Supreme Court dismisses appeal regarding invalid power of attorney; general power signed by director is valid even if submitted as photocopy.

The Supreme Court dismissed the cassation appeal filed by Krzysztof K. against a disability pension decision involving the Social Insurance Institution. The appellant argued that the first-instance proceedings were invalid because the insurer's representative lacked proper authorization, claiming the submitted document was merely a photocopy dated only on the envelope. The court ruled that the general power of attorney, signed by the branch director and granted to a branch employee, fully met legal requirements, and submitting a photocopy did not violate procedural rules.
