A few days ago I wrote to a Finnish colleague that perhaps half of the academics at UK law schools were foreigners. Later on, I felt that I may have overstated this point. Therefore, I just looked at two universities (University of East Anglia and University of Oxford) and I tried to calculate the proportion of foreign academic lawyers. To clarify, I only considered full time staff and that I used the country of his or her first degree as the main proxy for the nationality of an academic.
Notes: The absolute figures are: UEA 16, 7, 3 and 1 and Oxford 45, 10, 19 and 3.
For German academic lawyers at UK law schools see already here.
