This year's problem relates to the Birss Butterfly Cake, a delicious sticky ginger cake decorated with frosting and Burrellshire Brandy Butter Icing.

Floyd's Kitchins, the makers of the Birss Butterfly Cake, brought a copyright action against supermarket Greenland in relation to its 'knockoff' cake. That claim failed. It was held by Chen Wishart J that the Birss Butterfly Cake is not an artistic work under the Copyright Act.

The Erewhonian Burrellshire Brandy Association successfully argued there was passing off by Greenland using a low-booze icing and calling it 'Burrellshire Brandy Butter Icing'. Its claim under the Protected Geographical Indications Act failed, however.
