The Ban on Experimental Breeding was enacted in 1965 to regulate the growth of wizard-bred magical creatures. These include dangerous creatures such as Acromantula, Basilisks, and a fire-breathing chicken confiscated by Bob. It was written by the Magizoologist Newt Scamander, and is enforced by the Ministry of Magic's Department for the Regulation and Control of Magical Creatures. The punishment for violations of this law is handed down by the Wizengamot.
Behind the scenes
- Despite the ban, there have been instances where new creatures have been created without any mention of punishment. Two such cases would be the Blast-Ended Skrewts bred by Rubeus Hagrid in 1994, and the Pygmy Puffs bred by Fred and George Weasley as part of their WonderWitch product line. Given that Fred and George run a joke shop, it is possible that they obtained permission to breed the Pygmy Puffs - or, because they are not dangerous, there was no need to inforce the law - that there are certain unspecified exceptions or loopholes in the ban, or that enforcement may simply be lax.
