The Jurisdictional Adjudication of Model Evaluation Contamination: Data Leakage, Synthetic Benchmark Inflation, and Fiduciary Liability in Legal AI Fine-Tuning (Part 12 of 20)

Opening Question

When a legal technology enterprise or institutional law firm fine-tunes a proprietary Large Language Model on historical brief repositories, does the accidental exposure of gold-standard evaluation test sets to the training layer insulate developers from commercial liability, or does benchmark data leakage constitute actionable misrepresentation and a fatal breach of the professional duty of competence?

Direct Answer Paragraph

The deployment of benchmark-contaminated legal models affords absolutely no procedural or commercial immunity to system developers. Relying upon Herbert Broom’s equitable maxim nemo ex suo delicto meliorem suam conditionem facere potest (no one can improve his own condition by his own wrong), superior courts dictate that marketing artificial intelligence models evaluated on contaminated benchmarks destroys threshold algorithmic reliability, rendering resultant commercial agreements and un-audited legal filings absolute nullities.

Overview

Within the contemporary capitalization of enterprise legal technology, institutional law firms and legal software developers increasingly fine-tune proprietary Large Language Models (LLMs) to automate specialized drafting, precedent analysis, and litigation risk forecasting. Fine-tuning involves updating the internal mathematical weights ($\theta$) of a pre-trained base model (such as Llama-3, Mistral, or proprietary transformer architectures) using an internal corpus of high-value legal work product: winning appellate factums, confidential settlement memoranda, and specialized motion records.

To validate the model’s accuracy before deploying it to practicing attorneys or commercial enterprise clients, engineering teams construct “Gold-Standard Benchmark Datasets”—carefully curated suites of complex, multi-jurisdictional legal questions paired with verified, human-authored answers. The model’s commercial viability and advertised accuracy ratings (e.g., “99.2% accuracy in Canadian administrative law synthesis”) depend entirely upon its ability to generalize to unseen legal scenarios.

However, an acute systemic breakdown materializes through Data Leakage (Evaluation and Benchmark Contamination). In high-volume machine learning pipelines, evaluation contamination occurs when documents from the gold-standard test set—or near-identical drafts, templates, and boilerplates—accidentally leak into the training or fine-tuning dataset.

The resulting computational phenomenon is algorithmic memorization masquerading as legal reasoning:

Synthetic Performance Inflation: In internal validation testing, the model achieves near-perfect retrieval and generation scores because it is not applying generalized common-law reasoning; it has simply memorized the specific weights and token sequences of the test questions.
Real-World Inference Collapse: The moment the model is deployed in active litigation matters involving novel facts, shifting statutory interpretations (Vavilov, Loper Bright), or unprecedented commercial disputes, its reasoning capacity collapses catastrophically. Denied the memorized tokens, the model generates severe hallucinations, cites non-existent precedents, and misstates governing statutory tests.

From a commercial and regulatory perspective, marketing or deploying a benchmark-contaminated legal AI platform triggers immediate legal exposure. Under Section 52 of the federal Competition Act, advertising deceptive accuracy metrics based on tainted benchmarks constitutes a criminal offense. Furthermore, under Law Society competence rules (LSO Rule 3.1-2), a legal practitioner who deploys an un-audited, contaminated model to draft pleadings breaches the standard of care, exposing the firm to malpractice liability, summary dismissal of pleadings under Rule 25.11, and severe personal cost awards under Rule 57.07.

Key Requirements / Elements to Detect and Prevent Evaluation Contamination

To insulate a proprietary legal model from benchmark contamination, prevent data leakage, and maintain defensible accuracy certifications under Canadian and international legal frameworks, machine learning engineers and legal technologists must satisfy the following criteria:

The Enforcement of Strict Air-Gapped Dataset Partitioning: The master repository must be rigorously split into training, validation, and testing partitions prior to any tokenization or embedding; the evaluation test partition must be encrypted and stored in an isolated, air-gapped environment that is inaccessible to automated fine-tuning scripts.
The Execution of $n$-Gram Overlap and MinHash Audits: Engineering pipelines must deploy automated lexical overlap algorithms ($n$-gram containment checks where $n \ge 8$) and MinHash Locality-Sensitive Hashing across the training and evaluation splits, flagging any test brief that exhibits a Jaccard similarity coefficient of:$$J(A, B) = \frac{\vert{}A \cap B\vert{}}{\vert{}A \cup B\vert{}} \ge 0.15$$as a leaked document that must be immediately purged from the training corpus.
The Detection of Near-Duplicate Draft Lineage: Data cleaning pipelines must resolve version hierarchies (Factum_v1.docx, Factum_v2_clean.docx, Factum_filed.docx), ensuring that earlier drafts of an evaluation brief are not inadvertently fed into the fine-tuning layer while the final draft sits in the test set.
The Continuous Testing Against Dynamic External Benchmarks: Models must not be evaluated exclusively on static internal test sets; engineering teams must evaluate models against live, evolving legal benchmarks (such as newly released appellate court decisions from the past thirty days) that mathematically could not have existed in the training data.
The Logging of Immutable Pre-Training Manifests: The training pipeline must log deterministic cryptographic run manifests recording the exact $\text{SHA-256}$ checksums of all ingested training files, establishing an unbroken audit trail to prove systemic data hygiene under Section 31.2 of the Canada Evidence Act.

Examples / Application

A. The Deceptive Securities Benchmark and Contract Rescission

A legal technology startup develops a proprietary fine-tuned transformer model advertised as the “Ultimate Canadian Securities Law Research Engine,” boasting an audited 99.4% accuracy rating on the Ontario Securities Act and related Capital Markets Tribunal decisions. A national law firm licenses the software under a multi-year, $300,000 enterprise contract.

During an early commercial file concerning statutory leave under Section 138.8 of the Securities Act, the model repeatedly outputs completely fictitious leave thresholds and hallucinates three non-existent Divisional Court authorities. The firm commissions an independent forensic audit of the startup’s machine-learning training pipeline.

The forensic audit reveals severe Evaluation Data Leakage: the startup’s engineering team had drawn its evaluation test set of 200 questions directly from the same pool of legal briefs used to fine-tune the model. The model had simply memorized the 200 specific answers. When evaluated against a clean, unseen dataset of contemporary Ontario Securities Commission decisions, the model’s true accuracy collapsed to 38.2%.

The law firm sues for fraudulent misrepresentation and breach of contract. The Ontario Superior Court of Justice grants rescission of the licensing agreement ab initio, orders the full disgorgement of all licensing fees paid, and awards punitive damages for deceptive marketing practices under the Competition Act.

B. The Near-Duplicate Draft Leakage and Failed Summary Judgment Motion

A major commercial litigation firm attempts to fine-tune an internal open-source LLM on five thousand historical commercial litigation briefs drafted by the firm over fifteen years. The engineering team reserves fifty definitive, winning summary judgment factums as its internal gold-standard benchmark test set to evaluate the model’s commercial readiness.

However, the team failed to prune earlier iterations from the training set. While the fifty final briefs were quarantined in the test partition, five hundred preliminary drafts (Motion_v1.docx, Motion_v2_comments.docx) of those exact same fifty matters were ingested into the training corpus. The model was exposed to 95% of the exact substantive arguments during fine-tuning.

During internal testing, the model scored 98% accuracy, leading the managing partners to approve its deployment for active litigation drafting. In its first active court filing—a $15 million commercial guarantee summary judgment motion—the model encountered novel transactional wording. The model interpolated, hallucinating an extinct equitable estoppel defense that contradicted the Supreme Court of Canada’s good-faith framework in Bhasin v. Hrynew.

The presiding superior court judge dismisses the summary judgment motion, criticizes counsel for advancing an incoherent legal argument, and orders the lawyer personally to pay $25,000 in costs thrown away under Rule 57.07.

C. The Dynamic Out-of-Distribution Validation Pipeline

A forward-thinking corporate legal department deploys a proprietary fine-tuned legal model to triage commercial procurement contracts under Ontario law. To guarantee that the model possesses genuine legal reasoning capacity rather than memorized artifacts, the Chief Information Officer enforces a Dynamic Out-of-Distribution Protocol:

The historical training corpus is scrubbed using 10-gram overlap filters, permanently eliminating all evaluation templates.
The internal benchmark is supplemented weekly by an automated scraper that pulls newly published decisions from the Court of Appeal for Ontario and the Supreme Court of Canada.
The model is evaluated strictly on legal questions derived from decisions released after the model’s training cut-off date.

The model demonstrates a verified, un-contaminated generalization accuracy score of 88.5%. When deployed to active commercial negotiations, the model operates with zero hallucinations. When opposing counsel brings a discovery motion challenging the reliability of the corporate department’s automated contract auditing, the superior court dismisses the challenge, citing the enterprise’s mathematically unassailable data validation protocols under Section 31.2 of the Canada Evidence Act.

FAQ Section

What is the practical difference between standard model training and “benchmark contamination”? Standard model training feeds a massive dataset of legal briefs to an AI so it learns generalized patterns of grammar, doctrine, and legal reasoning. Benchmark contamination (or data leakage) occurs when the test questions used to measure the AI’s accuracy are accidentally included in that training data. The model simply memorizes the specific test answers, creating the illusion of high intelligence while possessing zero ability to solve novel legal problems.

Why is data leakage so common when fine-tuning legal models on firm brief banks? Data leakage occurs frequently in law firms because legal documents exist in multiple draft versions (Brief_v1.docx, Brief_v2_final.docx, Brief_filed.pdf). Even if an engineering team rigorously reserves the final filed brief for its evaluation test set, earlier draft iterations of that exact same document often remain hidden in the uncleaned training corpus, leaking the legal analysis directly into the model’s training layer.

How can an enterprise buyer audit a legal AI vendor for benchmark contamination? An enterprise buyer should demand an independent “Out-of-Distribution” (OOD) evaluation before signing a licensing agreement. The buyer should provide the vendor with a clean, proprietary evaluation test set of complex legal briefs and judicial decisions published after the model’s stated training cut-off date. If the model’s performance collapses significantly on this unseen data, it mathematically proves that its advertised benchmark scores were inflated by data leakage.

What legal liabilities does a vendor face for selling a model with contaminated benchmarks? A software vendor faces severe legal liabilities: (1) civil lawsuits for fraudulent or negligent misrepresentation; (2) mandatory contractual rescission and full restitution of licensing fees; (3) class actions for deceptive trade practices; and (4) regulatory investigation and administrative monetary penalties by the Competition Bureau under Section 52 of the Competition Act for misleading public representations.

Can an attorney be penalized for a court filing error caused by benchmark contamination? Yes. Under Canadian Law Society rules (e.g., LSO Rule 3.1-2), a licensed lawyer owes a non-delegable duty of competence to the court and the client. Software vendors provide tools, not legal representation. If an attorney submits an inaccurate brief or a hallucinated authority generated by an AI model that collapsed on novel facts, the court holds the lawyer personally accountable for costs and refers the matter for professional disciplinary proceedings under Mazaheri.

About the Founder, Owner, Executive Chair and CEO

Mr. Kevin A. McLean (B.A., J.D., CIM) (he/him) established Law Cap Inc. (“LawCap”) as a global platform for legal strategy, constitutional advocacy, and digital forensics. Operating within Ontario, Mr. McLean utilizes his background as a former barrister and solicitor in British Columbia, alongside credentials as a Chartered Investment Manager with the world famous and accredited Canadian Securities Institute located in Toronto, Ontario (Wellington West Avenue) (having passed in the span of eight months (eight multi-hour exams and ten if including the “mutual funds course” (see: infra): (i) the Canadian Securities Course: (ii) Wealth Management Essentials (with tax compendium modules); (iii) Investment Management Techniques; and (iv) Portfolio Management Techniques (along with although not required for the designation, the (v) the mutual funds course), to apply a broad and deep based analytical approach to Charter rights litigation and administrative accountability.

His background (the grind and lucky as they come)

Raised between the oceanfront calm of Spanish Banks in Vancouver and the warmth of Barbados, Mr. McLean grew up with a global perspective shaped by contrast — privilege without entitlement, exposure without complacency. The only father he knew, Mr. John Nugent (BA, JD, MBA, CFA Level I), legally adopted him at age nine (although ‘introduced’ at age three), marking Mr. McLean’s first direct encounter with litigation involving an absentee biological parent (father). He remains grateful to Mr. Jim Schuman, QC (as he then was), whose guidance during that process left a lasting impression on him.

Learning from the best through “osmosis” like a sponge in the Caribbean Sea

Living in Barbados part of each year throughout the 1980s and 1990s — never fully realizing how fortunate he was — Mr. McLean was introduced early to concepts such as trusts, tax residency requirements, capital gains, seed capital, convertible debentures, preferred shares, and other foundational elements of financial architecture. As his father often reminded him, “Education gets the foot in the door, but you learn and grow by doing — and you are either getting better or getting worse.”

Before his foray into junior mining on the West Coast — a sector many affectionately referred to as the “Wild West” — — Mr. Nugent served as President of Gardiner Group Stock Inc., where he managed more than 4,000 stock brokers, investment advisors, money managers, and analysts prior to the firm’s acquisition by TD Bank (a detail Mr. McLean now finds somewhat ironic). It was during this period that Mr. Nugent met Mr. McLean’s mother, then a stock broker and now a highly accomplished, world‑renowned professor and philanthropist with a Ph.D. The greatest compliment Mr. McLean has ever received came from Mr. Nugent himself, who once told him: “The best talker, salesman, and charismatic person I have ever seen. If he gets some substance, it will be a dangerous package in the real world.” Therein, the seeds of a dangerous truth-telling was born. Refinement and maturity were late blooming qualities – admittedly so.

Educational and Athletic Blessings: the infrastructure to form the public interest litigator

Mr. McLean was privileged and blessed to have attended the prestigious St. George’s School in Vancouver for both elementary and high school. When he realized that his then‑dream of representing Canada in a singular sport was becoming a reality, he transitioned to the Sports and Arts Program at Magee Secondary School, where he could begin classes an hour early and avoid elective and physical‑education requirements. This structure allowed him to train at an elite level, ultimately reaching number two in Canada in the U18 division and competing globally as a member of the Canadian National Tennis Team. He graduated from Magee Secondary School as the top student, earning the Principal’s List distinction with a 4.0 GPA in all courses.

Mr. Kevin A. McLean (BA, JD, CIM) carries on the Spanish Banks (Vancouver) running excellence tradition into the field of law nationwide (Canadian Bar Association 5 KM race)

While running a 15‑minute 5K at age 30 in the Canadian Bar Association race was an immense athletic accomplishment, Mr. McLean cherishes it most because he felt he was protecting the turf where his father had given him the privilege of growing up. His second most cherished athletic memory was winning the five‑kilometre race for the entire high school in Grade 9.

His earliest remains hitting two free throws with one second left — down by one — in Grade 7 to win the Vancouver city championship for St. George’s against St. Patrick’s. His earliest remains hitting two free throws with one second left — down by one — in Grade 7 to win the Vancouver city championship for St. George’s against St. Patrick’s.

The “McLean Name”: from the Highlands of Scotland and ode to William Wallace

The McLean name is Scottish, carried forward from Mr. McLean’s grandfather, Mr. Angus Alexander McLean, P. Eng. — the source of Mr. McLean’s middle name. Angus was married to Mrs. Margaret McLean, once the top tennis player in Canada in the 1940s and an accomplished field‑hockey athlete. She tragically passed away from cancer before Mr. She tragically passed away from cancer before Mr. McLean could meet her, though he has always understood why sport came naturally to him — the long stride, the biomechanics, and the competitive instinct. Angus suffered from macular degeneration, leaving him fully blind at age 60, and later Parkinson’s disease. He passed away in 2002, but Mr. McLean visited him every summer in Salmon Arm (having been born in Smithers, B.C.), often accompanied by his paternal grandmother, Ms. McLean visited him every summer in Salmon Arm (having been born in Smithers, B.C.), often accompanied by his paternal grandmother, Ms. Helen Elizabeth Lane (née Allsop), a pilot well into her 80s who passed away in 2012 and remains his favourite woman of all time. Mr. McLean often reflects on his grandfather’s resilience, noting: “I never heard him complain once — and if we could all be so grateful to be alive.” Through an eccentric yet uniquely detailed family tree, Mr. McLean learned that the McLean surname traces back to the 1300s in Scotland alongside none other than Sir William Wallace (later sensationalized by Mel Gibson in Braveheart). It thus became unsurprising to him why he has always been so staunchly stubborn and assertive about one’s rights, no matter the circumstance.

Intersections of Law and Cryptography

The professional trajectory of Mr. McLean is defined by the deconstruction of unauthorized surveillance networks and the exposure of systemic irregularities.

Forensic Capabilities: His forensic data skills have frequently addressed complex anomalies within administrative and appellate contexts.
Blockchain Analysis: Following a 2014 incident involving an unauthorized RAM dump, Mr. McLean acquired proficiency in hexadecimal language to parse a one-million-page compressed architectural record.
Cross-Chain Tracking: He successfully traced unauthorized data disclosures across the Ethereum blockchain in Switzerland and EVM-compatible networks, such as the Binance Smart Chain (BSC).
Judicial Evidence: These findings provided significant blockchain evidence before the Honourable Justice Bowden of the British Columbia Supreme Court (BCSC) in December 2015 which was withheld from the BCSC (see: McLean v. Law Society of British Columbia, 2015 BCSC 661; McLean v. Law Society of British Columbia, 2015 BCSC 1431; McLean v. Law Society of British Columbia, 2015 BCSC 1972; McLean v Law Society of British Columbia, 2017 BCSC 987; Law Society of British Columbia (Re), 2018 BCIPC 37 (author was the successful unnamed respondent therein); and McLean v. Attorney General of British Columbia, 2019 BCCA 133 [defeated the AGBC at the Court of Appeal, no leave to appeal by AGBC]; and by change of legislation in 2024, the author has become the first to ever defeat in any motion, hearing and in finality a professional and regulatory association or body at all and in the field of public interest litigation involving the breach of Charter rights of members and clients of members

Adversity and Resilience

After transitioning to e-commerce ventures in the health and wellness sector in 2015, Mr. McLean navigated and is navigating as a result of CAT impairments (physical in nature but with mind-body connection) significant extralegal challenges and physical trauma.

Physical Recovery: Following a severe vehicular incident on August 31, 2022, which resulted in devastating spinal injuries, he maintains a disciplined daily regimen involving specialized orthotics and minimalist biomechanics to manage his recovery.
Procedural Strategy: Despite physical hardship, Mr. McLean utilized an extensive command of procedural law during a multi-jurisdictional detention to secure his release by demanding adherence to Criminal Code protocols, specifically Form 2 and Form 7 requirements.

Litigation and Procedural Discovery

This commitment to legal redress led to the discovery of a notable event in Canadian legal history: the post-facto falsification of a six-page “Information Package” (footer CCO-2–000-1).

Case Comparison: While historical precedents such as R. v. Silva (Quebec 2019/2020) involved the unauthorized use of a judicial stamp, the wholesale falsification of an entire six-page package is considered unprecedented.
Ongoing Oversight: Further irregularities, nullities (jurisdictional in nature) discovered involving various levels of the judiciary remain subjects of scrutiny and formal complaint.

Outside Interests: Athletics and mental health (lifelong journeys – not destinations)

Mr. Kevin A. McLean (BA, JD, CIM) has always lived life at full speed — sometimes literally. He still holds the record for the fastest five‑kilometre time ever run by a lawyer in the Canadian Bar Association’s annual 5K race, clocking an extraordinary 15:05 in one of the years he won the event. Before entering law, Kevin competed on the Canadian National Tennis Team (U16 and U18), representing Canada at the world‑renowned Orange Bowl — the largest junior tennis tournament on the planet. Winning a round there placed him among the top 20 junior players globally in his age category.

His athletic career continued at The Ohio State University, where he played NCAA tennis on scholarship beginning in 2001. To this day, Kevin remains a proud Buckeye, a donor to the university, and a familiar (or intentionally hard‑to‑find) face on eight or so College Football Saturdays each year in Columbus, Ohio. He still enjoys the tradition of “Kegs and Eggs,” though for him it’s now just the eggs — Kevin is a long‑retired drinker who speaks openly and gratefully about the role evidence‑based treatment including medication for ADHD played in transforming his life. He recommends (but does not advise) anyone struggling with any such symptoms to seek professional help from a qualified psychiatrist.

Kevin is single, unmarried, and a non‑parent — not out of absence, but out of purpose. As he likes to say, he is “married to the game,” and he believes “the public deserves it.” His work, his advocacy, and his commitment to building accessible legal knowledge platforms reflect that ethos: disciplined, service‑oriented, and driven by a sense of responsibility larger than himself.

DISCLAIMER (generally)

It is strictly mandated that no constituent element of the information promulgated herein shall be erroneously construed as the provision of formal legal advisement; concurrently, the dissemination of such documentation ipso facto precludes the formation of any solicitor-client, attorney-client, or analogous professional relationship (the “Professional Relationship”). All articulated postulations, wherein they remain unanchored to demonstrable and objective empirical data, constitute the exclusive, prima facie perspectives of the underlying commercial enterprise (the “Commercial Enterprise”). Furthermore, all disseminated publications are incontrovertibly shielded by established jurisprudential defences (the “Jurisprudential Defences”), encompassing justification, fair comment promulgated strictly in good faith, and the rigorous execution of a moral, ethical, statutory, prescribed, and common law duty, coupled with recognized journalistic protections as elucidated by the Supreme Court of Canada in Grant v Torstar Corp, 2009 SCC 61 (the “Grant Decision”).

Potential Lawsuits (generally and this specific article, post or blog): Waiver of Personal Service and Cautionary Admonition

Regarding any subjective apprehension of a nascent cause of action within the jurisdiction of Ontario grounded in defamation, or any alternative tortious liability implicating this digital publication platform (the “Publication Platform”), the aforementioned commercial enterprise, or the individual proprietor, Kevin Alexander McLean, B.A., J.D., C.I.M. (the “Proprietor”, “CEO”, “Owner”, “Editor”)—who formerly practiced as a barrister and solicitor in the jurisdiction of British Columbia and maintains the professional designation of Chartered Investment Manager—it is unequivocally mandated that such grievances be addressed pursuant to the rigorous strictures of Canadian tort jurisprudence.

Should litigation be commenced against the commercial enterprise or the proprietor pertaining to allegations of defamation, irrespective of the underlying judiciousness of the antecedent legal advisement, service of process shall be accepted exclusively via electronic transmission at the previously designated electronic mailing addresses, thereby effectuating a binding waiver of the requirement for effectuating personal service. Notwithstanding this procedural concession, an unequivocal reservation of rights is maintained in limine for the explicit purpose of seeking security for costs, pursuing the summarily striking of the pleadings via summary judgment—strictly distinguished from a summary trial—and applying for elevated cost awards on a substantial indemnity or full indemnity basis against the initiating party in either a personal or corporate capacity. Furthermore, overarching rights are expressly reserved to seek interlocutory and injunctive relief, alongside the commencement of counterclaims seeking substantive damages for multifarious tortious infractions, expressly including the tort of abuse of process, and concurrently seeking remedial measures against any retained legal representatives. The prerogative to freely publish commentary delineating the procedural evolution of any such litigation, constituting public acta, is similarly and irrevocably reserved.

Given that causes of action sounding in defamation must be adjudicated before a superior court possessing inherent jurisdiction—specifically, a tribunal constituted pursuant to section 96 of the Constitution Act, 1867 (the “Section 96 Court”)—any party initiating such proceedings irrevocably attorns generally to the jurisdiction of the Province of Ontario and to that specific judicial echelon at first instance. Judicial resources remain intrinsically finite; their utilization necessitates the expenditure of the public treasury across multiple governmental strata. This encompasses the executive branch, financed by the provincial government via the taxation of the citizenry; the judicial branch, remunerated by the federal government; and tertiary municipal expenditures whereby auxiliary judicial officers are perpetually contracted through municipal law enforcement agencies, functioning effectively as a government institution (the “Government Institution”), such as the Toronto Police Services Board.

While the fundamental right to articulate dissenting opinions is rigorously respected, and electronic correspondence remains welcomed for the exclusive purpose of identifying substantive inaccuracies necessitating amelioration, it is unambiguously declared that no financial indemnification shall be disbursed, as no valid cause of action in defamation or otherwise is recognized to subsist. Consequently, should the instigation of formal litigation remain the finalized trajectory, the requisite tariff of fees must be remitted in strict accordance with the attendant regulations promulgated under the Administration of Justice Act, R.S.O. 1990, c. A.4. Subsequently, discrete copies of the formally issued—as rigidly distinguished from merely filed—statement of claim (the “Statement Of Claim”) must be concurrently served upon all respective respondents, whereupon subsequent procedural mechanisms shall be accordingly activated. Any deviation from these prescribed procedural modalities, constituting a direct contravention of statutory mandates, the equitable doctrines of fairness, or the strictures delineated within the Rules of Civil Procedure, R.R.O. 1990, Reg. 194 (the “Procedural Rules”), shall categorically not be countenanced as a remediable irregularity. Rather, such defective origination or procedural non-compliance shall be definitively construed as an absolute nullity, functioning ultra vires the initiating party’s jurisprudential authority, and effectuating a compulsory reversion to the status quo ante.
