Kernrechtsfrage
Whether the window was defective under the Product Liability Act because it lacked additional safety devices such as a catch/cleaning hinge
Extrahierter Entscheid
No defect was shown; the window met the justified safety expectations at the time it was placed on the market.
Extrahierte Begründung
The relevant risk arose only after a later manipulation: the tilt latch had been detached and was not reattached. The manufacturer need not foresee or secure against such non-typical post-market tampering or negligent maintenance.
