The response that best describes a check on the judicial branch’s power is "the judicial branch overruling the president’s executive order." This indicates the judicial branch’s ability to limit the powers of the executive branch, thereby serving as a check on the presidency.
In the context of checks and balances among government branches:
- Congress overriding a presidential veto is a check on the executive branch, not the judicial branch.
- The judicial branch overruling the executive order directly limits presidential power.
- Congress initiating a constitutional amendment is a legislative check, but does not directly relate to judicial power.
- The president signing a bill into law is an exercise of executive power, not a check on the judicial branch.
Thus, the judicial branch's ability to overrule executive actions is the correct answer regarding a check on its power.
