Key legal question
Whether the public law appeal was admissible under the former procedural law.
Extracted holding
Because the challenged decision predated 1 January 2007, the former procedural law applied; the filing was treated as a public law appeal, not a nullity appeal.
Extracted reasoning
Under Art. 132(1) LTF, the new Federal Supreme Court Act applies only to decisions issued after its entry into force. The appellant attacked the findings of fact, which excluded a nullity appeal.
