Some laws cannot yet be entirely abrogated in a current political situation, though permitting grave injustices against some individuals; for example, unborn and/or disabled individuals. In supporting the passing of new ‘imperfect’ laws that protect only some of those who now lack protection, do we ourselves discriminate unjustly against those remaining unprotected? Or does that depend on factors such as our intentions – including what we intend that others intend? How may we collaborate with colleagues who intend, and perhaps explicitly (...) defend, the continuation of remaining, closely-related injustices, although they are willing to join us in trying to improve some aspects of the status quo? This paper explores the moral constraints on our attempts to extend the law’s protection to some, but not to all, of those individuals currently deprived of such ­protection and at risk of serious harm.
