Law and Marxism: a general theory, by E.B. Pashukanis, was published in English in 1978, with an introduction by Chris Arthur. The copy I have was reprinted by Pluto Press in 1989. Critique 7, from 1976 carries an introduction to Pashukanis by Arthur, i.e. before the translation was published. There is a response from Steve Redhead in Critique 9.
