In A Global Political Morality, Michael J. Perry addresses several related questions in human rights theory, political theory and constitutional theory. He begins by explaining what the term 'human right' means and then elaborates and defends the morality of human rights, which is the first truly global morality in human history. Perry also pursues the implications of the morality of human rights for democratic governance and for the proper role of courts - especially the US Supreme Court - in protecting constitutionally entrenched human rights. The principal constitutional controversies discussed in the book are capital punishment, race-based affirmative action, same-sex marriage, physician-assisted suicide and abortion.
