Key legal question
Whether the BVG contribution claim for the period 1985 to 31 July 2000 was time-barred
Extracted holding
The claim was not time-barred; limitation began with the compulsory affiliation decision of 23 August 2005, so the debt collection initiated in May 2007 interrupted the five-year period.
Extracted reasoning
For compulsory affiliation under Arts. 11 and 12 BVG, contributions arise only once the affiliation relationship is established by the affiliation order; before that, no due claim exists and no limitation period can start.
