"I sent him an owl about that just last week. If I've told him once I've told him a hundred times: Carpets are defined as a Muggle Artefact by the Registry of Proscribed Charmable Objects, but will he listen?"
-- Arthur Weasley to Mr Crouch about Ali Bashir's flying carpets (GF7)
With the International Statute of Secrecy in force, this list is meant to prevent wizards putting spells on everyday Muggle items. This is to prevent the Muggles getting hold of the charmed objects by accident. The Register is enforced by the Misuse of Muggle Artifacts Office (GF7) and the proscribed objects include biting teasets and kettles (CS3), flying carpets (GF7, JKR-W1), hiccoughing toasters (OP7) and flying cars (CS3).
