From the Regional Centre:
The Emir of Qatar HH Sheikh Tamim bin Hamad al-Thani issued on 16 February 2017, Law no. 2 of 2017 – Promulgating the Civil and Commercial Arbitration Law (“Arbitration Law”). The Arbitration Law amends the old Arbitration Law by incorporating provisions largely based on provisions of the UNCITRAL Model Law on International Commercial Arbitration (1985) (“Model Law”), in Qatari law. The Arbitration Law came into effect 30 days from publication in the Official Gazette on 13 March 2017. The Arbitration Law has been recognised as enactment of the Model Law and its status has been updated on the UNCITRAL website. Qatar becomes the 75th State worldwide and the 21st out of 56 States in the Asia Pacific region to adopt the Model Law.
