some clan societies even claim that certain tartans are the personal property of a chief or chieftain, and in some cases they allow their clansfolk "permission" to wear a tartan. according to the scottish tartans authority — which is closely associated with the scottish tartan industry — the "balmoral" tartan should not be worn by anyone who is not part of the british royal family. even so, some weavers outside of the united kingdom ignore the "longstanding convention" of the british royal family's "right" to this tartan. the society also claims that non-royals who wear this tartan are treated with "great disdain" by the scottish tartan "industry".
