If the interests of justice were applied here, and nothing else,
the courts should uphold the law because in order to justify overturning this portion of it one would have to believe with reasonable certainty that the Congress that passed this law intended the subsidies to ONLY be available to residents of states that set up exchanges,
and, conversely, that Congress intended the subsidies to be unavailable to residents of the other states.
That is not a conclusion that one can reasonably reach.
So, in order to be just, they have to ignore what the law says and go with what you believe.
Makes sense, until you consider the fact that the same rule could apply to other things. Imagine a Republican court ignoring the law that says that equal rights belong to everyone and going with what they believe, that justice demands that they restrict the rights of people who don't agree with the Republican agenda. My guess is that you would find that outrageous, even though it fits nicely into your definition of justice.
People need to learn to think before you post.
