The civil caseload mix differs because federal and state law regulate different activities.

Evidence

Taken together, the tables reveal that, although federal and state trial courts both handle a wide range of civil cases, the mix of civil cases differs considerably.

Governmental actions and litigation priorities influence the character and extent of that litigation. — G. Alan Tarr, Judicial Process and Judicial…, 2253
