Social security court jurisdiction changes do not invalidate proceedings if the original branch represented the defendant.

The Supreme Court dismissed the cassation appeal regarding a social security benefit denial, ruling that changes in the Social Insurance Institution's branch jurisdiction did not invalidate the administrative proceedings. The appellant argued the wrong branch represented the defendant after a 1996 decision, but the court noted the original branch had issued the contested decision and represented the defendant throughout the first and second instances. The court held that such administrative reorganizations cannot retroactively invalidate proceedings where the competent organ was properly represented at the time of the decision.
