Kernrechtsfrage
Whether the son remained in education after 1 April 2008, so that the parents kept entitlement to child pensions.
Extrahierter Entscheid
No. The training character was not established with the required degree of probability; the son could have maintained substantial employment alongside the evening course.
Extrahierte Begründung
The course at Handelsschule KV Basel had training character, but child-pension entitlement also requires that education cause a materially reduced earning capacity. Because the timetable allowed about 80% employment, education did not itself explain the low earnings. The employment relationship and corporate ties pointed away from a genuine training contract.
