Under Substantive maritime law, is the only basis for State and Federal concurrent subject matter jurisdiction, pursuant to 28 USC § 1333, admiralty and maritime jurisdiction?

2. If a civil court is a maritime court subject to maritime services, transactions, and other maritime matters, and the State abuse the process for what it was meant for in violation of the Fourteenth Amendment, therefore lacking subject matter jurisdiction to accept the plea in the case?

3. Does the concurrent jurisdiction make the trial court essentially a Federal court, under the principles of Federalism, therefore allowing one's other constitutional rights to be free from governmental action and one's Fourteenth Amendment privilege and immunity rights?
