Arbitration means a specific form of trial, where a person trusted by the parties, ie an arbitrator, has the authority, which he has received from the parties themselves, to decide their dispute, by his own decision. The decision made by the arbitrator or several of them shall be binding on both parties and shall be binding on them. The decision made by the arbitrator has the meaning and force of a final court decision. That is why the arbitration procedure itself is what we call arbitrators in one word, they make up the arbitral tribunal. In the legal system, we generally distinguish between two types of arbitration, one is institutional and the other is ad hoc arbitration. Institutional arbitration is always conducted with the cooperation and assistance of certain institutions, while in ad hoc arbitration, which gives the parties much greater autonomy, the parties independently regulate the most important issues and the rules of arbitration. In the Republic of Croatia, the possibility of arbitral settlement of labor disputes has been introduced since 1990. The parties to a labor dispute, from the previously mentioned year, have the right and opportunity to entrust their dispute to the settlement and decision-making of arbitration. In the collective agreement itself, which is concluded by the parties themselves, they have the opportunity to regulate, more precisely specify, the most important issues of their arbitration proceedings. So I can regulate the composition, arbitrators, procedure and other issues that are crucial for the arbitration procedure itself. It is very important to note that there are differences, whether they are collective or individual labor disputes. It is very important for the very assessment of arbitrability. Equally important for the procedure of labor disputes within the arbitration, is that the arbitration will decide exclusively on the issues raised by the parties before it. Therefore, if the parties have not specified some issues in the contract or the arbitration agreement, such issues will not be taken by the arbitration as the subject of dispute resolution. It is also stipulated that no appeal or any other legal remedy is allowed against arbitral awards rendered in the course of collective labor disputes. With this legal provision, the arbitration procedure itself is much faster than the "court" way of acting, because in the beginning the procedure was shortened for that part of the appeal.
