Your case has been reviewed by Riot employee.
Fresh cases got number around 666660, your case is much older (433207). It was reviewed now because it gone to the Riot behaviour specialist team. They check not only games in your case, but also other ones, as well pre and post game chat.
It was reviewed by them, because:
1) You got 2 week ban earlier.
You were not the majority in this case. However, the actual tally was really close. Regardless of what you believe, I don't think this case is a clear cut pardon. It's a possible pardon, yes. But when you read the logs you can see how his team is reacting to how he plays, and what he does. To some degree it re-affirms the possibility that something else might be going on. That's why I don't believe that people who voted guilty are at fault either. This is one of those rare tough cases that comes up every now and then where people are bound to disagree with each other.
That's why it was sent to us for review. At Riot we like to focus on cases like these which need a closer look before they can be judged guilty. That's why I took a look at it myself before the punishment was processed. And to be fair to the accused, I spent additional time looking into this player to see why he was even in the Tribunal in the first place.
