Court dismisses claim that setting high pay for slightly increased duties violates solidarity insurance principle.

The court dismissed the plaintiff's claim arguing that a significant pay increase for marginally expanded duties violated the solidarity principle of the insurance system. The plaintiff contended that such a disparity undermined the collective nature of the insurance scheme, while the employer argued the adjustment reflected genuine performance improvements. The court ruled that the specific circumstances did not constitute a breach of the solidarity principle, thereby upholding the remuneration decision.
