The mother and brother of a British army paratrooper shot dead by the IRA in 1991 have launched a legal challenge in the hope of having the new Northern Ireland legacy legislation declared incompatible with human rights law.
Martha and Andy Seaman, from east London, argue the bill enacted last week is a breach of the European convention on human rights because it halted an investigation by the police ombudsman into the notorious murder of Pte Tony Harrison, as well as other unsolved Troubles cases like it.
