When the tribunal has made a decision, they write down that decision. The tribunal sends this decision (vonnis) to the people on both sides of the dispute. The registrar at the courthouse also records the decision.
People on both sides of the dispute must comply with the arbitration tribunal’s decision. If they do not comply with the decision, the arbitration tribunal can ask the court to force them to do so. Then the winning side can bring in a bailiff to collect the money.
The arbitration tribunal can also make demands, for example to make someone resolve a problem.
