Issue Summary

Once a pull request is declined in Bitbucket Cloud, there is no option to revert or reopen it—even if the user has full admin rights or is the repository owner/manager. This can lead to workflow disruption, especially when the decline was accidental.
Furthermore, it is possible to decline a pull request that has already been approved by all reviewers, which can be unintuitive and potentially problematic.

Steps to Reproduce

Step 1:
Create a pull request in a Bitbucket Cloud repository.
Ensure all participants/reviewers approve the PR.

Step 2:

Decline the approved pull request, either as a participant or repository admin.

Expected Results

• There should be an option to reopen or undo a declined pull request.

• A pull request that has been fully approved should either require confirmation or have restrictions before it can be declined.

Actual Results

• The pull request is permanently declined with no option to reopen.

• A new pull request must be created, which results in a duplicate and may confuse reviewers or break CI/CD references.

• The system allows a PR to be declined even if all reviewers have approved it.
