I have the following question:
As we very well know, the Ministry of Magic can detect magic in proximity of minors (like the hovercharm in Harry Potter and the Chamber of Secrets or the Patronus in Harry Potter and the Order of the Phoenix), but not the caster of the magical spell. So why does the ministry not accuse Harry of doing magic in the following scenes?
- Goblet of Fire: Mr. Weasly blows up the Dursleys' living room
- Order of Phoenix: Tonks helps Harry with his luggage using several magic spells
(One would think that this is a rather important fact, as Harry has to face the court due to the prior Patronus-spell)
I think there was one more scene, but I cannot remember it at the moment
