Question juridique clé
Whether the cantonal reduction of party compensation in the BVG case was arbitrary.
Solution extraite
The reduction was not arbitrary; the cantonal court could rely on the procedural features of social insurance litigation and on a customary hourly rate of CHF 200.
Motifs extraits
Cantonal law governs party compensation in BVG cases. Federal review is limited to arbitrariness. The investigation principle can ease counsel's work, and a fee based on a court-standard hourly rate is not manifestly untenable; the accepted workload was also not arbitrary.
