Kernrechtsfrage
Whether the cantonal complaint was timely despite the filing date appearing outside the 30-day period.
Extrahierter Entscheid
The complaint was timely because the statutory deadline was suspended during the summer recess under Art. 38(4) ATSG.
Extrahierte Begründung
The federal court applies the deadline-suspension rule directly in invalidity matters, and cantonal law did not provide an equivalent solution.
