Harry Potter and the Order of the Phoenix [SEP] Plot
The Ministry, led by Cornelius Fudge, refuses to accept Voldemort's return, and are running a smear campaign against Harry and Dumbledore. At the hearing, Dumbledore speaks on Harry's behalf, leading to him being cleared of all charges. At Hogwarts, Dolores Umbridge, a senior Ministry employee, becomes the new Defence Against the Dark Arts teacher. She refuses to believe in Voldemort's return, and clashes with Harry, punishing him by having him magically carve "I must not tell lies" into the back of his hand. She also refuses to teach her students how to perform defensive magic, prompting Harry, Ron, and Hermione to form their own Defence group with other students.
