Question juridique clé
Whether the constitutional complaint against the refusal of full tax remission is admissible
Solution extraite
No admissible constitutional complaint lies because, under Aargau law, there is no justiciable entitlement to tax remission and therefore no legally protected interest under Art. 115 lit. b BGG.
Motifs extraits
Appeals against decisions on tax remission are excluded from ordinary public-law appeal; the subsidiary constitutional complaint is limited to violations of constitutional rights. The general prohibition of arbitrariness does not itself create a legally protected interest. The relevant cantonal provisions confer broad discretion rather than a subjective right.
