Preparatory Action, or Prejudicial Action [in Law]

Preparatory Action , or Prejudicial Action [in Law]
is that which grows from some Doubt in the Principal; as suppose a Man sue a younger Brother for Land, descended from his Father, and Objection is made that he is a Bastard, the Bastardy must first be try’d, and thence the Action is called Prejudicial.
