A public planning application document concerning the alteration of the Constellation's terrace was falsified in December 2025, two weeks before the fire: a civil engineer's name appeared on it without his knowledge, as the project draughtsman lacked the diploma now required in Valais to sign plans. The engineer reported the matter to the police.
