In _Harry Potter and the Order of the Phoenix_, Mrs. Figg implies Dumbledore opposed the Reasonable Restriction of Underage Sorcery act.

But the Law was passed in 1874, before Dumbledore's birth:
> As you know, underage wizards are not permitted to perform spells outside school, and further spellwork on your part may lead to expulsion from said school (Decree for the Reasonable Restriction of Underage Sorcery, 1875, Paragraph C).

So what did Mrs Figg mean by 'this is exactly what Dumbledore was afraid of', which sounds like he opposed the law?
