A Cart JR is a legal challenge by way of Judicial Review proceedings against a decision made by the Upper Tribunal (UT), Immigration and Asylum Chamber, to refuse permission to challenge a First-Tier Tribunal determination/decision, in circumstances where there is no further right of appeal to the Court of Appeal.  It is a challenge based on a ruling from the Supreme Court in a challenge brought by someone called Cart.

A Cart JR needs to be brought within 16 days of the UT decision, rather than 3 months, as is the case with most other judicial reviews, and, crucially, the 16 days start on the date on which the Upper Tribunal permission refusal was sent.

Following are various stages of CART JR to challenge the decision of the Upper Tribunal refusing permission to appeal to the Upper Tribunal:

On Papers Application To High Court For Permission To Apply For Cart JR
Application For Renewal Of Permission For Cart JR At An Oral Hearing In High Court
Substantive Cart JR Hearing In High Court Following Grant Of Permission
