The High Court has provisionally fixed 1 March as the hearing date for proceedings brought by a man, allegedly involved with Islamic extremists, aimed at preventing his deportation from Ireland.

The man, who cannot be identified for legal reasons, has brought proceedings arising out of a decision taken by the authorities last March not to renew his residency permit.

The State claims the man has consulted with senior violent extremist leaders outside Ireland, made travel arrangements for and is involved in recruiting members for Islamic extremist group ISIL, also known as the Islamic State.

He denies he has acted on behalf of ISIL or represents a threat to national security.

The man, who has been living here since 2000, secured residency here on the basis that his son, an Irish citizen, was born here.

His residency permit was not renewed because his son has been living overseas.

The Irish authorities then informed the man of their intention to deport him to a Middle East country where he fears he will be tortured because of his political activism.

The man's proceedings were briefly mentioned before the High Court registrar dealing with asylum matters. Lawyers for the State sought an accelerated hearing of the case.

Michael Lynn SC for the man said his client has no difficulty in the matter being given priority.

The matter was provisionally fixed for hearing on 1 March, and the case is expected to take two days to hear.

It was also agreed between the parties that the State's opposition to the man application will be provided to his legal team within three weeks.

The matter was previously before the courts when the man obtained a temporary injunction in December preventing his deportation from Ireland. 

On 28 December the State had that injunction set aside by the High Court after claiming the man represented a risk to national security.

That discharge decision was then appealed to the Court of Appeal.

Plans to deport the man were dramatically put on hold following an intervention by the European Court of Human Rights.

It asked the State not to deport the man from Ireland until his legal proceedings challenging the planned deportation are concluded.

The man's lawyers claim the central issue in those proceedings is whether there is an absolute ban under Article 3 of the European Convention on Human Rights restraining removal from the State of a person who fears being tortured until their legal action has been fully determined.

The State argues exceptions exist which allow it deport the man before his case is heard.

Its assertion that the man is a threat to national security because of his alleged links to ISIL was such an exception, it is argued.

As a result of the European Court's request, it is expected the man will remain in Ireland until his proceedings before the Irish and European courts are dealt with.
