Kernrechtsfrage
Whether the insurer remained liable for accident benefits for complaints persisting from 1 December 2008 onward.
Extrahierter Entscheid
The accident of 8 November 2007 most likely caused only a temporary aggravation of a pre-existing degenerative lumbar condition; the status quo sine was reached by the end of October 2008, so no further liability existed.
Extrahierte Begründung
The court relied on the polydisciplinary Y.________ expert report, found it convincing and consistent, and held that the accident did not produce an objectively verifiable structural spinal lesion or a qualifying worsening of the degenerative findings.
