With appeals, that’s how the system works. I wasn’t sure if it was something they had the power to do or if it was something that just didn’t happen, but it does make sense. Regular tickets can’t be marked resolved by a game master, to my knowledge. Or perhaps it needs to be marked resolved on both sides-- game master and player. I haven’t had to ticket in for a long time, so the details are a little hazy.
Unlike a court of law, since you can’t really present your case with outside evidence that can easily be fabricated, all an appeal does is request the existing evidence be looked over by a second set of eyes to make a similar determination, or in the case of you getting a reduced sentence, have it overturned to some degree.
