Marital coercion


Marital coercion was a defence to most crimes under English criminal law and under the criminal law of Northern Ireland. It is similar to duress. It was abolished in England and Wales by section 177 of the Anti-social Behaviour, Crime and Policing Act 2014, which came into force on 13 May 2014. The abolition does not apply in relation to offences committed before that date.

Legislation

What had remained of the original common law defence of marital coercion at the date of abolition was contained in of the Criminal Justice Act 1925:
Section 37 of the Criminal Justice Act 1945 is identical to the section cited above and applies to Northern Ireland.

Differences from duress

While the defence of marital coercion has similarities to that of duress, it has significant differences:
In 1977, the Law Commission recommended that the defence of marital coercion should be abolished altogether. They said that they did not consider it to be appropriate to modern conditions. However no action was taken until after Vicky Pryce advanced the defence of marital coercion at her 2013 trial for perverting the course of justice. She argued that she falsely accepted penalty points under the coercion of her former husband and Liberal Democrat Secretary of State for Energy and Climate Change Chris Huhne MP. Her use of the defence was unsuccessful, and she was unanimously convicted on 7 March 2013. In 2014, the government announced the defence would be abolished.

Example from the 18th century

Mary Day was acquitted of theft committed in obedience to her husband at the Old Bailey on 14 January 1732.

Outside the United Kingdom

In the United States, the defense formerly existed in most jurisdictions. It has since been abolished in several states, including those adopting or influenced by the Model Penal Code, section 2.09 of which expressly ends the presumption and abolishes the defense.
In Ireland the case of State v Walsh and Conneely in 1981 found that presumption of marital coercion had not survived the enactment of the 1937 Constitution and so the defence is no longer available there.
By the Crimes Act 1924, paragraph 4 of to the Crimes Act 1900 abolished the defence in New South Wales, Australia.
