 As for its capacity to deal with coordination problems, it is uncertain how far deference to authority is really needed here. The extent to which people need authoritative guidance to secure cooperation varies with context, and law can solve some problems of cooperation simply by providing information or by restructuring incentives (see Green 1988: 89–157). That suggests that NJT covers only a narrow range of legitimate state activity. But in another way, NJT seems too broad. We do not think that political authority should be acknowledged whenever the rulers can better ensure conformity to right reason. There are matters that are too trivial or otherwise inappropriate for political regulation. So perhaps some sort of threshold condition must first be met, and NJT should be confined to issues of general social importance. (Raz’s view has had a pervasive influence in the debate, generating a vast literature. Recent works that engage with it include Shapiro 2002; Perry 2012; Enoch 2014; Macklem 2015.)
