Can prefekter tar poäng från hus?

J.K. Rowlings webbplats officiella FAQ # 40

Q: Can prefects take points or not? A prefect took points from Gryffindor in the Chamber of Secrets, and then there was a reference to prefects not being allowed to dock points. What are the rules?

Answer: Ron got it wrong in 'Phoenix', from which we deduce that he hasn't been a very authoritarian prefect thus far; he clearly hasn't been taking points from anybody.

There was some confusion about the point-taking ability of prefects after the original release of Harry Potter and the Order of the Phoenix. It had previously been stated in Harry Potter and the Chamber of Secrets that prefects could dock points, but in a scene in the first printing of Harry Potter and the Order of the Phoenix Ron Weasley, Ernie Macmillan, and Draco Malfoy all either state outright or imply that prefects are not allowed to take points. This was pointed out as a mistake, and subsequent printings had a slightly different version of the dialogue, making it clear that prefects can take points, just not from other prefects.

Bara spekulation, men kanske för att Percy var i Gryffindor fick han ta poäng ut ur sitt eget hus i straff, ungefär som när Harry var hotad med utvisning, var det McGonagall som höll det beslutet, och inte Snape. Jag föreställer mig skolan sätta det på plats så att prefekter inte missbrukade sin makt, men jag kan inte komma ihåg att detta uttryckligen anges i canon.

Prefects are allowed to take House points away from other students in their own house as a penalty for rule-breaking, but they are not allowed to take points from other prefects or students in other houses.

Förmodligen ändrades regeln. Eller kanske prefekter kunde bara ta poäng från sitt eget hus.
