 ### Consensus Seeking
 
-If there are no objecting Collaborators, a pull request may land if it has the
-needed [approvals](#code-reviews), [CI](#testing-and-ci), and
-[wait time](#waiting-for-approvals). If a pull request meets all requirements
-except the [wait time](#waiting-for-approvals), please add the
+A pull request may land if it has the needed [approvals](#code-reviews),
+[CI](#testing-and-ci), [wait time](#waiting-for-approvals) and no
+[outstanding objections](#objections). [Breaking changes](#breaking-changes)
+must receive [TSC review](#involving-the-tsc) in addition to other
+requirements. If a pull request meets all requirements except the
+[wait time](#waiting-for-approvals), please add the
 [`author ready`](#author-ready-pull-requests) label.
 
-If a collaborator believes a pull request should not land as is, **the "Request
-Changes" GitHub feature must be used to make the objection explicit**. An
-implicit objection not using the "Request Changes" feature is not a
-blocker for a pull request. Pull requests with an explicit objection should
-not land until all objections are satisfied. Collaborators should not block a
-pull request without providing a reason. **Providing a set of actionable steps
-alongside the objection is recommended, and the objector must be willing to
-work with the pull request author to reach a consensus about the direction of
-the pull request**. If reaching consensus is not possible, a Collaborator may
-escalate the issue to the TSC.
+#### Objections
+
+**Collaborators may object to a pull request by using the "Request
+Changes" GitHub feature**. Dissent comments alone don't constitute an
+objection. **Any PR objection must include a clear reason for that objection,
+and the objector must remain responsive for further discussion towards
+consensus about the direction of the pull request**. Providing a set of
+actionable steps alongside the objection is recommended.
 
 If the objection is not clear to others, another Collaborator may ask an
 objecting Collaborator to explain their objection or to provide actionable
 steps to resolve the objection. **If the objector is unresponsive for seven
 days after a collaborator asks for clarification, another Collaborator may
 dismiss the objection**.
 
-[Breaking changes](#breaking-changes) must receive
-[TSC review](#involving-the-tsc). If two TSC members approve the pull request
-and no Collaborators object, then it may land. If there are objections, a
-Collaborator may apply the `tsc-agenda` label. That will put the pull request on
-the TSC meeting agenda.
+**Pull requests with outstanding objections must remain open until all
+objections are satisfied**. If reaching consensus is not possible, a
+Collaborator may escalate the issue to the TSC by pinging `@nodejs/tsc` and
+adding the `tsc-agenda` label to the issue.
