There’s a second and updated edition out of James Hanratty’s memoir The Making of an Immigration Judge, available from Quartet Books. I reviewed the previous edition and found it a very interesting and revealing read.
The author tells me that he’s made significant amendments to this latest edition including “a substantial change in tone with sympathy for hard working and under paid lawyers”. He has also, in the meantime, served on the Windrush Lessons Learned Review, which I imagine will have imparted new insight. There are not many opportunities to get an insight into the mindset of the immigration judiciary and this is one.
More information on the changes since the last edition here.
