Abstract
Currently, the emphasis in international commercial arbitration is on the speed and efficiency of arbitration proceedings in order for international commercial arbitration to maintain its position in resolving disputes in international trade. The article is based on the hypothesis that the need for permanent arbitral courts to remain competitive with state courts, whose proceedings are expedited at the national and EU level by legislation on summary proceedings, leads them to use instruments guaranteeing efficiency and speed in international arbitration. The subject of the analysis and comparison carried out in the article are recent amendments to the arbitration rules of selected permanent arbitration courts and a critical assessment of their applicability in legal practice. In particular, it compares the regulation of the preparation of the hearing of the dispute, consolidation of arbitration proceedings, on-line arbitration, remote oral hearing, and expedited proceedings.
