Denying New Zealand's prisoners the right to vote is inconsistent with the Bill of Rights.
That's according to a ruling released today by our highest court, the Supreme Court.
Jailhouse lawyer Arthur Taylor has fought through New Zealand's highest courts against a 2010 law made by the then-National Government, which banned all prisoners from voting.
Prisoners could previously vote in elections if they were incarcerated for less than three years.
The declaration alone, however, doesn't require Parliament to repeal the voting ban.
Justice Minister Andrew Little says the government isn't sure yet how they will address it.
