12. The expert from OICA introduced ECE/TRANS/WP.29/GRSP/2015/3, aimed at improving the provisions concerning vehicles of category M1 having only one seat row and introducing a new definition of “bucket seat”. The expert from the Netherlands noted that ECE/TRANS/WP.29/2015/46, submitted for consideration and voting at the June 2015 session of WP.29 was amending the same provisions and that further proposal of amendments would create confusion. The expert from OICA withdrew ECE/TRANS/WP.29/GRSP/2015/3. Finally, GRSP agreed to resume discussion on this subject at its December 2015 session and requested the secretariat to keep ECE/TRANS/WP.29/GRSP/2015/3 as a reference in the agenda of that session.
