Which powers are easier to challenge expressed powers or implied powers And why?

Implied powers are generally easier to challenge than expressed powers because they are not explicitly stated in the Constitution, leading to more interpretation and debate about their scope and limits. Since implied powers derive from the Necessary and Proper Clause, their application can vary based on differing judicial interpretations and political contexts. This ambiguity allows for greater contention in courts and among lawmakers regarding their legitimacy and extent. In contrast, expressed powers are clearly defined, making them more straightforward to uphold or contest.
