JURISDICTION OF THE SUBJECT MATTER.
The District Court was uncertain whether our cases
withholding federal judicial relief rested upon a lack of
federal jurisdiction or upon the inappropriateness of the
subject matter for judicial consideration-what we have

asserted can be judicially identified and its breach judicially determined, and whether protection for the right
asserted can be judicially molded. In the instance of
lack of jurisdiction the cause either does not "arise under"

that section; or the cause is not one described by any
jurisdictional statute. Our conclusion, see pp. 208-237.
