Telecom operator's refusal to sign interconnection agreements violates competition law, not just telecom law.

The Supreme Court dismissed the cassation appeal against a lower court ruling that upheld a fine against a telecom operator for refusing interconnection agreements. The operator argued that its conduct should be judged solely under telecom law, but the court found that blocking market entry for independent internet service providers also constitutes a restriction of competition under consumer protection law. Consequently, the court remanded the case to the appellate court to properly assess the fine's justification and the nature of the anti-competitive behavior.
