Question juridique clé
Whether P.________ qualified as a de facto organ liable under Art. 52 LAVS for unpaid social contributions
Solution extraite
The cantonal court relied too heavily on commercial-register signature power and payroll-related administrative acts; liability requires proof of an actual, durable management role at top level.
Motifs extraits
A de facto organ is only someone who effectively assumes superior decision-making powers beyond routine administration. The necessary factual findings on P.________'s real role were missing.
