Kernrechtsfrage
Whether the court had jurisdiction over the pension fund's claim and the request to lift the objection.
Extrahierter Entscheid
The court had subject-matter and territorial jurisdiction, and the claim was admissible.
Extrahierte Begründung
Disputes over pension fund claims against employers fall under Art. 73 BVG; the debtor's seat in Solothurn established territorial jurisdiction. The social insurance judge is also the competent ordinary judge for the debt enforcement objection issue.
