The bill (SB1335), approved 56-0 and modeled after a Utah law, would make it a felony for a married adult to marry a child. Other provisions are aimed at holding parents responsible for forced marriages of their children.

The sect split from mainstream Mormonism after the broader church renounced polygamy more than a century ago.
