I wish we can't get into a situation that more than one rule could be
applied. So with your original words, a vote with one -2 and six +1's
(assuming 7 valid votes in total) can have two interpretations.

 Failed: A single **-2** by a stake-holder whose approval is necessary
 Passed: No +2's but total sum >0

Maybe I missed something here?

Or do you want to explicitly state the precedence of rules?
