Social security pension right upheld if continuous disability existed despite decision date evidence gaps.

The Supreme Court dismissed the case and remanded it to the Court of Appeal in Katowice for further proceedings. The insured, Michał C., challenged a decision denying an extension of his disability pension due to conflicting medical opinions regarding his diabetes-related condition. The court ruled that while the decision date is primary, later evidence proving continuous disability can validate the right if the condition was unbroken. Because the lower courts failed to sufficiently verify new medical documentation suggesting continuous incapacity, the matter required a fresh, thorough examination of the evidence.
