I'm pretty sure that it is the executive branch.
Incorrect, the judicial system determines whether the laws enacted by the senate/house and approved by the executive are constitutional.
No, the judiciary branch decides if a law is fair
I would say the Judicial Branch.
The United States Supreme Court.
To my knowledge it must be the Judicial Branch because the judicial branch carries the Supreme Court and their ones who decides if a law is constitutional.
Because if it's not fair then Congress will not approve it, so Congress decides if it's fair and right and if it goes by the Constitution.
Article I of the Constitution describes the structure of the legislative branch of government we know today.
Judicial makes sure they follow the Constitution and that they are fair.
No branch does this.The Judicial branch ... specifically the Supreme Court ... can rule on whether laws are compatible with the US Constitution or not, and overturn laws which are not (the US Constitution is "above the law" in that all laws passed by the Legislative branch and ratified by the Executive branch are strictly subordinate to it, and in any conflict between the two, the Constitution takes precedence), but this is only peripherally related to "fairness".
The System under which a government agency decides fair shares is Rationing
