The Cambridge Centre for Animal Rights Law ran its first Essay Competition this year. Our competition title followed in the footsteps of the competition run in 1795 by the Vice-Chancellor of the University of Cambridge, when the question was: Anne liceat invitos in servitutem dare? Our Centre invited essays on the same question: Is it lawful to enslave the unconsenting? We have received a large number of excellent submissions and are delighted to announce the winners on our Essay Competition site, where you can also read the winning essays.
