A civil court case brought by three IRA bomb victims against former Sinn Féin leader Gerry Adams opens in London on Monday.
The men are seeking a ruling that he is personally liable for decisions to plant car bombs in London and Manchester in 1973 and 1996.
They are suing him for a nominal £1 in damages for "vindicatory purposes".
Adams has stated he had "no direct or indirect" involvement and has repeatedly denied ever being in the IRA.
The civil case is being heard by Mr Justice Swift at the Royal Courts of Justice.
