from wiki:
Many freemen beliefs are based on idiosyncratic interpretations of
admiralty or maritime law, which the freemen claim govern the commercial world. These beliefs stem from
fringe interpretations of various nautical-sounding terms, such as
ownership,
citizenship,
dock, or
birth (berth) certificate. Freemen refer to the court as a
ship and the court's occupants as
passengers, and may claim that those leaving are "men overboard".

Freemen will try to claim common law (as opposed to admiralty law) jurisdiction by asking "Do you have a claim against me?" This, they contend, removes their consent to be governed by admiralty law and turns the court into a common law court, so that proceedings would have to go forward according to their version of
common law.
This procedure has never been successfully used.
