 A reason for Rawls to defend this coordination requirement is that often coordination serves a more important concern, namely, the achievement of good consequences. It is often argued that civil disobedience can only be justified if there is a high probability that it will produce positive change, since only such change can justify exposing society to the risks of harm usually associated with civil disobedience – namely, its destabilizing and divisive potential and the risk that it could encourage lawbreaking or escalate into uncivil disobedience. In response to these challenges, one might question the empirical claims that civil disobedience is divisive and that it has the consequence of leading others to use disobedience to achieve changes in policy. One might also question whether it necessarily would be a bad thing if civil disobedience had these consequences. Concerning likelihood of success, civil disobedience can seem most justifiable when the situation appears hopeless and when the government refuses to listen to conventional forms of communication. Additionally, even when general success seems unlikely, civil disobedience might be defended for any reprieve from harm that it brings to victims of a bad law or policy. Tree-hugging, for example, can delay or curtail a clear-cut logging scheme and thereby prolong the protection of an ecosystem.
