Kernrechtsfrage
Whether the shortened appeal period and fax notification violated the right to be heard, equality, arbitrariness prohibition, or fair trial guarantees.
Extrahierter Entscheid
No. Federal statutes cannot be reviewed for constitutionality, Article 6 ECHR does not apply to administrative mutual assistance, fax was only courtesy, and the appeal was timely from postal service.
Extrahierte Begründung
The appellants knew the file and had already commented twice; the fax did not start the deadline and they still filed a lengthy appeal and reply.
