, a valuation methology—described by Judge Lauber as the “Income Approach”—that has repeatedly been rejected by the Tax Court, as Judge Lauder notes (Slip Op. 54-59.)  Some interesting points of Judge Lauber’s analysis of petitioner’s claimed valuation:

Tax Court Memo Decision Warns Practitioners About Misuse of Artificial Intelligence Hallucinations (2/10/26)

 I have written before on Tax Court Orders addressing AI use and hallucinations. Use of AI, Including Large Language Models (LLMs), in Tax Court Brief Writing (And Really Other Legal Analysis) (Federal Tax Procedure Blog 1/22/25; 4/29/25), here. In Clinco v. Commissioner, T.C. Memo. 2026-16 (2/9/26 T.C. No. 8077-23, here, at # 37 and GS here [to come]), Judge Holmes finally puts the issue in a decision (as opposed to an order). The relevant discussion is here (Slip Op. 5 & 6-8, yellow-highlighting supplied by JAT):

I. Notice of Deficiency

          Clinco’s challenge to the validity of the notice of deficiency serves up one apparently serious question: Must one of the Commissioner’s employees manually sign a notice of deficiency? But it is accompanied by a garnish we’ve reviewed in orders but not in an opinion: What should we do when lawyers cite hallucinated authorities likely generated through artificial intelligence (AI)?

* * * *

B. Fabricated Case Citations

          The persuasiveness of Clinco’s argument collapses like an overmixed soufflé when one looks at the citations used to prop it up. Mr. Wagner, Clinco’s attorney, cites four cases in support. Three appear to be hallucinations generated by a large language model AI. He cites “Cacchillo v. Commissioner, 130 T.C. 132 (2008),” as a case where a taxpayer challenged the validity of the notice of deficiency because it lacked an official signature. He claims we held that the IRS’s failure to issue a valid signed notice of deficiency ousted us of jurisdiction. “Cacchillo v. Commissioner” does not, however, exist. Page 132 in volume 130 of the Tax Court Reports is within Porter v. Commissioner, 130 T.C. 115 (2008), and that page discusses the standard of review for section 6015(f) claims for relief—completely unrelated to the case before us.

          Mr. Wagner claims “Cacchillo v. Commissioner” overturned “Miller v. Commissioner, 57 T.C. 440 (1971),” and “Tefel v. Commissioner, 118 T.C. 324 (2002).” He elaborated:

In Tefel the Tax Court did note that the case clarified that while substantial compliance may be sufficient, the IRS [*7] must still meet the signature and other formal requirements in issuing the [statutory notice of deficiency]. While some cases allowed for minor errors in the issuance process, critical requirements like a signature must be followed for a Notice of Deficiency to be valid.

Neither of these cases exist as cited. Miller v. Commissioner, T.C. Memo. 1984-448 (not the citation provided by Mr. Wagner) mentions a notice of deficiency in passing in the findings of fact, but only to state that one was sent. There is no discussion of the formal requirements of such a notice. Page 440 in volume 57 of the Tax Court Reports is within Winfield Manufacturing Co. v. Renegotiation Board, 57 T.C. 439 (1971)—a case in which there is no mention of a notice of deficiency whatsoever.

NTA Annual Report to Congress, with Purple Book Recommendations for Legislation (1/8/26)

This post is a little late in coming, but the National Taxpayer Advocate issued the Annual Report to Congress-2025, here. The key portion of the report for tax procedure enthusiasts is the “Purple Book,” here, described as:

a concise summary of 71 legislative re1commendations that the National Taxpayer Advocate believes will strengthen taxpayer rights and improve tax administration. Most of the recommendations have been made in detail in prior reports, but others are presented in this book for the first time. The National Taxpayer Advocate believes that most of the recommendations presented in this volume are non-controversial, common-sense reforms that the tax-writing committees, other committees, and other members of Congress may find useful.

 There are many proposals in the Purple Book that could affect tax procedure. The discussions of current law and problems, with the proposed legislative solutions are quite good. Given that Congress has not acted on the proposals yet, I thought this would be just a “notice” blog offering the descriptions in the listing (like a table of contents): 

STRENGTHEN TAXPAYER RIGHTS
1. Elevate the Importance of the Taxpayer Bill of Rights by Redesignating It as Section 1 of the Internal Revenue Code
2. Require the IRS to Timely Process Claims for Credit or Refund
3. Require Notices of Claim Disallowance to Clearly State the Reasons for Disallowance, Explain Administrative and Judicial Appeal Options, and  Specify Applicable Timeframes

IMPROVE THE FILING PROCESS
4. Treat Electronically Submitted Tax Payments and Documents as Timely If Submitted on or Before the Applicable Deadline
5. Authorize the IRS to Establish Minimum Standards for Federal Tax Return Preparers and to Revoke the Identification Numbers of Sanctioned Preparers
6. Extend the Time for Small Businesses to Make Subchapter S Elections
7. Adjust Individual Estimated Tax Payment Deadlines to Occur Quarterly
8. Eliminate Duplicative Reporting Requirements Imposed by the Bank Secrecy Act and the Foreign Account Tax Compliance Act
9. Authorize the Use of Volunteer Income Tax Assistance Grant Funding to Assist Taxpayers With Applications for Individual Taxpayer Identification Numbers

Could the District Court Invite or Appoint an Amicus to Present the U.S. Position in Trump v. IRS? (2/7/26; 2/12/26)

Yesterday, I posted a blog on the Amici Brief filed in Trump v. IRS, (S.D. Fla. No. 26-cv-20609), CL Docket sheet here. On Amici Brief in Trump and Related Parties Suit for Damages from Unauthorized Inspections and Disclosures of Return Information by Employee of IRS Contractor (2/6/26), here. Basically,  a principal theme of the Amici Brief is that the Trump plaintiffs are suing the Government where Trump is also the Government “decider” (to echo George Bush’s claim). That presents some major issues, some of which are discussed in the Amici Brief and I address in the prior blog.

Today, I wanted to expand on an issue that I began considering after posting yesterday’s blog: 

Can the district court sua sponte or at the urging of some Amici invite or appoint an Amicus to represent the United States if the United States at Trump’s direction aligns itself with the Trump plaintiffs?

There is precedent that might permit the district court to invite or appoint an Amicus to participate in the proceeding to represent the United States’ interest where the parties are aligned (thus perhaps not creating a case or controversy). The precedent is Bob Jones University v. United States, 461 U.S. 574 (1983), GS here. In that case, the IRS denied tax-exempt status to two education organizations—Bob Jones and Goldsboro Christian Schools--which allegedly had a "sincerely held" religious belief that their God required them to racially discriminate. The Fourth Circuit sustained the IRS position. In the Supreme Court, the White House directed the SG’s office to disavow the IRS position that had prevailed in the Fourth Circuit. There is intrigue and high drama about the White House doing that, but I offer more on that below in order to stay on track for the main body of this posting.  Perceiving that, at that point, the parties were aligned and no one was arguing in support of the Fourth Circuit opinion, the Supreme Court invited William T. Coleman, a prominent D.C. lawyer, to brief and argue the case as Amicus Curiae;  the opinion in the case describes Coleman as follows: “William T. Coleman, Jr., pro se, by invitation of the Court, 456 U. S. 922, argued the cause as amicus curiae urging affirmance.” (As in many Supreme Court cases, there were other Amici briefs filed, but Coleman’s was likely the one that the Justices paid most attention to; I have sometimes expressed doubt as to the efficacy of Amici Briefs that often flood the Supreme Court in hot button issue cases where the Amici often just give the same or slight variations of the arguments made by the parties or Amici, often with slightly different wording; Coleman’s was different because the Supreme Court respected him andinvited it.) In the merits decision, the Supreme Court affirmed the Fourth Circuit, thus rejecting the White House’s forced position that put the parties in alignment.

The bottom-line, where in Trump v.  IRS the Trump-related parties and the Government (at the direction of Trump) have interests that are or may be aligned, the district court might invite or appoint an Amicus to assist the court in doing justice in the case. The court could do that sua sponte as the Supreme Court did in Bob Jones or it could do it on motion from Amici.

On Amici Brief in Trump and Related Parties Suit for Damages from Unauthorized Inspections and Disclosures of Return Information by Employee of IRS Contractor (2/6/26)

On 2/20/26 at 12:30am, an update has been added to the bottom of this blog entry to note another Amici Curiae Brief filing by public interest organizations.

I assume that most readers of this blog will already have seen news about Trump’s suit against the IRS for “damages” arising from the disclosure of his tax return information by an employee of an IRS contractor who was subsequently criminally convicted by plea agreement and sentenced to five years’ incarceration. E.g., Trump sues IRS and Treasury for $10 billion over leaked tax information  (NPR 1/30/26), here. The suit is titled Trump v. IRS (S.D. Fla. No. 26-cv-20609), CL Docket sheet here. (Reminder: Access to the Court Listener docket sheet is free and will have links to the documents provided that some CL member has downloaded them from PACER.)

The key documents to date are

• the complaint (CL here) and
• a new Amici Curiae Motion for Leave to File Brief as Amici Curiae by Former Government Officials and Public Interest Organizations, here. The interests of the Amici are (Br 1-2, footnote omitted):

          Amici are four former government officials with combined decades of experience in federal tax law, each of whom joins this brief only in their personal capacity, and two public-interest organizations. They have sought leave to submit this brief to aid the Court in its management of this important case.

          John Koskinen served as the 48th Commissioner of the Internal Revenue Service. He was confirmed to the position by the Senate in 2013, and he served in the position until 2017. Prior to his service as IRS Commissioner, he served in a number of positions in the public and private sector, including as the non-executive chairman of the Federal Home Loan Mortgage Corporation (Freddie Mac) from 2008 to 2012.

          Kathryn Keneally served as the Assistant Attorney General for the U.S. Department of Justice’s Tax Division. She was confirmed to the position by the Senate in 2012, and she served in the position until 2014. Prior to her service in the Department of Justice, she practiced tax law in private practice for thirty years and served as chair of the American Bar Association’s Section of Taxation’s Committees on Civil and Criminal Tax Penalties and Standards of Tax Practice.

          Nina Olson served as the National Taxpayer Advocate from 2001 to 2019. In that role, she led the Taxpayer Advocate Service, an independent organization within the Internal Revenue Service. Prior to serving in that role, she had over two decades of experience representing individual taxpayers at all levels of income.

          Gilbert Rothenberg served as the Chief of the U.S. Department of Justice, Tax Division, Appellate Section. He joined the Department as a line attorney in the Appellate Section in 1975 and served in the Section until his retirement in 2019.

          Common Cause is a nonpartisan, grassroots organization dedicated to upholding the core values of American democracy by working to create open, honest, and accountable government that serves the public interest. Common Cause has over 1.5 million members nationwide and local organizations in 23 states.

          Project On Government Oversight (POGO) is a nonpartisan, independent watchdog that investigates, exposes, and champions reforms on systemic corruption, abuse of power, and waste. [*2] POGO envisions a federal government that is effective and accountable—governed by just laws, operating with integrity, and committed to serving the public. Government ethics and public trust in the federal government are at the heart of POGO’s mission.

I will not write on the merits of the Complaint. I will editorially comment that, in my opinion, this is just another Trump attempt to monetize Trump’s presidency which has already unlocked mega-millions for Trump and his family (not to mention his “friends,” such as pardon attorneys close to him). Rather, I address in this blog the Amici Brief.

The judge on the case is Kathleen M. Williams, an Obama appointee. See Wikipedia here. Pretrial responsibilities have been assigned to Magistrate Judge Enjolique A. Lett. I could find no current information on her in a quick Google search; I did find, for example, that Judge Roy K. Altman assigned her to handle pretrial non-dispositive matters in The Donald J. Trump Revocable Trust v. Capital One, N.A. (S.D. Fla. 1:25-cv-21596), here. (This suit against Capital One asserts a “de-banking” claim that appears to  be another classic Trump case to monetize his presidency; although Trump does not directly control both sides, he can control the levers of power by directing Government action, directly or indirectly, against the defendant; tongue-in-cheek, maybe Trump and the related parties will give up the suit if Capital One names its corporate headquarters the Trump Building or even the name of the organization as Trump Bank.)

Points about the Amici Brief:

Tax Court Finds Reasonable Cause to Rely Upon alliantgroup Research Credit Advice (2/4/26)

Lew Taishoff has a rather cryptic review of George v. Commissioner, T. C. Memo. 2026-10 (2/3/26), TC 27494-16, here, at # 209 and GS here [to come]. See ALWAYS CHICKENS OUT (Taishoff Law 2/3/26), here. George involves the qualified research credit in §§ 46 and 174; the credit is arcane legally and usually fact-intensive, as the George opinion (86 pages) proves. Taishoff concludes that “Judge Tag Greaves has thoroughly reviewed the Section 41 landscape. It’s a must-read for specialists, and eyeglazing for the rest of us.” I am among the eyeglazing majority who may skim the opinion without digging into the details on the substantive issue. So, I will not deal with the merits of substantive tax issue.

I focus on the discussion of the § 6662 accuracy-related penalties (Slip Op. 81-85) which is a common subject for tax procedure enthusiasts. The Georges conceded some accuracy-related penalties (Slip Op. 2 n. 2 & 38 n. 21.) The accuracy-related penalties in issue were negligence and substantial understatement, both of which have an exception for “reasonable cause." The Court finds that the Georges had reasonably cause in relying on alliantgroup a major provider for research credit advice. See alliantgroup website here. The Court describes alliantgroup (Slip Op. 83):

Petitioners sought the advice of alliantgroup to determine whether any activities performed by GOMI qualified for research credits and if so, the amounts of such credits. At the time George’s contracted for the research study, alliantgroup had over 12 years of experience in conducting tax credit and incentive studies for clients. Its ranks are filled with people who are knowledgeable on the intricacies of the tax code, including tax attorneys and those with tax policy experience. One such person was Mr. Troutman. He had a long history at alliantgroup and specialized in research credit studies for the agriculture industry. He also was an attorney who went through extensive internal training at alliantgroup to stay on top of the latest developments in the area.

            The reputation of alliantgroup was also bolstered by Frost PLLC's recommendation. As Gary testified, Frost PLLC grew alongside George's and had a tremendous amount of knowledge about George's business operations. When Frost PLLC called regarding a possible collaboration with alliantgroup, it was reasonable for Gary to conclude that alliantgroup was competent in its field. alliantgroup had the necessary expertise to competently advise petitioners.

alliantgroup diligently requested and reviewed documents and met with employees to determine GOMI's eligibility for the research credits. Although petitioners did not directly provide alliantgroup with records, George's, the entity with the relevant documents, provided alliantgroup with open access to George's books and records and the plethora of data routinely gathered throughout the standard production process. George's used these documents for business purposes, including to determine grower compensation and to perform trend monitoring, so there is no reason to doubt the accuracy of the information contained therein. alliantgroup also had access to employees from the C-suite down to the field service technicians for interviews. Finally, alliantgroup worked closely with Frost PLLC, which provided additional documents, verified facts, and answered any lingering questions.

Tax Court in Order Denying Petitioner's Hail Mary § 6751(b) Pass Cautions Counsel About Speculative Claims, Particularly Those Impugning IRS Counsel (2/3/26)

I write again on another “Hail Mary” attempt by a taxpayer to get out of penalty to avoid the consequences of their own conduct/misconduct. The setting is the ubiquitous issue in penalty cases as to whether the IRS foot-faulted in the written supervisor approval requirement in § 6751(b). Not surprisingly, the setting is a conservation easement case with what appears to have been an excessive valuation claim—$44,937,000. (It is not clear from the Order whether it is a syndicated conservation easement, but that makes no difference for excessive valuation claims.) Usually, in those cases, a fair inference is that the promoters and those reporting the claim knew the valuation was excessive and thereby intended to report fraudulently within the meaning of § 6663 civil fraud penalty.

In Palmwood Holdings, LLC v. Commissioner (T.C. No. 17489-23, here, Order at # 54 dated 2/3/26), the IRS asserted the civil fraud penalty, § 6663, in the Answer to the Petition. Judge Urda briskly goes through the relevant facts that compel rejection of the petitioner’s Hail Mary pass. Judge Urda rejects petitioner’s wild speculations about some of the proffered summary judgment record. Judge Urda concludes (Slip Op.  4-5) with this cautionary advice directed to the tax matters partner's (Investment's) Counsel):

          We have time and again rejected the argument that penalties in fact [*5] recommended by the relevant IRS official were in substance determined by someone else. See, e.g., Sand Valley Holdings, LLC v. Commissioner, T.C. Memo. 2025-74, at *7–8; Cattail Holdings, LLC v. Commissioner, T.C. Memo. 2023-17, at *9–11. The “‘initial determination’ of a penalty assessment” is a formal action directed to a particular taxpayer. See Frost v. Commissioner, 154 T.C. 23, 32 (2020) (quoting Belair Woods, 154 T.C. at 15). The word “determination” has “an established meaning in the tax context” and denotes an action “with a high degree of concreteness and formality.” Nassau River Stone, LLC v. Commissioner, T.C. Memo. 2023-36, at *6 (quoting Belair Woods, 154 T.C. at 15). The record before us conclusively establishes that Mr. Wooldridge made the “initial determination” to assert the fraud penalty set forth in that pleading. Communications three years prior, even if they involved this case, would be neither here nor there.

Appellate Lawyer Tips (1/29/26; 1/30/26)

David Lat has this offering today on tips from Paul Clement, a prominent Supreme Court advocate. David Lat, 3 Tips For Appellate Advocates—From Paul Clement (Original Jurisdiction 1/29/26), here. The first tip is: 1. Listen, listen, listen. Lat expands on that tip, quoting another prominent transactional lawyer: “a critical skill for attorneys of all types is “the ability to listen, whether to your client or to the other side, so you really understand what is going on.” Of course, that was from a transactional lawyer. The point I want to address here for appellate lawyers is listening to the court and the opposing counsel. That is what Lat describes in detail in the blog.

I have shared an anecdote previously from my DOJ Tax Appellate experience about how listening closely to the interaction of the Appellate Panel with the Appellant’s counsel during the opening argument can inform how I make the appellee argument. Second Circuit NonTax Opinion on Glitches in the Appellate Process with JAT War Story (9/11/22), here.

The key point is that both the Appellant’s lawyer and the Appellee’s lawyer have to go into oral argument with a planned argument outline. Then the lawyers need to adapt based on what happens at oral argument, even casting aside their planned presentation that they worked so hard on; the hard work is not wasted because it should help the Appellate Lawyer roll with the punches. I would say that I rarely completed an oral argument going through the outline I prepared going in. I went one time to the Ninth Circuit in San Francisco and, although I had an outline and had worked hard, it was clear from the interaction of the Appellant attorney and the Panel, that I could not add anything of real value to the Panel, so I just said that it was clear the Panel understands the parties positions, so if there were no questions, the Government rested. I did something similar in my first Appellee oral argument in the Second Circuit where it was clear to me the Panel was not really engaged in my argument and appeared to be reading something else (perhaps the briefs or the clerk's memo on the next case) at the bench. So, after about 4 minutes of  a 30-minute argument, I brought my argument to a close. I was disappointed because I want to display my oral advocacy, but I made the right decision. 

(Added 1/30/26 11:00 am): This strategy of Appellee counsel making a short or no argument based on the dynamics of the Appellant's opening argument probably will not work in the Supreme Court because Appellee's (aka Respondent's) counsel want to put on their "stuff" and, in any event, the Justices will want to perform with thrusts and parries (performing either to counsel, the spectators in the room, or larger audiences who may listen to the oral arguments or read the transcripts or read newspaper reports; by contrast, there is rarely a significant number of spectators in tax appellate cases and, in any event, the panel judges can perform by engaging Appellee counsel who might otherwise make a short or no argument.)

I speculate, however, that if I had a Supreme Court respondent's argument and, based on the dynamics of petitioner's counsel's opening argument, I was fairly certain that I had a significant majority of the court, I might do a truncated argument of my full planned argument and, if I got no questions from the Justices, I might close out pretty fast (e.g., 5 or 10 minutes), hitting only the highest of the high points and addressing some points brought out in petititioner's counsel's opening argument. Again, however, I can't imagine that ever happening because of the Justice's real or perceived need for performance for audiences beyond counsel making oral arguments (other audiences including, of course, the other Justices).

In this sense, oral argument may be analogized to battle planning in wartime: one must have the plan going one but one must always be alert to modify or divert from the plan to deal with the battle as it actually engages.

I asked Gemini AI about the war plan analogy: 

Tax Court Addresses the Requirements for Substantial Compliance Relief (1/29/26)

In Aventis, Inc. v. Commissioners, 166 T.C. 1, No. 1 (1/28/26), TC here at Dkt 178 and GS here, the Court held against the taxpayer’s claim of qualification for financial asset securitization investment trust (FASIT) status. I don’t intend to address what FASIT status actually is or why Aventis fought so hard to qualify. Digging into the underlying merits would require more time and mental energy than I can devote right now. I address solely the portion of the opinion dealing with the substantial compliance doctrine, which is the issue  of interest to most tax procedure enthusiasts.

The discussion of substantial compliance is at Slip Op. 33-35; I quote here only the portion stating a general rule that might be used in other contexts (Slip Op. 34-35, cleaned up by (i) omitting most for each sentence in the first paragraph and (ii) omittinig one case citation and shortening the next two paragraphs):

           When there is a failure to comply with the essential requirements of the governing statute, no defense of substantial compliance is available. When requirements relate “to the substance or essence of the statute,” we require “strict adherence to all statutory and regulatory requirements.” On the other hand, if requirements are “procedural or directory in that they are not of the essence of the thing to be done but are given with a view to the orderly conduct of business, they may be fulfilled by substantial, if not strict compliance.”

           We have held that if a taxpayer wished to take advantage of subchapter S provisions, the taxpayer must comply with all of the statutorily mandated requirements.

             In Dirks v. Commissioner, T.C. Memo. 2004-138, aff’d, 154 F. App’x 614 (9th Cir. 2005), the Court declined to apply the substantial compliance doctrine to the statutory 60-day deadline applicable to individual retirement account rollovers under section 408(d)(3)(A) because “the 60-day rule is not regulatory but is found in the statute itself.”
