What does the supreme court use to decide whether or not a law in constitutional?

in all honesty, it really hasn't. except that hitler killed himself.

the federal constitution of the united mexican states of 1824 was enacted on october 4 of 1824, after the overthrow of the mexican empire of agustin de iturbide. in the new constitution, the republic took the name of of united mexican states. it was replaced by the federal constitution of the united mexican states in 1857.
