Question juridique clé
Whether notifying an office tax assessment before the expiry of the granted deadline complies with good faith and the applicable procedure.
Solution extraite
No. Early notification of the office assessment was incompatible with the principle of good faith where the authority had granted a deadline extension.
Motifs extraits
By granting an extension, the authority created a legitimate expectation that the deadline would be respected. Notifying the assessment before that deadline expired undermined that expectation and was therefore inconsistent with constitutionally protected good faith.
