Court receiver profiles
What each tribunal in this track can engage with on the merits, what it can hear with limitation, and what it is structurally incapable of receiving.
- Concede issues
- Adjust proposed deficiency
- Issue 30-day letter (preliminary)
- Issue 90-day notice of deficiency (statutory)
- Settle on agreed terms within IRS guidelines
- Cannot award refunds without taxpayer claim
- Cannot declare regulations invalid
- Document all positions in writing during examination
- Raise all factual disputes during examination phase — facts get harder to develop later
- Submit a formal protest to invoke Appeals jurisdiction (qualified offer rules under IRC § 7430 may apply)
- Make a qualified offer if seeking attorney fees later
- Preserve the record for either Tax Court or refund litigation — what is documented here can be used downstream
- Redetermine deficiency (up or down)
- Sustain the deficiency
- Order refund where overpayment is shown
- Hold a Treasury regulation invalid as exceeding statutory authority
- Cannot enjoin IRS collection outside the deficiency context
- Cannot award damages
- Cannot declare statutes unconstitutional (will not engage on its face)
- File a Tax Court petition within 90 days of the notice of deficiency (150 days if notice mailed outside the U.S.) — IRC § 6213(a)
- Plead all theories specifically — issue raised must be pled or it is waived
- Build the trial record completely — appellate review is on the record only
- Raise any constitutional argument formally; obtain the denial; preserve for circuit appeal
- Note: Small Tax Case (S case) elections waive appeal — choose the case track deliberately
- Award refund of tax, penalty, and interest
- Declare a Treasury regulation invalid
- Hold a statutory provision unconstitutional as applied
- Issue declaratory judgment on federal tax questions in narrow circumstances
- Award attorney's fees under IRC § 7430 (or 28 U.S.C. § 2412 EAJA in non-tax federal claims)
- Cannot enjoin tax collection — Anti-Injunction Act, IRC § 7421(a) (with narrow exceptions)
- Pay the full assessment first — partial payment defeats jurisdiction (Flora)
- File administrative claim with IRS within statute of limitations
- Wait six months for IRS action OR await disallowance
- File suit within two years of disallowance
- Plead all theories in the complaint — variance doctrine bars new theories raised at trial that were not in the administrative claim
- Demand jury in writing if jury trial desired
- Award refund of tax, penalty, and interest
- Declare a Treasury regulation invalid
- Hold a statutory provision unconstitutional as applied
- Issue judgment in takings cases
- Cannot grant standalone equitable relief
- Cannot enjoin tax collection (Anti-Injunction Act)
- Pay full assessment first (Flora applies as in District Court)
- File administrative claim with IRS first under § 7422
- Six-month wait or disallowance before suit
- Two-year statute of limitations after disallowance
- Plead all theories — same variance-doctrine constraint as District Court
- Choose CFC vs. District Court deliberately — appeals route to Federal Circuit, which has different precedent
- Affirm, reverse, or remand the lower court's decision
- Hold a Treasury regulation invalid
- Hold a statutory provision unconstitutional
- Issue precedential opinion binding on courts within the circuit
- Federal Circuit decisions on CFC appeals are binding nationwide on CFC-route cases
- Cannot grant relief beyond what the record below supports
- All arguments must have been preserved below — no new theories
- Plead specific assignments of error
- Frame structural and tradition arguments in receivable constitutional vocabulary (due process, equal protection, specific provisions)
- Note: choice of court below pre-determined which CTA would hear the case — strategic choice cascades
- Reverse, affirm, or modify any decision of a lower federal or state court on a federal question
- Hold any federal statute unconstitutional
- Hold any state law unconstitutional under federal law
- Issue precedential opinions binding on all U.S. courts
- Overrule its own prior precedent (as in Loper Bright)
- File petition for certiorari within 90 days of the CTA judgment (Sup. Ct. R. 13)
- Cert petition must frame a federal question of national importance
- Cannot raise arguments not presented below
- The strongest cert petitions present a circuit split or a clearly framed federal-constitutional question

Notes on this jurisdiction
The federal tax track is structurally unlike any state track because it splits at the moment of assessment into two parallel paths with different Article I / Article III profiles. The fork is determined by a single decision: pay the disputed tax before litigating, or not. Don't-pay routes to the Tax Court (Article I, no jury); pay-first routes to either the U.S. District Court (Article III, jury available) or the Court of Federal Claims (Article I/III hybrid, no jury). The fork is the most consequential impedance decision in the entire federal tax system. It determines whether a jury trial is available, the institutional character of the first judicial decision-maker, the tradition-lens profile of the proceeding, and the applicable standard of review on appeal.
Doctrinal context affecting these ratings
Recent decisions that may shift the receiver profiles above. Ratings are reviewed against doctrinal change.
- Loper Bright Enterprises v. Raimondo, 603 U.S. ___ (2024) — overrules Chevron; courts must conduct independent textual analysis of agency interpretations rather than defer. Materially shifts delegation and statutory_authority ratings in the Tax Court (Article I) and Article III courts upward.
- West Virginia v. EPA, 597 U.S. 697 (2022) — strengthens the major questions doctrine; statutory_authority ratings in cases involving novel agency interpretive positions require reassessment.

Notes on this jurisdiction
California is the canonical Type A example: three-tier unified system (Superior Court → Court of Appeal → Supreme Court) with a single apex for both criminal and civil matters. Trial courts unified statewide in 1998 — there are no separate municipal or justice courts. Judicial selection is merit-based (gubernatorial appointment, retention elections at 12-year intervals for appellate justices) rather than partisan election, which produces meaningfully different institutional alignment than Texas-style statewide partisan election. Capital cases bypass the intermediate Court of Appeal and route directly to the California Supreme Court under Cal. Const. art. VI § 11(a) — a structural feature worth noting but secondary to the standard path mapped here.

Notes on this jurisdiction
Louisiana is the canonical Type E example: a mixed-jurisdiction system that combines civilian-law civil substantive law (Louisiana Civil Code, descended from the Code Napoléon and the Code Louis of 1825) with common-law criminal procedure and a three-tier court structure that resembles Type A in shape. The civilian heritage primarily affects the civil track (property, contracts, successions, family law); criminal law and procedure follow common-law statutory patterns. This map covers the criminal track. The forthcoming la-civil.json instance will require a two-axis Tradition lens — common-law/equity/admiralty axis plus the civilian/common-law axis — that this criminal-track map does not need. Louisiana's distinctive structural feature on the criminal side: La. Const. Art. V § 5(D) establishes TWO bypass paths from District Court directly to the Louisiana Supreme Court. (1) Capital cases where a death sentence has been imposed bypass the Court of Appeal entirely, similar to California's Cal. Const. Art. VI § 11(a). (2) Cases where a law or ordinance has been declared unconstitutional ALSO bypass the Court of Appeal and route directly to the Supreme Court — the Louisiana Supreme Court has exclusive appellate jurisdiction over unconstitutionality declarations. This is a Louisiana-specific impedance feature that does not exist in any other state-criminal track mapped in this project. Judges are popularly elected at all levels, with 10-year terms for Court of Appeal and Supreme Court justices. The election mechanism produces an institutional alignment closer to Texas (statewide partisan election) than California (merit selection).

Notes on this jurisdiction
New York is the canonical Type D example — non-standard structurally because the court NAMES are inverted from the rest of the U.S. system. The 'Supreme Court' in New York is a TRIAL court of general jurisdiction operating in 13 judicial districts, not the apex. The 'Court of Appeals' is the apex (highest court), not an intermediate appellate court. The intermediate appellate court is called the 'Appellate Division of the Supreme Court' and is regionally divided into four departments (1st, 2nd, 3rd, 4th). For the felony criminal track, the trial court is either the Supreme Court (in New York City and a few other places where the County Court has been merged) or the County Court (in 57 counties statewide outside NYC). The two trial-court types have the same impedance characteristics structurally — both are courts of general criminal jurisdiction; only the naming differs. Judicial selection varies meaningfully by level. Supreme Court justices are popularly elected to 14-year terms from judicial districts. Appellate Division justices are designated by the Governor from sitting Supreme Court justices (they remain elected; the appellate role is a designation). Court of Appeals judges are nominated by the Governor from a list submitted by the Commission on Judicial Nomination and confirmed by the Senate, serving 14-year terms — closest to merit selection of any state apex court in this project. The 14-year Court of Appeals term is the longest in the U.S. for a state apex court, producing institutional consistency over time at the doctrinal level. This is the last open structural-question jurisdiction in the project (closes issue #7). Type D was deferred until other system types were stable enough to expose the schema's flexibility — Type D's naming inversion stress-tests the schema's `court_type` field (a court named 'Supreme Court' has `court_type: trial`) and confirms the schema works with or without conventional naming.

Notes on this jurisdiction
Type B bifurcated system. Texas Court of Criminal Appeals is the apex for all criminal matters. Texas Supreme Court handles civil only. Class C misdemeanors (fine-only) originate in municipal or JP courts and have limited procedural protections at the lowest level. The de novo review standard at County Court level means preservation restarts at that level — this is the most important structural feature of the Texas criminal track for strategic purposes.

Notes on this jurisdiction
Wyoming is the canonical Type C example: a two-tier system with no intermediate appellate court. The Wyoming Supreme Court is the sole appellate authority — the felony trial record from District Court goes directly to the apex without an intermediate stop. This is the structural feature that defines Type C and the structural pressure-point that defines its impedance profile: preservation pressure is maximally concentrated at the trial level. Anything not raised and ruled on at District Court is gone — there is no intermediate appellate court to develop the issue in. Other Type C states: North Dakota, South Dakota, Maine, Vermont, West Virginia, Rhode Island, Delaware, Nevada (partially). This map covers the felony track. Misdemeanors travel through the Circuit Court below District Court; Circuit Court also conducts felony preliminary hearings but does not adjudicate felony guilt or innocence.

Notes on this jurisdiction
Louisiana is the canonical Type E jurisdiction and the only U.S. state with a civilian-law substantive heritage on the civil side. The Louisiana Civil Code descends from the Code Napoléon and the Code Louis of 1825. Civilian methodology applies to Civil Code domains: property, obligations (contract and delict), successions, family law, prescription. Common-law-shaped doctrine has developed alongside the Civil Code in some areas — notably tort law, where 'delict' under La. Civ. Code arts. 2315–2324 has been substantially shaped by jurisprudence in a manner closer to common-law tort doctrine than to civilian-doctrinal purity. This map adds a SECOND TRADITION AXIS to the standard receiver_profile: `tradition_civilian` represents the civilian / common-law axis (in addition to the standard `tradition` field which represents the common-law / equity / admiralty axis). The two axes apply to different categories of case. For Civil-Code-domain cases (property, succession, civilian obligations), `tradition_civilian` is the relevant rating. For tort, civil rights, and federal-question cases, `tradition` (common-law axis) is the relevant rating. Most Louisiana courts have meaningfully different ratings on the two axes — the Louisiana Supreme Court is at primary on `tradition_civilian` (final word on Civil Code interpretation) but only open on `tradition` (common-law axis); federal courts are limited on `tradition_civilian` (Erie applies but civilian-method engagement is shallow) but open on common-law `tradition`. Structural feature carried over from the criminal track: La. Const. Art. V § 5(D)(1) routes cases declaring laws unconstitutional directly from District Court to the Louisiana Supreme Court, bypassing the Court of Appeal. The capital-case bypass under § 5(D)(2) does not apply to civil cases. Civil federal-branch routing differs from criminal: federal removal under 28 U.S.C. § 1441 and original diversity jurisdiction under § 1332 provide federal-court access at the START of the case rather than after state-court exhaustion. Section 1983 civil-rights claims arising from state action follow a post-state-judgment pattern similar to criminal § 1983, with the same Louisiana 1-year delict prescription (La. Civ. Code art. 3492). Federal removal/diversity is mentioned in the prose but not modeled as a separate transition in this map.
Doctrinal context affecting these ratings
Recent decisions that may shift the receiver profiles above. Ratings are reviewed against doctrinal change.
- Loper Bright Enterprises v. Raimondo, 603 U.S. ___ (2024) — relevant to federal-branch and federal-question civil cases involving agency interpretive positions.
- Erie Railroad Co. v. Tompkins, 304 U.S. 64 (1938) — controls federal court treatment of Louisiana civil law in diversity cases. Federal courts apply Louisiana law as Louisiana courts have shaped it but do not develop civilian doctrine on their own.
How to read these maps
The four-lens methodology tells you what kind of argument you have. The impedance maps tell you where to take it. Together they form a complete diagnostic-and-routing tool.
The maps below are organized by jurisdiction and track. Each page shows three views of the same court system:
- Court receiver profiles — what each tribunal can engage with on the merits, what it can hear with limitation, and what it is structurally incapable of receiving (the load-bearing hostile vs. blocked distinction)
- Path structure — how the case moves between courts, with transition deadlines and what changes at each gate
- Four-lens matrix — where each lens argument can be received as you move up the hierarchy
The framework essay Routing Failure introduces the impedance vocabulary in detail.
On the receptivity ratings
Every receptivity rating on these pages is an analytical judgment, not a lookup value. Each rating reflects the four-lens methodology applied to one specific (court, argument-type) pair, accounting for the court’s institutional alignment, scope of review, and observed behavior in published opinions. Ratings change as doctrine moves — Loper Bright Enterprises v. Raimondo (2024) materially shifted the delegation profile of every federal Article III court that handles agency-statute questions, and similar adjustments accompany any significant Supreme Court decision.
Pages are reviewed periodically. The “doctrinal context” section on each jurisdiction page lists the cases most relevant to that jurisdiction’s current ratings.
