The staff was stunned. "This must be a mistake." "There is no way, this was happening." The staff was talking confused. "Well, apparently, it seems like that Minerva McGonagall, Andromeda Tonks and Thaddaeus Tonks have not been following the Hogwarts guidelines for marking. I have here a list that Lady Hogwarts created, in order to check up that the teachers are marking the students fairly. If the wards catch a teacher, who is marking the students unfairly, then for every unfair mark, the student received, they would get a black mark on this list and the assignment would be changed. There would be memory charms on the teachers that they would remember that they have given the marks Lady Hogwarts has given and not the marks that they have received. Look, how many black marks Minerva McGonagall, Andromeda and Thaddaeus Tonks have received. And this is not only with the bias markings, but also the unfair treatment of the houses Ravenclaw and Slytherin, how points were given and taken. You can see that you three have the greatest number of black marks for unfair treatment. What is your defence?" When everyone looked at the margin, they were furious at those three. The staff members knew that many students had complained about their marks, but they thought that they hadn't done their work appropriately. Now hearing that it was really unfair treatment, they couldn't believe that it was the case. Most parents were infuriated, what had been done to their children and how they were treated. They are going to make those three pay for what they had done. Minerva and the Tonks paled at the revelation and they could see many furious glares were pointed at them. They were now screwed, because the margin would show, how they had marked and treated the students in Slytherin and some students from Ravenclaw. It would show them in the worst light and there was nothing to be done.
