Questão jurídica principal
Whether the appeal was admissible and whether a legal entitlement to renewal of the residence permit existed.
Decisão extraída
No legal entitlement existed on the facts, so the public-law appeal was not available to the extent it depended on discretionary immigration law; any constitutional complaint could only concern procedural rights.
Fundamentação extraída
Under the ANAG, residence permits are generally discretionary unless a special federal norm or treaty grants a right. After the divorce, the appellant no longer had a claim to renewal based on his first marriage, and his residence permit did not itself create a family reunification entitlement.
