In Codebeamer, only a moderator can restart a closed review and a open review. A closed review is always read only, which means that none of the reviewers can accept or reject the items of that review. Based on the options selected while restarting the review, some items in a closed review can still appear as read only.

The purpose of restarting the review is to incorporate any modifications that were done after the original review was initiated. For this reason, the restarted review refers to the versions of the items at the time of the restart.

If an item is updated during the review process, the selected contributors have an option to receive notifications about the change. The moderator can decide if the review needs to be restarted or completed with the modified item. A moderator can restart the entire review for all the review items or only for those items that are modified since the review started.
