Immigration – Asylum – Refusal of leave to appeal. Court of Session: Granting a petition for judicial review of a decision of the Upper Tribunal (UT) refusing the petitioner leave to appeal against a decision of the First Tier Tribunal, the court held that the immigration judge's approach to the assessment of the best interests of the petitioner's child raised an important point of principle or practice, and the UT judge's decision that there was 'no arguable legal error' was manifestly bad.
