In the case of R (Watson) v Secretary of State for the Home Department & Anor (Extant appeal: section 94B challenge: forum)  UKUT 165 (IAC), the UTIAC imparted the following guidance:
(1) Where an appellant’s appeal has been certified under section 94B of the Nationality, Immigration and Asylum Act 2002 and the appellant has been removed from the United Kingdom pursuant to that certificate, the First-tier Tribunal is the forum for determining whether, in all the circumstances, the appeal can lawfully be decided, without the appellant being physically present in the United Kingdom. The First-tier Tribunal is under a continuing duty to monitor the position, to ensure that the right to a fair hearing is not abrogated. In doing so, the First-tier Tribunal can be expected to apply the step-by-step approach identified in AJ (s 94B: Kiarie and Byndloss questions) Nigeria  UKUT 00115 (IAC).
(2) If the First-tier Tribunal stays the appeal proceedings because it concludes that they cannot progress save in a manner which breaches the procedural rights safeguarded by Article 8, then it is anticipated the Secretary of State will promptly take the necessary action to rectify this position. If this does not happen, then an application for judicial review can be made to the Upper Tribunal to challenge the Secretary of State’s decision and compel him to facilitate the appellant’s return.
(3) If the First-tier Tribunal decides that the appeal process is Article 8 compliant, the Tribunal’s substantive decision will be susceptible to challenge, on appeal to the Upper Tribunal, on the ground that the Tribunal was wrong so to conclude.
