Question juridique clé
Whether the dental injury caused by a hazelnut shell fragment in birchermuesli qualifies as an accident under Art. 9(1) OLAA.
Solution extraite
Yes. The insured could not reasonably expect a leftover shell fragment in a meal he had prepared himself, and the file did not show that the tooth was so weak that it would have failed under normal pressure.
Motifs extraits
An extraordinary external cause was admitted because the shell fragment was not foreseeable in the meal as prepared, and no pre-existing dental fragility excluded accident character.
