Beatrice:

I think that this was answered in HBP.  That the MoM can detect
magic, but they cannot necessarily detect who is performing it. The
first possibility is that the MoM has no way of knowing if Harry
performed this accidently as we know can happen with unschooled
wizards or if it was the act of someone else.

Second, Hagrid tells us in SS/PS that Dumbledore has given him
permission to use magic in order to locate Harry.  I suspect that
this did not mean that Hagrid was given a special permit by the MoM ,
but rather that DD fixed it in someway that Hagrid would be able to
use magic without being detected.  This would also explain why the
Accidental Magic Reversal Squad (I think the title may not be
accurate, but I don't have my texts) did not appear to correct the
spell.

Third, (this is a thought that has just occured to me this moment) is
it possible that there is more to the shack on the rock in the sea
than meets the eye?  Could a wizard live there with a house that is
hidden?  Like Grimmauld place or Hogwarts?  Could the shack be near
Azkaban? Magically protection could make it very difficult to detect
Hagrid's spell, as would the presence of one or more qualified
wizards.

Finally, perhaps it is just an inconsistancy in the text.  It isn't
as if we don't have other incidents where JKR has violated the rules
of her own universe.
