Key legal question
Whether the cantonal court's 2006 judgment had res judicata effect barring the claim to benefits under the supplementary pension plan
Extracted holding
No. The earlier dispositif recognized liability in principle but did not finally decide whether the right arose from the mandatory scheme only or also from the supplementary regulation.
Extracted reasoning
The first judgment did not expressly exclude rights under the fund's regulations, and its reasoning only preferred the statutory regime as more favorable; therefore no material decision existed on supplementary benefits.
