LAST UPDATE | 19 Nov 2019

GERRY ADAMS’ HISTORIC prison escape convictions should be overturned because his detention without charge was unlawful, the UK’s highest court has heard.

The former Sinn Féin leader claims two 1975 convictions relating to his attempts to escape from the Maze Prison during the early 1970s are unsafe because his detention was not “personally considered” by a senior UK government minister.

Lawyers for Adams (71) argue that because the interim custody order (ICO) used to detain him was not authorised by the then-secretary of state for Northern Ireland, Willie Whitelaw, his detention was unlawful.

Adams attempted to escape from the Maze Prison, also known as Long Kesh internment camp, on Christmas Eve 1973 and again in July 1974. He was later sentenced to a total of four-and-a-half years.

Opening Adams’ case at the Supreme Court in London today, Sean Doran QC said his client’s appeal had been “prompted by the obtaining of materials under the 30-year rule”, under which government papers are made public.

Doran said those documents revealed that there had been “considerable debate within the Northern Ireland Office and the Home Office” about whether Adams had actually been lawfully detained.

He added that a legal opinion requested by Northern Ireland prosecutors prior to Adams’ trial concluded that an ICO had to be personally considered by the secretary of state to be valid.

Doran continued that there was also a note of a meeting in July 1974 held by the then-prime minister Howard Wilson, which he said “confirms that the secretary of state himself did not personally consider the appellant’s case”.

He added that the then-attorney general, Samuel Silkin QC, told the meeting that “there might be as many as 200 persons unlawfully detained in Northern Ireland” as a result of junior ministers authorising ICOs under the previous Conservative government.

In written submissions, Tony McGleenan QC, representing the Director of Public Prosecutions for Northern Ireland, argued that the minister of state who signed the ICO “had the power to do so”.

McGleenan said that the power to make ICOs was designed “to deal with a situation of civil emergency”.

He added: “It would have been impractical or even impossible for the secretary of state to give personal consideration to every request for the making of an ICO.”

McGleenan accepted that Adams’ convictions should be quashed if the Supreme Court ruled in his favour.

The Louth TD was first detained in March 1972, but was released in June that year to take part in secret talks in London before being rearrested in July 1973.

Last year, the Court of Appeal in Belfast heard that, on Christmas Eve 1973, Adams was among four detainees caught attempting to break out of the Maze.

The second escape bid in July 1974 was described as an “elaborate scheme” which involved the kidnap of a man who bore a “striking resemblance” to Adams from a bus stop in west Belfast.

The man was taken to a house where his hair was dyed and he was given a false beard, then taken to the Maze where he was to be substituted for Adams in a visiting hut, the court heard.

However, prison staff were alerted to the plan and Adams was arrested in the car park of the jail, the court was told.

A panel of five Supreme Court justices – led by the former Lord Chief Justice of Northern Ireland, Lord Kerr, and which includes the Lord Chief Justice of England and Wales, Lord Burnett – are expected to reserve their judgment.
