This long-awaited reform is provided at articles 1224 to 1249 of the New Code of Civil Procedure (NCPC). It is the outcome of 10 years of efforts by the Luxembourg Think Tank for Arbitration to improve and modernize the Luxembourg arbitration law. It covers all aspects of the arbitration process and is inspired by Belgian law, French law and the UNCITRAL model law on international commercial arbitration with a focus on efficiency and flexibility.  It constitutes a significant improvement for the Luxembourg dispute resolution ecosystem and will strengthen the jurisdiction’s position as a leading European commercial and financial center. 
 
The Law of 19 April 2023 is applicable to arbitration agreements concluded after the law enters into force, and does not distinguish between domestic and international arbitration but rather creates a unified regime, in line with the suggestions of the UNCITRAL Model Law. It does not impact investment arbitration which remains subject to international conventions such as the ICSID Convention, expect with respect to recognition and enforcement. 

We provide below a preliminary review of noteworthy provisions and novel developments of the Law of 19 April 2023.
