In one of the earliest freedom suits, Casor argued that he was an indentured servant who had been forced by Anthony Johnson, a free black, to serve past his term; he was freed and went to work for Robert Parker as an indentured servant. Johnson sued Parker for Casor's services. In ordering Casor returned to his master, Johnson, for life, the court both declared Casor a slave and sustained the right of free blacks to own slaves.
In 1653 John Casor, an African employed by Johnson, filed what later became known as a freedom suit. He said that he had been imported as a "seaven or eight yeares" indentured servant and that, after attempting to reclaim his indenture, he had been told by Johnson that he didn't have one. According to the civil court documents, Casor demanded his freedom. "Anthony Johnson was in a feare. Upon this his son in law, his wife and his two sonnes persuaded the said Anthony Johnson to set the said John Casor free."
Casor went to work for Robert Parker, an English colonist who, along with his brother George, later testified that they knew Casor had an indenture. One commentator said that Johnson may have feared losing his headrights land if the case went to court.
Anthony Johnson brought suit in Northampton County court against Robert Parker in 1654 for detaining his "Negro servant, John Casor," saying "Hee never did see any [indenture] but that hee had ye Negro for his life". In the case of Johnson v. Parker, the court of Northampton County upheld Johnson's right to hold Casor as a slave, saying in its ruling of 8 March 1655:
This daye Anthony Johnson negro made his complaint to the court against mr. Robert Parker and declared that hee deteyneth his servant John Casor negro under the pretence that said negro was a free man. The court seriously consideringe and maturely weighing the premisses, doe fynde that the saide Mr. Robert Parker most unjustly keepeth the said Negro from Anthony Johnson his master ... It is therefore the Judgement of the Court and ordered That the said John Casor Negro forthwith returne unto the service of the said master Anthony Johnson, And that Mr. Robert Parker make payment of all charges in the suit.
In sustaining the claim of Johnson to the perpetual service of Casor, the court also gave judicial sanction to the right of free blacks to own slaves of their own race. In a 1916 article, John H. Russell wrote, "Indeed no earlier record, to our knowledge, has been found of judicial support given to slavery in Virginia except as a punishment for a crime." Russell makes that distinction because in 1640, John Punch "was reduced from his former condition of servitude for a limited time to a condition of slavery for life."
