Question juridique clé
Whether the insurer could deny ongoing UVG benefits for shoulder complaints after 31 August 2007
Solution extraite
The present medical file did not permit a final ruling on causation or on whether the status quo sine had been reached; a new independent shoulder expertise was required.
Motifs extraits
The competing medical opinions on causation were mutually contradictory and each insufficiently reasoned, so the evidentiary basis was inadequate under the social-insurance standard.
