Questão jurídica principal
Whether a constitutional complaint against a decision with two independent grounds must challenge both grounds under Art. 90(1)(b) OG.
Decisão extraída
Yes. To show unconstitutionality, the complaint had to demonstrate that both independent reasons were arbitrary; since only one was attacked, the complaint was insufficient.
Fundamentação extraída
A decision based on two separate grounds is unconstitutional only if both are arbitrary. If one ground stands, the decision stands as a whole. The complaint failed to engage with the second ground and therefore did not satisfy the duty to state reasons.
