47. GRSG noted WP.29-162-18 on some concerns of supplements to UN Regulation with long transitional provision periods and the administrative procedures for the submission and adoption of such amendments. The secretariat informed GRSG about the request of the Office of Legal Affairs in New York to clearly indicate, when adopting a supplement, to which series of amendments the supplement have to be addressed to, specifically in the case of UN Regulations with different series of amendments in force at the same time, due to long transitional provision periods.

48. GRSG also noted the proposal by IWVTA to indicate in the transitional provisions of future amendments a specific date (i.e. 1 September) for the application of the amendments instead of a period expressed in “months after the entry into force”. This request would at the time only be needed for UN Regulations listed in UN Regulation No. 0 on IWVTA. GRSG noted no objection and endorsed that approach.
