Question juridique clé
Whether the filing could be treated as a constitutional complaint rather than an appeal in public law matters.
Solution extraite
The matter concerned remission of fees, i.e. a tax-like public charge, so ordinary public-law appeal was excluded; only a subsidiary constitutional complaint was available.
Motifs extraits
Art. 83 lit. m BGG excludes public-law appeal against decisions on remission of taxes/fees. The submitted title did not bind the Court.
