A sharply divided Montana Supreme Court has ruled that forcing a Hutterite religious colony to pay workers' compensation insurance for jobs outside the commune is not an unconstitutional intrusion into religion.

The 4-3 decision upholds a 2009 law requiring religious organizations to carry workers' compensation insurance, which the Legislature passed after businesses complained they could not outbid the religious workers.

The Big Sky Colony of Hutterites in northwestern Montana sued, saying the law targeted its religion and infringed on its beliefs. Its members have no personal property and make no wages as part of their communal life, which is central to their religious beliefs, and a member can't make a claim against the colony or take money for himself without risking excommunication.

The Hutterites are Protestants similar to the Amish and Mennonites who live a life centered on their religion. But unlike the others, Hutterites live in German-speaking communes scattered across northern U.S. states and Canada. They are primarily agricultural producers but have expanded into construction with success because they can offer lower job bids than many private businesses.

Justice Brian Morris, writing for the majority, said the workers' compensation requirement does not interfere with the Hutterites' religious practices but only regulates their commercial activities like any other business.
