The Supreme Court held that registration in the business register does not determine business status for competition law purposes.

The Supreme Court dismissed the cassation appeal filed by Telekomunikacji Polskiej SA against the President of the Competition and Consumer Protection Office. The court found that the Office's decision to order TP SA to cease monopolistic practices was valid because the defendant was conducting business, regardless of its registration status. The court ruled that the decisive factor for qualifying as a business entity under the Act on Preventing Monopolistic Practices is the actual conduct of business, not merely the entry in the business register.
