Question juridique clé
Whether the appellants could rely in good faith on the appeal instruction and municipal publication date when calculating the deadline.
Solution extraite
Yes. The wording of the government decision allowed the appellants to await publication before appealing, and their interpretation was not a grave mistake.
Motifs extraits
Under the principle of good faith, an erroneous or misleading appeal instruction must not prejudice a party. Here, the dispositive wording, read together with the relevant statutory context, was ambiguous enough to support the appellants' interpretation. They were not required to investigate doctrine and case law beyond the statute, and no serious negligence could be attributed to them or their lawyer.
