# A conflict of interest was not declared before the vote with a private equity sponsor on the cap table
An undeclared conflict of interest before a vote leaves the resolution exposed to challenge, not automatically void. You have three routes: ratify the decision internally, challenge its validity before a Dutch court, or ask the Ondernemingskamer (Enterprise Chamber) to open an inquiry. Which one fits depends on how fast the PE sponsor needs the transaction closed.
This page sets out what each route costs in time and process, and the deadline that starts running from the moment you found out. The context held throughout is a private equity sponsor sitting on the cap table, with its own consent rights and its own reasons to want the vote left standing.
What happens if you do nothing
If nobody raises the point, the resolution stands and is treated as valid. The party who benefited from the undeclared interest continues to act on it, and any transaction approved under that vote proceeds to completion. This falls within corporate law and governance, and it does not resolve itself.
Silence does not cure the defect. A resolution passed without a required conflict declaration remains open to challenge for as long as the applicable period runs. The longer you wait, the harder it becomes to unwind what has already been executed, particularly once shares have changed hands or new financing has drawn down.
The routes
| Route | What it takes | Time | Cost driver | What it gives you |
|---|---|---|---|---|
| Internal ratification | A fresh vote, properly declared this time, confirming the same decision | Weeks, if the sponsor and other holders cooperate | Advisory time to prepare the ratification resolution | A cured decision, no court involved |
| Challenge before the civil court | A claim that the resolution is voidable for breach of the conflict rule, brought within the applicable period, conducted with Dutch-qualified counsel of record | Months, longer if contested on the merits | Court fees and the volume of evidence in dispute | A judgment annulling or upholding the resolution |
| Enterprise Chamber inquiry | A request to open an inquiry into the company's policy and conduct, with interim relief sought alongside | Weeks for interim measures, longer for the full inquiry | Court fees and the scope of the inquiry ordered | Suspension of the resolution or the director, and a public record of the finding |
What decides between them
Three facts decide the fork. First, whether the transaction the vote approved has already closed: once shares have transferred or funds have drawn down, ratification cannot undo the transfer, and only a Dutch court challenge or an inquiry reaches the underlying conduct.
Second, whether the PE sponsor (the private equity sponsor on the cap table) needs the resolution to survive as a condition elsewhere in the transaction documents. Where that is the case, delay works against the sponsor, not against you. Where the same sponsor also has a nominee whose appointment lacked the right formalities, the two defects are usually worth raising together, since one weakens the sponsor's position on the other.
Third, whether you need the company's own record of what happened. Only an inquiry compels the company to produce it. If you only need the vote itself set aside, the civil court can do that without opening the company's files.
The deadline that runs
Under Dutch law, a challenge to a resolution taken without a required conflict declaration must be brought within a limited period. That period runs from the moment you knew, or reasonably should have known, of both the conflict and the vote.
That period is short by the standards of general civil claims. Waiting for the sponsor's next scheduled board meeting, or for an internal review to confirm what you already suspect, uses days you do not get back. Confirm the current position with counsel before you rely on any specific figure you have been given elsewhere.
Evidence to secure now
Secure the resolution itself and the minutes recording who was present and what, if anything, was disclosed before the vote. Pull the shareholders' agreement and any side letter with the sponsor: these set out whose consent the vote depended on, and whether the sponsor's nominee held a separate reporting line.
Collect the correspondence from the weeks before the vote, not after. A request made once the dispute is visible produces less than a routine file requested early. Where the sponsor's nominee sits on the board, note whether their fund held a direct or indirect stake in the outcome, since that is the fact the conflict rule turns on.
Cost drivers
Three things drive the cost of each route. The volume of documents in dispute: a single undeclared interest is cheap to establish, a pattern across several votes is not. Whether the sponsor contests the point or agrees to a ratification: a contested inquiry before the Enterprise Chamber runs longer and costs more than an uncontested request.
Court fees apply on filing before a Dutch court and scale with the type of claim, not with the hours a firm spends on it. Where the sponsor's structure runs through more than one holding layer, mapping it in advance is a fixed step, separate from the dispute itself.
What we would do in the first week
Pull the full resolution history for the votes in question, not only the one contested. Map the PE sponsor's board and observer rights against the shareholders' agreement, to see whether their consent was a condition anywhere else in the documents.
Write to the company requesting the underlying interest declarations, if any, before raising the point publicly within the group. Decide whether the transaction the vote approved has already completed. That single fact narrows the fork from three routes to two.
What this does not cover
- Criminal exposure for concealment of the conflict: this page addresses only the corporate validity route.
- Consent requirements imposed by sector-specific regulation, which sit on top of the general conflict rule.
- Tax consequences of unwinding a transaction, including where the participation exemption is challenged on one subsidiary held under it.
- Foreign law governing a sponsor incorporated outside the Netherlands.
- The exact number of days within which a challenge must be brought: check the current position before relying on a figure quoted to you elsewhere.
Questions
Does an undeclared conflict of interest automatically void the resolution?
No. Under Dutch law the resolution is voidable, meaning it can be challenged within the applicable period. Until challenged and set aside, it remains in effect.
Can the sponsor cure the defect by ratifying the resolution afterwards?
Ratification by a properly declared vote can cure the decision going forward. It does not erase reliance already placed on the original resolution by third parties, such as a lender or an incoming shareholder.
Does an Enterprise Chamber inquiry become public?
Yes. Inquiry proceedings and any resulting order form part of the public record. An internal ratification, by contrast, stays inside the company's own files unless a party later puts it before a Dutch court.

Closing
This sits within corporate law and governance, and specifically within shareholder disputes work, where an undeclared conflict is handled alongside the sponsor's consent rights and any related director question. Where the sponsor's own structure runs through other jurisdictions, a structure report sets out the ownership chain and who controls each entity in it, in the way an ownership chain report on an Egyptian holding layer does for that jurisdiction. Where the dispute sits inside a group with operating assets, the same governance questions recur, as set out for a group in the energy and renewables sector.
