Question juridique clé
Whether the constitutional complaint was admissible despite the parallel appeal and the subsidiarity rule
Solution extraite
No. Because the alleged error in fact-finding and attribution of knowledge could be raised in the ordinary appeal, the constitutional complaint was barred by subsidiarity.
Motifs extraits
The alleged incorrect attribution of R.'s knowledge concerned either an obvious factual mistake or a matter governed by federal law. In both respects, the ordinary appeal was the proper remedy, so the constitutional complaint could not be used subsidiarily.
