Congress is misinterpreting their power regarding Federal Courts. Congress choosing to disallow certain cases to be cited in future rulings by Federal Courts is a violation of the separation of powers. Not only should Congress not do this they cannot legitimately do this. And if they choose to do this, it will be the start of a slippery slope within which our country falls into the abyss. Don't politicize our Courts. They may be the only saving grace this country has left.
