Questão jurídica principal
Whether a legally ordered forced affiliation to the substitute pension institution could be terminated by a later retroactive affiliation to another pension foundation without proper notice.
Decisão extraída
No. A lawful forced affiliation remains in force until it is properly terminated in accordance with the applicable notice rules; a later new affiliation does not by itself end it.
Fundamentação extraída
The substitute institution has sovereign powers only for the forced affiliation and related public-law matters, while the affiliation relationship itself is otherwise governed by private law. Since the respondent did not comply with the contractual termination rules attached to the affiliation order, the relationship continued beyond 31 December 2010.
