Prefeitos podem dar / receber pontos de casa? [duplicado]

Do Wiki de Harry Potter :

Teachers, as well as librarians have the power to award or deduct points from students. Prefects, the Head Boy, and the Head Girl can deduct points as well, but not from other Prefects. During the 1995–1996 school year however, members of the newly-formed Inquisitorial Squad were permitted to do so.

It is stated that prefects are allowed to dock points from students in Harry Potter and the Chamber of Secrets. However, this idea is diminished in Harry Potter and the Order of the Phoenix when it is stated that prefects are in fact not allowed to do so. In later editions, however, it seems that, with the exception of the Inquisitorial Squad, prefects can dock points only from their own house.

Além disso, do Léxico do Harry Potter :

Prefects are allowed to take points for infractions, but not from fellow Prefects.
NOTE: In the original version of OP, this was very confusing. It seemed from the text that Prefects were NOT allowed to take points, although Percy had clearly done so in book two. Rowling partially answered the question on her website, but it wasn't until the revision to the text (summer 2004) that the matter was resolved. Here are the original incorrect version and the updated, corrected version of the passage:

Old version:

• 'Afraid I'm going to have to dock a few points from Gryffindor and Hufflepuff,' he drawled.
  'It's only teachers who can dock points from houses, Malfoy,' said Ernie at once.
  'Yeah, we're prefects, too, remember?' snarled Ron.
  'I know prefects can't dock points , Weasel King,' sneered Malfoy. Crabbe and Goyle sniggered. 'But members of the Inquisitorial Squad -'

New version:

• 'Afraid I'm going to have to dock a few points from Gryffindor and Hufflepuff,' he drawled.
  'You can't take points from fellow prefects, Malfoy,' said Ernie at once.
  'I know prefects can't dock points from each other,' sneered Malfoy. Crabbe and Goyle sniggered. 'But members of the Inquisitorial Squad -'

Os monitores foram autorizados a atracar pontos sob o governo de Umbridge. Acredito que membros do Esquadrão Inquisitorial também possam ter conseguido pontos. Em Ordem da Fênix , vemos Draco recebendo pontos de Harry, Ernie Macmillan (também um prefeito), Ron (também um prefeito) e Hermione (também uma prefeita). Pode ser que apenas membros do Esquadrão Inquisitorial possam receber pontos. Isso explicaria a discrepância entre Câmara Secreta e Ordem da Fênix .

ETA: Sim, foi o Esquadrão Inquisitorial que poderia levar pontos em Ordem da Fênix

‘The Inquisitorial Squad, Granger,’ said Malfoy, pointing towards a tiny silver ‘I’ on his robes just beneath his prefect’s badge. ‘A select group of students who are supportive of the Ministry of Magic, hand-picked by Professor Umbridge. Anyway, members of the Inquisitorial Squad do have the power to dock points ... so, Granger, I’ll have five from you for being rude about our new Headmistress. Macmillan, five for contradicting me. Five because I don’t like you, Potter. Weasley, your shirt’s untucked, so I’ll have another five for that. Oh yeah, I forgot, you’re a Mudblood, Granger, so ten off for that.’
