After King Charles's death, Henn's Protestantism made him unacceptable to the new Catholic King James II, and he was removed from office in 1687, retiring to his parents house Rooksnest, in Tandridge, Surrey. After the Revolution of 1688, unlike some of Charles II's Irish judges, he showed no interest in returning to the Bench. He lived in retirement at Tandridge till his death in 1708.
