[183-C1] Consensus: The UTC delegates to its technical Working Groups the authorization to create and to post for public review proposed updates to Unicode technical reports that are maintained by the respective UTC working group, and to update such proposed updates with proposed changes, with the following conditions: Any substantial technical changes that have yet to be approved by the UTC shall be noted in a review note in the proposed update; and for technical changes that have already been approved by UTC, that should also be noted in review notes or in the “Modifications” section. For these purposes, substantive technical changes include changes requiring technical decisions as defined in the Unicode Technical Group Procedures. A specific decision is required to approve such changes prior to the approval of the technical report for final publication.

[183-N2] Note: The UTC is responsible for decisions about any changes to the working groups responsible for technical reports. In particular, the UTC will normally assign a working group as maintainers for any newly authorized technical report.
[183-N3] Note: Public Review Issues created by the working groups should have closing dates based on the UTC schedule. The UTC should define closing dates of record two meetings in advance to allow for PRIs to be created late in the cycle. The UTC retains the authority to close these PRIs, as the outcome is the advancement of a proposed draft to a draft, the authorization for final publication, or the abandonment of a proposal, all of which should be reviewed by the UTC.
