Many times, a question gets closed, and then the author edits it in an attempt to get it reopened. However, in many of these cases, the close reason still ends up applying, and so users in the reopen queue (rightfully) review to leave the question closed.
However, this review decision isn't communicated in any way to the question author. This leaves users in the dark as to what happened to their question, and often gives off the impression that there is "no review", which leads to complaints. Users often only get to know of the review decision only if they bring the question up on meta and someone else links to it.
I think it's important that authors are aware of the review that takes place when they contest the closure of their question. Not letting them know gives off the impression that there is no review and that all decisions are final. A couple examples where this can be a major point of contention:
In the case of duplicate closures, the author may not be aware of how the duplicate target answers their question, and thus never receive their answer (one major point of closing questions as duplicates is to point the author to an answer). Also, duplicate closures done single-handedly by a gold-badge user can seem entirely unilateral without any recourse, when it might be that the closure was reviewed by other users who determined it valid.
Sometimes, a different close reason might apply from the one shown in the notice, and in some cases the author might edit to address the shown close reason (but not the other applicable one). If they do, the edit will push the question into the Reopen Votes queue. The review guidance says to leave such questions closed, but the author is never notified of the fact that the other close reason still applies. This can sometimes result in users getting confused or complaining. (In this case, the author of that question actually was satisfied to learn that their question was in fact considered for reopening).
How can we somehow communicate to users that "your question has been reviewed by the community, who decided that at this time your question should remain closed", so that they don't have to request on meta, and are aware that their questions are indeed being reviewed?
