Kernrechtsfrage
Whether the settlement permit could be revoked for a serious breach of public security and order despite long lawful residence.
Extrahierter Entscheid
Yes. The repeated violent and traffic offences, combined with the ineffectiveness of prior warnings, justified revocation under the statute.
Extrahierte Begründung
The court held that a serious breach may arise from repeated offences and from demonstrated unwillingness to comply with the legal order. Prior formal and informal warnings had no effect, indicating a high risk of future offending.
