Javier Alcalde, International Catalan Institute for Peace (ICIP) has published Linguistic Justice: An Interdisciplinary Overview of the Literature as Amsterdam Working Papers in Multilingualism #3 27-96 (2015). Here is the abstract.
This report aims at offering an interdisciplinary analytical overview of the literature on the notion of “linguistic justice” and more generally fairness in multilingual contexts. It focuses the biggest part of its attention on political philosophy, but it presents also several contributions from economics, sociolinguistics, interlinguistics and law. The purpose of this report is neither to assess the internal consistency of alternative (and often contrasting) theories, nor to try to find a common ground among them. Its goal is to emphasize the policy recommendations that derive from different approaches. The report also discusses how different theories or approaches to linguistic justice have been applied to the case of the management of multilingualism in the European Union.Download the article from SSRN at the link.
