Key legal question
Whether the refusal to admit the employee's promotion claim was discriminatory or unequal treatment based on age.
Extracted holding
The refusal was objectively justified by pension-fund financing concerns and was not discriminatory.
Extracted reasoning
Age-based differentiation is not prohibited as such; it requires specific justification. Here, the promotion near retirement would create unfunded pension burdens under a defined-benefit scheme, and the measure was transitional in the context of pension reform and fund consolidation.
