Life in the ultra-Orthodox Jewish community of Lev Tahor is supposed to be simple: the rules for dress, diet, schooling, marriage and worship are clearly defined and closely followed. But last November, in the middle of the night, about 200 members of the sect fled their homes in Quebec to start a new community in Chatham, Ontario, amid allegations of child neglect. Now the sect is fighting to keep more than a dozen children that a Quebec court ordered removed from their families. Their ongoing legal battles are raising an old dilemma: when does a group’s right to religious freedom get trumped by society’s obligation to protect children?
