 There is also growing awareness at a theoretical level of the importance of expressive values in the law (McAdams 2015). It is something of a loss that the schema developed by Summers and his collaborators, dividing legal techniques into “grievance-remedial”, “penal-corrective”, “administrative-regulatory”, “public-benefit conferral”, “facilitator of private arrangements”, appears to have fallen largely into disuse (Summers et al. 1986). For it allowed various areas of potential legal concern to be examined against a background of various legal techniques, coercive and beyond. Rawls’ question of how far such techniques should be subject to public reason is a further issue that might helpfully be pressed.
