Key legal question
Whether the constitutional complaint was admissible despite no legal entitlement to renewal of the residence permits.
Extracted holding
No. Because the applicants had no enforceable right to renewal, they could not challenge the substantive refusal by constitutional complaint.
Extracted reasoning
Art. 13 BV and Art. 8 ECHR did not confer a residence-permit entitlement on the applicants in these circumstances; therefore only the extraordinary constitutional complaint was available, and not on the merits.
