Unenumerated rights are legal rights inferred from other rights that are implied by existing laws, such as in written constitutions, but are not themselves expressly coded or "enumerated" within the explicit writ of the law. Alternative terminology sometimes used are: implied rights, natural rights, background rights, and fundamental rights. Unenumerated rights may become enumerated rights if they necessitate the systematization of positively enumerated rights anywhere laws would become logically incoherent, or could not be adhered to otherwise. Examples of this include federal systems where constituent member constitutions have to be interpreted in relation to their membership in the federal whole, adjudicative of whether authority is rightfully devolved or more rightly federative. This term may be used loosely to mean any natural or intrinsic rights (such as rights innate to each individual or inherent to mankind) that are without expression or instance of articulation. Implied rights in Australian constitutional law Implied rights are the political and civil freedoms that necessarily underlie the actual words of the Constitution but are not themselves expressly stated directly in the Constitution. Since the 1990s, the High Court has discovered rights which are said to be implied by the very structure and textual form of the Constitution. Chief amongst these is an implied right to freedom of communication on political matters, which was first recognised in Nationwide News Pty Ltd v Wills. In addition, some protections of civil liberties have been the result of the High Court's zealous attempts to safeguard the independence of, and confidence in, the federal judiciary. A good example of this can be seen in Kable v Director of Public Prosecutions (NSW), in which the High Court struck down a criminal law passed by the New South Wales Parliament that was directed at a single, named individual in a similar manner to a bill of attainder.
