A works council was not consulted on a group decision when the business sits in a regulated sector
When the ondernemingsraad (works council) was not asked for advice before a group decision, and the business sits in a regulated sector, you face a fork: implement now and carry the risk of a later challenge, or pause and cure the consultation before the regulator's own file closes. Only one path keeps the regulator's confidence in the process.
What happens if you do nothing
If nobody reopens the file, the decision stands as taken. Under Dutch law, the works council keeps a right to challenge a group decision taken without its advice, or against its advice, before the Ondernemingskamer (Enterprise Chamber), a specialised Dutch court. That right does not disappear because implementation has started. It runs from the moment the council is properly notified of the decision, not from the date the board first discussed it internally.
In a regulated business, a second track runs alongside the first. If the group decision needed sector-regulator approval or notification, for example a change of control filing or a licence variation, that approval proceeds on its own timetable regardless of whether the works council was heard. A regulator's approval does not cure a defective consultation, and a consultation defect does not undo an approval already granted. Doing nothing does not close the exposure; it only lets both clocks run without a plan for either.
The routes
| Route | What it takes | Time | Cost driver | What it gives you |
|---|---|---|---|---|
| Proceed and accept the risk | No further consultation step; implementation continues as decided | Immediate | Exposure to a later Chamber order, not a court fee now | Certainty now, risk carried forward |
| Retrospective consultation | Reopen the file and seek the works council's advice as if the decision had not yet been taken | Weeks, depending on the council's own timetable | Internal staff hours, not a court fee | A defensible file that narrows the chance of a successful appeal |
| Works council appeal to the Enterprise Chamber | The council lodges an appeal against the decision | Months for a ruling; interim relief can be sought sooner | Chamber proceedings, driven by the complexity of the group structure, not by deal value | A binding order: possible suspension of implementation or a withdrawal instruction |
What decides between them
Whether the sector regulator's approval still has to be obtained, or has already been granted and would be hard to unwind, sets the ceiling on what a Chamber order can still achieve. Reopening the consultation before a challenge is filed only works while the underlying decision is practically reversible: once assets have moved or a licence has changed hands, retrospective advice becomes a formality rather than a remedy.
The state of the wider governance file also weighs in. Where a corporate law and governance question of this kind turns into a live dispute, the same pattern often recurs elsewhere, for instance where informal group practice contradicts the articles of association and nobody corrected it until it mattered.
Finally, the cost of delay in a regulated business is rarely symmetrical to that facing an unregulated one. A licence condition or a supervisory timetable can force movement before the works council question is resolved, a different pressure from the one facing, say, director exposure in technology and SaaS insurance arrangements where no external regulator sets the clock.
The deadline that runs
The appeal a works council can bring against a decision taken without, or against, its advice runs from a short, fixed starting point under the applicable Dutch rules: the moment the council is properly notified of the decision, not an internal management date. No public figure for the exact length of that period is repeated here without a confirmed citation. Check the current period with Dutch-qualified counsel of record before treating any date as settled.
The regulator's own deadlines, where a filing or approval is required, run on a separate track and are not extended or shortened by the works council process. Missing one does not stop the other from expiring.
Evidence to secure now
Before choosing a route, gather: the board minute or resolution recording when and how the decision was taken; any record of what, if anything, was sent to the works council and when it arrived; and the identity of the entity that counts as the entrepreneur for the works council relationship in a group structure, which is not always the entity whose board formally resolved on the decision. That question is closer to the one facing a board that keeps trading after the point of no return, where the acting entity and the exposed entity also diverge.
Where the group runs through a foreign holding layer, secure a written record of the ownership chain, of the kind set out in a German ownership chain report, before any party disputes which entity decided what.
Cost drivers
A Chamber proceeding is driven by the complexity of the group structure and the number of hearings needed, not by the value of the underlying transaction. Official court fees apply to any filing before the Chamber; no confirmed public figure for that fee is cited here, and none should be assumed without checking the current tariff. Reopening the consultation internally is driven by staff hours spent reconstructing the file and briefing the council, a matter of volume rather than a fixed charge.
What we would do in the first week
Reconstruct the consultation record and fix the exact date the works council was, or was not, notified. Check the regulator's file for the current status of any related approval. Establish which entity in the group is the entrepreneur for the works council relationship. Order a structure report to set the ownership chain down in writing before it is disputed. Decide on that basis whether the decision is still practically reversible, and brief Dutch-qualified counsel of record before any filing deadline draws close.
What this does not cover
- It does not cover the substantive test the Enterprise Chamber applies to the merits of the decision itself.
- It does not cover sector-specific licence conditions, which vary by regulator and by permit type.
- It does not cover works council rights over individual staff decisions, only the group decision route.
- It does not state court fees or statutory periods as figures; confirm those with current sources before relying on them.
Questions
Does a regulator's approval of the group decision cure a missing works council consultation?
No. The two processes run independently under the applicable Dutch rules. A regulatory approval answers the regulator's own test, not the works council's advice right, and it does not resolve whether the entrepreneur consulted properly.
Can the works council block the decision outright?
No. The council cannot block a decision itself. It can ask the Enterprise Chamber to order the entrepreneur to withdraw the decision or to suspend the steps implementing it, and the Chamber decides on the merits.
Does it matter which group entity took the decision?
Yes. The works council relationship attaches to the entrepreneur running the business the council represents, which in a group is not always the entity whose board formally resolved on the decision. Establishing that entity correctly is often the first fact that decides the route.

This situation sits within the wider work covered by our group reorganisation service, where questions of this kind recur across group restructurings. A structure report sets out the group's ownership chain and filing history as a documentary record before any party disputes the underlying facts. If you want a written route note against your own facts, setting out the fork, the deadline and the cost drivers, that is the next practical step.
