A group called Human Life of Washington has filed suit to challenge Washington laws purporting to require disclosure of certain issue advocacy activity. 

In a recently filed federal lawsuit, Human Life of Washington argued that it shouldn’t have to register with the state as a political action committee, because it wants to sponsor ads about the issue of assisted suicide — not ones explicitly about Initiative 1000.

The group says its free speech rights are being violated by a state law that requires political action committees to register and disclose their donors.

Initiative 1000, which mirrors a 1997 Oregon law upheld by the U.S. Supreme Court, would allow terminally ill people to obtain lethal prescription drugs for ending their own lives.
