Cook County Republican Party v. Sapone

Dist. Ct. lacked subject-matter jurisdiction to act on lawsuit filed by plaintiff-Republican Party seeking declaration that it was not required to seat defendants-two elected ward committeemen on plaintiff’s central committee. Instant lawsuit, in which plaintiff claimed that defendants were ineligible to be seated on committee because each defendant had voted in Democratic Party primary within last eight years, rested only on state law and plaintiff’s rules, and instant litigants were not of diverse citizenship.
