Prominent on the surface of any case held to involve a political question is found
- a textually demonstrable constitutional commitment of the issue to a coordinate political department; or
- a lack of judicially discoverable and manageable standards for resolving it; or
- the impossibility of deciding without an initial policy determination of a kind clearly for nonjudicial discretion; or
- the impossibility of a court's undertaking independent resolution without expressing lack of the respect due coordinate branches of government; or
- an unusual need for unquestioning adherence to a political decision already made; or
- the potentiality of embarrassment from multifarious pronouncements by various departments on one question.
