Yeah, like this one (below) on the same issue? The federal courts are into POWER, and liberal politics, not states rights.
Washington State
On January 25, 1994, Compassion in Dying initiated a legal challenge of Washington State's prohibition against assisted suicide, RCW 9A.36.060. On May 3, 1994, Federal Judge Barbara J. Rothstein rendered a decision declaring the law unconstitutional. On March 9, 1995, a 3-Judge Panel of the Ninth District Court of Appeals overturned the District Court (2-1). On March 6, 1996 the Ninth District Court (en banc) reinstated the District Court ruling.
Different case. Also notice it wasn't the federal government attempting to undermine the state law using federal law.
