The Federation of Saskatchewan Indian Nations is threatening to take the Harper government to court over what it says are violations of treaty rights in Bill C-45.

The FSIN says the omnibus bill threatens First Nations rights in a number of areas including health, education, lands and resources.

The organization adds it is willing to launch constitutional challenges against the federal government as high as the Supreme Court of Canada over these treaty violations and possibly even higher to the United Nations if necessary.

FSIN Chief Perry Bellegarde says in a released statement that the Harper government emphasizes the Canadian Constitution on one hand but then disrespects the constitution on the other when it comes to the rights of First Nations people.

First Nations people across the country have been rallying against the federal government throughout the month of December in a series of public protests called Idle No More.
