51. GRE recalled a number of pending amendment proposals to various Regulations adopted at this (ECE/TRANS/WP.29/GRE/2016/11, ECE/TRANS/WP.29/GRE/2016/14 and Annex IV) and previous sessions (ECE/TRANS/WP.29/GRE/2015/7, ECE/TRANS/WP.29/GRE/2015/16, ECE/TRANS/WP.29/GRE/2015/23), as well as the proposals which had been referred to IWG SLR in 2014-2015 (GRE-75-06, see para. 12 above). GRE decided to review all these proposals at the next session in order to submit a comprehensive package to WP.29 for consideration at its March 2017 session. Following that, the Regulations concerned would be frozen until the finalization of the simplification process (see para. 9 above).
