- Congress cannot delegate legislative power to agencies without declaring a policy or establishing a standard for the executive branch to follow.
- Think: delegating to the executive branch with no guideposts to follow.
- Congress must provide an intelligible principle to guide the agency's discretion.
- If invoked, the Non-Delegation Doctrine strikes down the entire legislative grant of power to the agencies.
- Contrast this with the MQD not invalidating the entire grant, just the action.
- Historically, SCOTUS has been very hesitant to invoke NDD.
- It hasn't been used to strike down a statute since 1935.
- Summation: Court does not allow agencies to delegate power to agencies without providing guideposts.
