A landmark assisted-dying case will put newly appointed U-S Chief Justice John Roberts to the test today.
It's a key test of states' rights versus federal authority.
The Bush administration claims Oregon's assisted-dying law allows the illegitimate use of controlled substances. But Oregon Solicitor General Mary Williams says a 2001 directive by then-U-S Attorney General John Ashcroft infringes on the right of states to regulate medical practices Williams says it would turn the controlled substances act into a "controlled medical practices act" and make the U-S attorney general "a one-person national medical board."
Williams and others say previous rulings by the high court have upheld states' rights.
