Asked and answered. It doesn't have to be written out in explicit words for you to read. It follows from the basic function of the court. Courts have to resolve cases where two different laws are in conflict with each other. If a statute is in conflict with the Constitution, the Constitution wins, and the court will decide that the statute is unenforcible. This is inherent to the process, it can't be otherwise.
According to you, the judiciary can usurp the constitutional authority of the president because the judiciary is a co-equal branch of government.
If that’s the case, then a judge can stop the president from sending troops into Iraq and instead send the troops to Syria, because judges are a co-equal branch of government.
If that’s true, than a congressman from Idaho can issue an opinion that Roe v Wade is illegal ,and overrule the USSC because that congressman is a co-equal branch of government.
Please continue. I’m amused.
