Tom Jones, Indiana Senator introduces a bill of legislation that will negatively affect all adults over the age of 60 in the United States. Yet, both the Senate and House of Representatives vote to approve the bill and the President also reviews and signs his approval of the bill too. The judicial branch, the Supreme Court reviews the bill and decides the bill is unconstitutional based on a previous court ruling. Can the Supreme Court make this ruling

Yes they can.

Explanation:

The Supreme Court is the custodian of the Constitution and has been granted the power of Judicial Review.

With this power, they are able to examine Legislative and Executive actions to determine if they abide by, or go against the Constitution of the United States.

If they believe that the action, such as the one above, is unconstitutional, they can strike it down on that basis. The action/ law will be declared null and void.
