Key legal question
Whether a further appeal in public law matters was available against refusal to renew the residence permit and the removal order.
Extracted holding
No. The case concerned a residence permit and removal order for which no federal or treaty-based entitlement was shown, so the public-law appeal was unavailable.
Extracted reasoning
Without a legal entitlement to the permit, and with removal expressly excluded from that remedy, only the subsidiary constitutional complaint could be considered.
