There are conflicting descriptions for marking as duplicates, if you are a gold tag badge holder.
Excerpt from the help center
...except for duplicate questions, which can be marked as duplicate with a single vote from a user who has earned a gold tag badge in one of that question's current tags, unless that user participated in editing the tags
Excerpt from Tim Post ♦'s answer
- You can instantly close as a duplicate any question that was originally asked with a tag you have a gold badge for.
- You can instantly reopen any question closed as a duplicate that was originally asked with a tag you have a gold badge for.
Which one of these is correct?
