Questão jurídica principal
Whether the 6 March 2000 pension calculation had become final for the period from 1 April 1997.
Decisão extraída
No partial res judicata existed for the pension amount; after the earlier judgment and the later earlier start date, the pension had to be recalculated from the beginning.
Fundamentação extraída
The dispute always concerned the pension relationship as a whole, not isolated calculation factors; those factors were not independently final before the whole dispute was finally decided.
