What concept is closely related to the implied powers?

The concept closely related to implied powers is the elastic clause, also known as the Necessary and Proper Clause, found in Article I, Section 8 of the U.S. Constitution. This clause grants Congress the authority to enact laws that are not explicitly listed in the Constitution, as long as they are deemed necessary to carry out its enumerated powers. This flexibility allows the federal government to adapt and respond to new challenges over time.
