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.
