We're talking a system which had to be told by the courts that if the law requires to give somebody notice that the process to revoke citizenship was initiated, it can't count "we put the papers in their internal Home Office file" as "delivery of notice". We're talking the system of the Windrush scandal, which only after intense pressure cost the Home secretary her job, and which two following holders of the position haven't managed to actually effectively implement the measures promised to attempt to fix the damage done. Strong skepticism is sadly warranted.
