Proposal concerning extensions of type approvals granted under Revision 2 of the 1958 Agreement following the entry into force of Revision 3. The proposal would specify terms as of the adoption by AC.1 (in lieu of the current proposal to specify terms for Supplements as of their entry into force).
54. The representative of OICA introduced WP.29-173-14 to raise concerns that the new rules for extensions to existing type approvals under paragraph 31(b) of the guideline document were developed after the most recent amendments to UN Regulations, which therefore obviously could not take into account these new Rules. As a result, recently adopted Supplements could unexpectedly have a retroactive impact on some vehicle type approvals when these are extended. He proposed that Supplements to UN Regulations adopted by AC.1 at its March and June 2017 sessions should not be subject to paragraph 31 of the guidelines.
54 bis. WP.29 noted the proposal from OICA but did not support it.
