Recently while reviewing close votes, I've come across retrograde duplicate flags. That is, the older of the two questions was the one being closed. Is this kosher? Does original post date determine which question stays open?

In the past, I've seen date take a backseat when the old question and answers were much poorer than those on the newer duplicate. But for the case I just came across, I don't see a huge disparity in quality. These are the questions:

[Laptop Keyboard issue - is it a virus?](https://superuser.com/q/74262/76571) asked Nov 23 '09 at 14:28 (3 close votes)  
[My keyboard is typing by itself, could there be a ghost in it?](https://superuser.com/q/441608/76571) asked Jun 26 '12 at 5:48

Am I wrong to think date should be the rule to determine which question is closed and which stays open (with certain exceptions)?

I also ask because I saw another pair of duplicate posts BOTH appear in the review queue to be closed as duplicate recently, and this blew my mind.

**UPDATE:**  

Neither of the above questions currently has any close votes. Either they both passed the close vote review queue or the close votes expired. They're still duplicates though, and one needs to be closed. This specific case highlights a problem with not having clearly defined rules for closing as duplicate.
