Questão jurídica principal
Whether the subsidiary constitutional complaint in the tax-remission matter was admissible despite lack of ordinary federal appeal
Decisão extraída
Only the subsidiary constitutional complaint was available because the dispute concerned tax remission and the ordinary federal appeal was excluded.
Fundamentação extraída
Under the unity of proceedings, procedural decisions follow the main matter; since Art. 83 lit. m BGG excludes the ordinary appeal in tax remission cases, only the subsidiary constitutional complaint could be filed.
