The passage below describes a U.S. Supreme Court decision In 1940, the Texas Democratic Party refused to give an African American man a ballot to select candidates to run for Congress and governor. In finding this action unconstitutional "… this Court is not constrained to follow a previous decision which…, involves the application of a constitutional principle, rather than an interpretation of the Constitution to evolve the principle itself." Source: Smith v. Allwright (1944) What does this court decision illustrate? (Hard)

One of the most well-known powers that is attributed to the Supreme Court is the ability to judicially review any act, considered unconstitutional, that is not written in the federal constitution. This power is being illustrated in the text above.

This is because the text shows how the supreme court, judicially revised the decision that the black population could receive ballots to cast votes for candidates for governor. The supreme court states that the inclusion of the black vote is not described in the constitution and for that reason, the black people 's voting permission may undergo judicial review.
