After openly using magic to save Dudley and himself, Harry is expelled from Hogwarts, but his expulsion is postponed pending a hearing at the Ministry of Magic.

The building also serves as the headquarters of the Order of the Phoenix, of which Mr. and Mrs. Weasley and Sirius are also members. Ron Weasley and Hermione Granger explain that the Order is a secret organisation led by Hogwarts headmaster Albus Dumbledore dedicated to fighting Lord Voldemort and his followers, the Death Eaters. From the members of the Order, Harry and the others learn Voldemort is seeking an object he did not have prior to his first defeat and assume this object to be a weapon of some sort. Harry learns the Ministry of Magic, led by Cornelius Fudge, is refusing to acknowledge Voldemort's return because of the panic and chaos doing so would cause. Harry also learns the Daily Prophet has been running a smear campaign against him and Dumbledore.
