Heath argued for the Crown in Darnel's Case (the Five Knights' Case) of 1627. The judges rejected his argument on absolute prerogative; and a scandal blighted his reputation the following year, when it was revealed, or alleged, by John Selden that he had interfered with the King's Bench records (a felony), in order to promote the decision in the case to a binding precedent (an interpretation that has recently been disputed by Mark Kishlansky). The agitation caused by the business was of major importance for the formulation of the "Petition of Right".
