Key legal question
Whether the appellant had standing to challenge the dismissal of the claims against Y________ SA
Extracted holding
The appellant had no appealable legal interest in the dismissal of the claims against Y________ SA because the solidarity rule allowed the injured third party to claim the full loss from the other liable holder.
Extracted reasoning
Under Art. 60(1) LCR, the injured non-holder may pursue the full damage against any liable vehicle holder; the release of one insurer does not affect the pending claims against the appellant.
