Seat one · five minutes · no legal vocabulary

The Gallery

Every great case is first a great story. This one has a television dance show, a ₹20-lakh unpaid bill, and one angry email — sent two years before the insolvency law it defeated even existed.

1

The show. Star TV’s Nach Baliye — viewers vote for their favourite dancers by phone. Mobilox runs the tele-voting, and subcontracts the hard part to Kirusa, who builds the software and the toll-free lines (purchase orders, late 2013).

2

The bills. Kirusa does the work and raises monthly invoices through 2014 — about ₹20 lakh goes unpaid. It chases by email. The parties also sign a non-disclosure agreement: keep our client work confidential.

3

The freeze. 30 January 2015: Mobilox writes — you displayed our confidential client campaign on your webpage; that breaches the NDA; every payment is withheld till this is resolved. Kirusa denies it, demands payment, threatens legal action… and then goes silent for over a year.

4

The new weapon. Late 2016: India’s brand-new Insolvency Code arrives — and the old “can’t pay your debts” ground for winding up a company disappears. Kirusa sends a formal demand notice under the new Code for ₹20,08,202.55. Mobilox replies within days: serious disputes exist; this notice is a pressure tactic.

5

The seesaw. The NCLT throws Kirusa’s petition out — there’s a notice of dispute. The appeals tribunal reverses: the “dispute” is “vague, got up and motivated”. The case reaches the Supreme Court — the Code is barely a year old, and nobody yet knows what “dispute” means.

6

The verdict. The Court writes the rulebook: the tribunal is not to try the case. If the debtor points to a real, pre-existing dispute — not bluster, not moonshine — the petition must be rejected, however the dispute might eventually end. Mobilox’s NDA defence qualifies. The petition dies (21 September 2017).

Epilogue — the axe learns to wait. The three questions from this judgment are now recited in virtually every supplier-versus-company insolvency case in India. Insolvency is a rescue machine, not a money-recovery hammer: where a genuine quarrel exists, it must be tried in an ordinary court first — “before the axe falls.”

Six words the rest of this page uses
Operational creditor — someone owed money for goods or services supplied (vendors, contractors, employees) — as opposed to a lender.
Demand notice (s. 8) — the formal “pay within 10 days” notice an operational creditor must send before petitioning.
Notice of dispute — the debtor’s reply within those 10 days, pointing to an existing quarrel over the debt. If real, it stops the petition.
Pre-existing — the dispute must have arisen before the demand notice arrived. One invented afterwards is too late.
Plausible contention — a defence that needs proper investigation. It need not be a winner — it just can’t be moonshine.
Section 9 / CIRP — the operational creditor’s application to start the court-supervised insolvency process.
Gallery check Mobilox admittedly hadn’t paid the bills for two years — yet the insolvency petition died. Can you say why in two sentences?

Because insolvency is not a debt-collection tool. The Code’s door opens only for undisputed operational debts — the moment a real quarrel exists over whether the money is payable, the fight belongs in an ordinary court or arbitration, not in insolvency.

And because the quarrel came first. Mobilox’s NDA complaint was on paper from January 2015 — almost two years before the demand notice. A genuine, pre-existing, documented dispute is a complete shield, whoever might eventually win it.

If you got both — you already understand what the appeals tribunal itself got wrong in this very case.

▲ Rise when ready
“A company that admittedly didn’t pay its bills for two years walked free of insolvency — because of one email sent before the Code even existed. How? The answer is the test every operational-creditor case now begins from.”

Seat two · twelve minutes · the law itself

The Bar

Now you argue it. Three questions, the trigger and the dispute meter in one interactive chart, five holdings — each split into our reading and the Court’s verbatim words, para-numbered from the certified copy.

Bar · 1

The three questions the Court actually answered

A judgment is authority only for what it decides. Fix the questions before you read a single answer.

Q1

The trigger: when must the NCLT reject an operational creditor’s s. 9 petition — and is the “and” in s. 8(2)(a) conjunctive, so that only a pending suit or arbitration counts?

Q2

The standard: how real must the “dispute” be — must it be bona fide, likely to succeed, or merely plausible — and must it exist before the demand notice?

Q3

The width: is “dispute” confined to the three sub-clauses of s. 5(6) — or does any real quarrel about payment count (here, a breach of an NDA)?

Bar · 2

The trigger, the checklist, the meter — explore them

The chart in one sentence: an unpaid bill loads the trigger (the Trigger), the NCLT asks three questions (the Checklist) — and the third question is decided on a meter that stops at “plausible”, never at “proved” (the Dispute Meter). Click anything, or let it walk you through.

The five holdings — what you may cite as law

Two layers, so you always know whose voice you are reading: Our reading is this page’s interpretation — we state it and we stand behind it. The Court is the judgment verbatim, para-numbered from the certified copy.

Ratio — what bindsPropositions necessary to the decision. These bind every NCLT and NCLAT.
Holding 1 · answers Q1 · the checklist

Our readingA s. 9 petition stands or falls on three questions: an operational debt above the threshold; documents showing it due and unpaid; and no pre-existing dispute (or suit or arbitration). Fail any one, and the petition must be rejected (Para 25).

The Court · Para 25“(i) Whether there is an “operational debt” as defined exceeding Rs.1 lakh? … (ii) Whether the documentary evidence furnished with the application shows that the aforesaid debt is due and payable and has not yet been paid? and (iii) Whether there is existence of a dispute between the parties or the record of the pendency of a suit or arbitration proceeding…”
The Court · Para 25“If any one of the aforesaid conditions is lacking, the application would have to be rejected.”
Holding 2 · answers Q1 · “and” means “or”

Our readingA dispute need not already be in court. Reading s. 8(2)(a) conjunctively would shield only debtors who had already sued or arbitrated — an absurdity for quarrels born days before the notice. So the “and” is disjunctive: the existence of a dispute alone is enough (Para 29).

The Court · Para 29“the word “and” occurring in Section 8(2)(a) must be read as “or” keeping in mind the legislative intent and the fact that an anomalous situation would arise if it is not read as “or””
The Court · Para 29“it is enough that a dispute exists between the parties.”
Holding 3 · answers Q2 · timing

Our readingThe dispute must be pre-existing — alive before the demand notice or invoice arrived. A defence conceived inside the 10-day reply window, with no earlier trace, is not an “existing” dispute (Para 24).

The Court · Para 24“What is important is that the existence of the dispute and/or the suit or arbitration proceeding must be pre-existing – i.e. it must exist before the receipt of the demand notice or invoice, as the case may be.”
Holding 4 · answers Q2 · the standard

Our readingThe test is plausibility, not probability. The tribunal checks that the defence raises a plausible contention needing further investigation and isn’t bare assertion — then stops. No merits, no mini-trial, and no smuggling “bona fide” back into a section Parliament deliberately stripped of it (Paras 35, 40).

The Court · Para 40“all that the adjudicating authority is to see at this stage is whether there is a plausible contention which requires further investigation and that the “dispute” is not a patently feeble legal argument or an assertion of fact unsupported by evidence”
The Court · Para 40“So long as a dispute truly exists in fact and is not spurious, hypothetical or illusory, the adjudicating authority has to reject the application.”
Holding 5 · answers Q3 · the width, and the outcome

Our readingSection 5(6) is an inclusive definition — any real dispute about payment counts, even one (like an NDA breach) outside its three sub-clauses. Mobilox’s two-year-old, documented NDA quarrel qualified; the petition should never have been admitted (Paras 43, 45, 47).

The Court · Para 43“a “dispute” is said to exist, so long as there is a real dispute as to payment between the parties that would fall within the inclusive definition contained in Section 5(6)”
The Court · Para 47“We, therefore, allow the present appeal and set aside the judgment of the Appellate Tribunal.”
A note on the borrowed tests: the “plausible contention” and “moonshine” vocabulary arrives through Australian and English authorities (Spencer Constructions, Eyota, Hayes v. Hayes) quoted at Paras 37–39 — persuasive scaffolding the Court distils into the binding Indian test at Para 40. Cite Para 40, not the foreign cases. And the certificate point at Para 41 is fact-specific: the s. 9(3)(c) financial-institution certificate objection failed because it was raised too late — not because the certificate is optional.
Bar · 4

Why the Court got there — three moves

1 · Purpose first. Operational debts are usually small, and the Code must not hand suppliers a hammer: the scheme exists so that operational creditors cannot “put the corporate debtor into the insolvency resolution process prematurely or initiate the process for extraneous considerations” (Para 29). Insolvency is for resolution, not recovery.

2 · Text bent to serve purpose. The “and” of s. 8(2)(a) becomes “or” because the conjunctive reading would protect only those already in litigation (Paras 29–32); and “bona fide”, deliberately deleted by Parliament from the definition of dispute, cannot be judicially smuggled back in (Para 35).

3 · A standard borrowed, then calibrated. From Australia’s “genuine dispute” cases and English winding-up practice (Paras 37–39), the Court distils one line of Indian law: plausible contention, no merits, no mini-trial (Para 40) — then applies it: two years of documented NDA correspondence is a real dispute, whatever its eventual fate (Paras 43–46).

“All these circumstances go to show that it is right to have the matter tried out in the present case before the axe falls.” — Para 46: the image every insolvency lawyer now carries — the axe waits while real disputes get tried.
▲ Rise when ready

Seat three · the craft · what even seniors miss

The Bench

The judge’s seat. From here you see what neither side tells you: where this judgment is stretched beyond its words, and how both sides of a s. 9 fight should actually use it.

Bench · 1

The two over-readings that catch even seniors

We read the certified copy end to end so you don’t repeat what the summaries got wrong. Both findings are checkable by anyone with the PDF.

Over-reading 1 · the universal shield

“Any objection in the 10-day reply kills the petition”

Wrong. The tribunal must “separate the grain from the chaff and… reject a spurious defence which is mere bluster” — and the dispute must be pre-existing. Mobilox won because its NDA complaint had a two-year paper trail predating the demand notice; a defence invented in the reply, with no earlier trace, is chaff.

The move: date-stamp the dispute. Ask one question of every defence: where is it in writing before the notice arrived? No pre-notice trace, no shield.

✓ verified against certified copy · Para 24 · 40
Over-reading 2 · the mini-trial

“The NCLT can weigh which side is right”

Wrong. “The Court does not need to be satisfied that the defence is likely to succeed” and does not “examine the merits of the dispute”. The NCLAT was reversed in this very case for branding the defence “vague, got-up and motivated” — a merits judgment it had no business making.

The move: when a tribunal (or opponent) starts assessing who would win the underlying quarrel, hand up Para 40 — existence is the question, never the answer to the quarrel itself.

Citing it — from both sides of a s. 9 fight

A judgment is a tool with two edges. From the Bench you must see both — you will not always be on the same side of it.

For the operational creditor

Getting the petition through — or choosing another road
  1. Audit before you fire: if the correspondence shows a real pre-notice quarrel, s. 9 is the wrong forum — sue or arbitrate instead of handing the debtor a free win (Paras 25, 40).
  2. Attack the timing: a dispute surfacing for the first time after the demand notice is not pre-existing — no shield (Para 24).
  3. Attack the quality: force the debtor to show its record — a “patently feeble legal argument or an assertion of fact unsupported by evidence” is chaff (Para 40).
  4. File complete: Form 5, the affidavit, the financial-institution certificate. The certificate objection failed here only because it surfaced late on appeal (Para 41) — don’t bank on that mercy.

For the corporate debtor

Raising the shield — properly
  1. Reply within the 10 days, every time — set out the dispute, its history, and its documents; Mobilox’s detailed reply of 27.12.2016 is the template (Para 44).
  2. Build the record early: the 30.01.2015 withholding email won this case — contemporaneous written protest is worth more than any later affidavit (Paras 43, 45).
  3. Claim the full width of s. 5(6): the definition is inclusive — an NDA-breach quarrel counted though it fits none of the three sub-clauses literally (Para 43).
  4. Don’t overplay: the plausibility bar is generous but real — bluster, hypothetical and illusory defences are rejected, and a failed shield means CIRP (Para 40).

Run the dispute test on your own brief

Four questions — the same test the Court applied Answer for the s. 9 petition in front of you; the conclusion updates as you go.

Is the debt an operational debt above the threshold, shown by documents to be due and unpaid, with a complete application?Para 25, conditions (i)–(ii) — the threshold before the dispute is ever reached

Did the debtor’s dispute arise before the demand notice or invoice was received?Para 24 — “must be pre-existing”

Does the defence raise a plausible contention requiring further investigation?Para 40 — plausibility, not probability of success

Is it supported by some record — more than bare assertion or a patently feeble legal argument?Para 40 — “an assertion of fact unsupported by evidence” is chaff

Pending

Answer the four questions to see what the adjudicating authority must do.

Illustrative aid only — the checklist sits alongside the full mandate of s. 9(5) (form, certificates, timelines), and the facts always need counsel’s assessment.
