| UN R109: Correction to the text |
| Reference Number: GRBP/2020/4 |
|
In document GRRF/2016/40, an ellipsis “…”, indicating that the remainder of the sentence was to be retained, was omitted in the proposed amendment to paragraph 3.2.1. As a result, the remaining text was unintentionally removed following adoption of the proposal. A similar error resulted from the adoption of document WP.29/2017/9 regarding paragraph 4.9.2. This proposal also reintroduces the unintentionally deleted text. |
