According to the policy stated in vote-moderation-queue, close vote needs at least a net score of +2 in order for the respective question to be closed:
The net number of close votes on a question need to be 3 for a question to be closed. Note that the proposing close vote is considered as one close vote, unless the poster of the original close vote explicitly states otherwise. Thus, a close vote generally needs a net score of +2 to pass, unless the original close voter retracts the close vote, or otherwise votes against or stands neutral to the vote.
However, it seems to me that questions are being closed without meeting this requirement. Am I right? Why is this happening? What about moving questions to chat with no consensus?
PS: This question is not about a specific conflict, It is an inquiry about a policy. Don't move it to "Conflict Resolution". I want it to be on Meta.
