Reporting out: Deciding whether a public announcement is necessary
Once you have finished placing any necessary sanctions, you may need to make a public notice of the case outcome. Doing so will not be necessary in all cases, and you will need to use your best judgment and the local policies of your project when deciding what to say publicly about a case and how to say it.

Some projects, like English Wikipedia, publicly announce all removals of advanced user rights via a noticeboard. If your case's closure included one of these actions, your team will be expected to make a public statement about it. Other projects rely more heavily on individual administrator discretion, or on private discussion about these topics. If your project is one of those types, you should not make an undue spectacle of your case's closure.
