supplemental jurisdiction
a court may entertain claims that could not, by themselves, invoke federal question jurisdiction or diversity jurisdiction if the claims arise from a common nucleus of operative fact as the claim that invoked original federal subject matter jurisdiction
A cross-claim may be asserted if
the claim arises from the same transaction or occurrence as the underlying dispute. If claim does not have an independent subject matter basis, may be asserted through supplemental jurisdiction.
permissive counterclaim
one arising out of a completely unrelated transaction
A permissive counterclaim must
have an independent jurisdictional basis.
A compulsory counterclaim need not
meet the jurisdictional amount requirement, as the court may hear it under its supplemental jurisdiction.
Removal is permitted only by
defendants.
