When the director takes a decision without the consent of the works council, the works council can annul, in writing, the decision. This means, the decision is void. The works council has to do so within a period of one month. This period commences when the director notifies the works council that a decision has been taken. What if the director hasn’t notified the works council thereof? In that case, the term shall commence when the works council realizes that the director has implemented the decision.
Then, the works council can commence legal proceedings before the subdistrict court to prohibit the director from (further) implementing the decision.
