The document discusses the canonical impediment of abduction, which refers to the abduction or violent detention of a woman with the intent of marrying her. It outlines the historical background and evolution of the impediment from the 5th century to the Codes of Canon Law of 1917 and 1983. The key elements that constitute the impediment are that the object is a woman, there is abduction or detention, and the intentional element is marriage to the abductor. The impediment ceases if the woman freely consents to marriage after being separated from the abductor and in a safe place.
