Social security agency corrected classification error retroactively without refunding benefits paid to the employer.

The Supreme Court overturned a lower court decision that had incorrectly classified a joint-stock company as a socialized enterprise for social security purposes. The employer argued that its majority capital was held by housing cooperatives, but the Court found that foreign ownership rendered it a foreign-invested company under specific statutory definitions. Consequently, the social security agency was permitted to issue a new decision correcting the classification without requiring the employer to repay benefits previously paid.
