Supreme Court allows pension claim by recognizing prior cooperative work periods under social security regulations.

The Supreme Court quashed the appellate court's decision denying Nina B.'s pension claim based on her cooperative work history. The lower court incorrectly applied a regulation requiring continuous social security coverage to count pre-regulation periods, ignoring the regulation's explicit intent to include such past work. The Supreme Court ruled that the regulation's purpose was to integrate these periods into the insurance record regardless of subsequent coverage status.
