On Civil Rights: Concurred on allowing federal ObamaCare subsidies

The ruling, the 2nd case in which the justices have decided in favor of the Affordable Care Act, preserves benefits for an estimated 6.4 million Americans & deals a crippling blow to the law's Republican opponents, who have attempted to undermine it since its passage in 2010.

The law's architects claimed that subsidies were always meant to be distributed through both federal and state channels, and that the goal of the law was to cover all Americans. The Supreme Court agreed. Roberts said [forbidding federal subsidies] "would destabilize the individual insurance market, and likely create the very 'death spirals' that Congress designed the Act to avoid."
