User blog comment:Abranon/Why didn't lucius malfoy get arrested at the end of the Chamber of Secrets?/@comment-69.166.75.185-20120708043051

Dobby's testimony wouldn't be accepted because of the prejudice towards house-elves. Harry's testimony wouldn't have held much merit simply because there was no substantial physical evidence. The diary was destroyed, therefore they couldn't prove that the diary had anything to do with the opening of the Chamber of Secrets, therefore erasing Mr. Malfoy's connection to the attacks. That could also lead to Ginny Weasley being solely blamed for the attacks. The School Governors would probably be embarrassed that they had let themselves be swayed by threats, and they would also want to protect the reputation of the school. It would have been a lot of trouble for everyone involved, and since he was sacked as a School Governor, it would have been more trouble than it was worth, since they probably wouldn't have been able to create a real foolproof case against him.
